One of ordinary skill will understand that the differing embodiments disclosed in this application can all be used either independently or in combination with each other and there is no limitation implied on such combinations by the order or manner in which embodiments are disclosed.
While the present disclosure will now be described in detail, and it is done so in connection with the illustrative embodiments, it is not limited by the particular embodiments illustrated in the figures and the appended numbered paragraphs.
Panel
One of ordinary skill will understand that the differing embodiments disclosed in this application can all be used either independently or in combination with each other and there is no limitation implied on such combinations by the order or manner in which embodiments are disclosed.
Unless defined otherwise, all technical and scientific terms used herein have the same meanings as commonly understood by one of ordinary skill in the art to which this application belongs. All publications and patents specifically mentioned herein are incorporated by reference in their entirety for all purposes including describing and disclosing the chemicals, instruments, statistical analyses and methodologies which are reported in the publications which might be used in connection with the application. All references cited in this specification are to be taken as indicative of the level of skill in the art. Nothing herein is to be construed as an admission that the application is not entitled to antedate such disclosure by virtue of prior invention.
In the specification and in the claims, the terms “including” and “comprising” are open-ended terms and should be interpreted to mean “including, but not limited to.... “ These terms encompass the more restrictive terms “consisting essentially of” and “consisting of.”
It must be noted that as used herein and in the appended claims, the singular forms “a,” “an,” and “the” include plural reference unless the context clearly dictates otherwise. Further, the terms “a” (or “an”), “one or more” and “at least one” can be used interchangeably herein. It is also to be noted that the terms “comprising,” “including,” “characterized by” and “having” can be used interchangeably. Further, any reactant concentrations described herein should be considered as being described on a weight to weight (w/w) basis, unless otherwise specified to the contrary (e.g., mole to mole, weight to volume (w/v), etc.).
As used herein, the term “glycoside” refers to a molecule in which a sugar (the “glycone” part or “glycone component” of the glycoside) is bonded to a non-sugar (the “aglycone” part or “aglycone component”) via a glycosidic bond.
The terms “steviol glycoside” and “SG” are used interchangeably with reference to a glycoside of steviol, a diterpene compound shown in Formula I, wherein one or more sugar residues are attached to the steviol compound of Formula I.
Steviol glycosides also include glycosides of isomers of steviol (isosteviol) as depicted in Formula II below, and derivatives of steviol, such as 12α-hydroxy-steviol and 15α-hydroxy-steviol.
The terms “glycosidic bond” and “glycosidic linkage” refer to a type of chemical bond or linkage formed between the anomeric hydroxyl group of a saccharide or saccharide derivative (glycone) and the hydroxyl group of another saccharide or a non-saccharide organic compound (aglycone) such as an alcohol. The reducing end of the di- or polysaccharide lies towards the last anomeric carbon of the structure, whereas the terminal end lies in the opposite direction.
By way of example, a glycosidic bond in steviol and isosteviol involves the hydroxyl-group at the sugar carbon atom numbered 1 (so-called anomeric carbon atom) and a hydroxyl-group in the C19 carbonyl group of the steviol or isosteviol molecule building up a so-called O-glycoside or glycosidic ester. Additional glycosidic ester linkages can be formed at the hydroxyl group at C13 of steviol and at the carbonyl oxygen at C16 of isosteviol. Linkages at carbon atoms in the C1, C2, C3, C6, C7, C11, C12 and C15 positions of both steviol and isosteviol yield C-glycosides. In addition, C-glycosides can also be formed at the 2 methyl groups at C18 and C20 in both steviol and isosteviol.
The sugar part can be selected from any sugar with 3-7 carbon atoms, derived from either a dihydroxy-acetone (ketose) or a glycerin-aldehyde (aldose). The sugars can occur in open chain or in cyclic form, as D- or L- enantiomers and in α- or β-conformation.
Representative structures of possible sugar (Sug) conformations exemplified by glucose include D-glucopyranose and L-glucopyranose in which the position 1 is determinative of the α- or β-conformation:

Oligosaccharides comprise disaccharides which include two monosaccharide units, as well as trisaccharides which include three monosaccharide units. A “polysaccharide” consists of long chains of covalently linked monosaccharide units.
The acronym “G-X” or “GX” refers to the glycosylation products of a composition “X”, i.e., product prepared from an enzymatically catalyzed glycosylation process with X and one or more sugar donors as the starting materials. For example, GSG refers to the glycosylation product of a steviol glycoside (SG).
As used herein, the term “Maillard reaction” refers to a non-enzymatic reaction of (1) one or more reducing and/or non-reducing sugars, and (2) one or more amine donors in the presence of heat, wherein the non-enzymatic reaction produces a Maillard reaction product and/or a flavor. Thus, this term is used unconventionally, since it accommodates the use of non-reducing sweetening agents as substrates, which were not heretofore thought to serve as substrates for the Maillard reaction.
The term “reaction mixture” refers to a composition comprising at least one amine donor and one sugar donor, wherein the reaction mixture is to be subjected to a Maillard reaction; a “reaction mixture” is not to be construed as the reaction contents after a Maillard reaction has been conducted, unless otherwise noted.

The term “non-volatile”, as used herein, refers to a compound having a negligible vapor pressure at room temperature, and/or exhibits a vapor pressure of less than about 2 mm of mercury at 20° C.
The term “volatile”, as used herein, refers to a compound having a measurable vapor pressure at room temperature, and/or exhibits a vapor pressure of, or greater than, about 2 mm of mercury at 20° C.
As used herein, the term “sweetener” or “sweetening agent” generally refers to a consumable product, which produces a sweet taste when consumed alone. Examples of sweeteners include, but are not limited to, high-intensity sweeteners (HIS) and derivatives therof, bulk sweeteners, and low sweetness products produced by synthesis, fermentation or enzymatic conversion methods.
As used herein the term “high-intensity sweetener” or “HIS” refers to any synthetic sweetener, semi-synthetic sweetener, sweetener found in nature and derivatives thereof, that is sweeter than sucrose. High-intensity sweeteners are typically many times (e.g., 20 times and more, 30 times and more, 50 times and more or 100 times sweeter than sucrose). For example, sucralose is about 600 times sweeter than sucrose, sodium cyclamate is about 30 times sweeter, Aspartame is about 160-200 times sweeter, and thaumatin is about 2000 times sweeter then sucrose (the sweetness depends on the tested concentration compared with sucrose). High-intensity sweeteners are commonly used as sugar substitutes or sugar alternatives because they are many times sweeter than sugar but contribute only a few to no calories when added to foods. High-intensity sweeteners may also be used to regulate the flavor of foods. High-intensity sweeteners generally will not raise blood sugar levels.
As used herein, the term “natural high-intensity sweetener (NHIS)” refers to HIS found in nature, typically in plants, which may be in raw, extracted, purified, refined, or any other form, singularly or in combination thereof. A NHIS characteristically has higher sweetness potency, but fewer calories than sucrose, fructose, or glucose. Examples of NHIS include, but are not limited to, stevia extracts, sweet tea extracts, swingle extracts, licorice extracts, steviol glycosides, suaviosides, mogrosides, glycyrrhizin and salts thereof.
As used herein, the term “derivatives of NHIS,” includes but is not limited to, (1) glycosylation products of NHIS, (2) Maillard reaction products of NHIS, and (3) Maillard reaction products of the glycosylation products NHIS.
As used herein, the term “synthetic high intensity sweetener (SHIS)” or “artificial high intensity sweetener (AHIS)” refers to high intensity sweeteners that are not found in nature. Examples of SHIS include, but are not limited to, sucralose, aspartame, acesulfame-K (Ace-K), neotame, saccharin and aspartame, glycyrrhizic acid ammonium salt, sodium cyclamate, saccharin, advantame, neohesperidin dihydrochalcone (NHDC), salts and derivatives thereof.
As used herein, the term “bulk sweetener” refers to a sweetener, which typically adds both bulk and sweetness to a confectionery composition and includes, but is not limited to, sugars, sugar alcohols, sucrose, commonly referred to as “table sugar,” fructose, commonly referred to as “fruit sugar,” honey, unrefined sweeteners, syrups, such as agave syrup or agave nectar, maple syrup, corn syrup and high fructose corn syrup (or HFCS).
As used herein, the term “sweetener enhancer” refers to a compound (or composition) capable of enhancing or intensifying sensitivity of the sweet taste. The term “sweetener enhancer” is synonymous with a “sweetness enhancer,” “sweet taste potentiator,” “sweetness potentiator,” and/or “sweetness intensifier.” A sweetener enhancer enhances the sweet taste, flavor, mouth feel and/or the taste profile of a sweetener without giving a detectable sweet taste by the sweetener enhancer itself at an acceptable use concentration. In some embodiments, the sweetener enhancer provided herein may provide a sweet taste at a higher concentration by itself. Certain sweetener enhancers provided herein may also be used as sweetening agents.
Sweetener enhancers can be used as food additives or flavors to reduce the amounts of sweeteners in foods while maintaining the same level of sweetness. Sweetener enhancers work by interacting with sweet receptors on the tongue, helping the receptor to stay switched “on” once activated by the sweetener, so that the receptors respond to a lower concentration of sweetener. These ingredients could be used to reduce the calorie content of foods and beverages, as well as save money by using less sugar and/or less other sweeteners. Examples of sweetener enhancers include, but are not limited to, brazzein, miraculin, curculin, pentadin, mabinlin, thaumatin, and mixtures thereof.
In some cases, sweeteners can be used as sweetener enhancers or flavors when their dosages in food and beverage are low. In some cases, sweetener enhancers can be utilized as sweeteners where their dosages in foods and beverages are higher than dosages regulated by FEMA, EFSA or other related authorities.
As used herein, the phrase “low sweetness products produced by synthesis, fermentation or enzymatic conversion” refers to products that have less sweetness or similar sweetness than sucrose. Examples of low sweetness products produced by extraction, synthesis, fermentation or enzymatic conversion method include, but are not limited to, sorbitol, xylitol, mannitol, erythritol, trehalose, raffinose, cellobiose, tagatose, DOLCIA PRIMA™ allulose, inulin, N--[N-[3-(3-hydroxy-4-methoxyphenyl)propyl]-alpha-aspartyl]-L-phenylalanine 1-methyl ester, glycyrrhizin, and mixtures thereof.
For example, “sugar alcohols” or “polyols” are sweetening and bulking ingredients used in manufacturing of foods and beverages. As sugar substitutes, they supply fewer calories (about a half to one-third fewer calories) than sugar, are converted to glucose slowly, and are not characterized as causing spiked increases in blood glucose levels.
Sorbitol, xylitol, and lactitol are exemplary sugar alcohols (or polyols). These are generally less sweet than sucrose, but have similar bulk properties and can be used in a wide range of food and beverage products. In some case, their sweetness profile can be fine-tuned by being mixed together with high-intensity sweeteners.
The terms “flavor” and “flavor characteristic” are used interchangeably with reference to the combined sensory perception of one or more components of taste, aroma, and/or texture.
The terms “flavoring agent”, “flavoring” and “flavorant” are used interchangeably with reference to a product added to food or beverage products to impart, modify, regulate or enhance the flavor of food. As used herein, these terms do not include substances having an exclusively sweet, sour, or salty taste (e.g., sugar, vinegar, and table salt).
The term “natural flavoring substance” refers to a flavoring substance obtained by physical processes that may result in unavoidable but unintentional changes in the chemical structure of the components of the flavoring (e.g., distillation and solvent extraction), or by enzymatic or microbiological processes, from material of plant or animal origin.
The term “synthetic flavoring substance” refers to a flavoring substance formed by chemical synthesis.
The term “regulate,” as used herein, includes reducing, enhancing or modifying the sensory perception of a flavor characteristic without changing the nature or quality thereof.
The term “enhance,” as used herein, includes augmenting, intensifying, accentuating, magnifying, and potentiating the sensory perception of a flavor characteristics.
Unless otherwise specified, the terms “modify” or “modified” as used herein, includes altering, varying, suppressing, depressing, fortifying and supplementing the sensory perception of a flavor characteristic where the quality or duration of such characteristic was deficient.
The phrase “sensory profile” or “taste profile” is defined as the temporal profile of all basic tastes of a sweetener. The onset and decay of sweetness when a sweetener is consumed, as perceived by trained human tasters and measured in seconds from first contact with a taster’s tongue (“onset”) to a cutoff point (typically 180 seconds after onset), is called the “temporal profile of sweetness.” A plurality of such human tasters is called a “sensory panel”. In addition to sweetness, sensory panels can also judge the temporal profile of the other “basic tastes”: bitterness, saltiness, sourness, piquance (aka spiciness), and umami (aka savoriness or meatiness). The onset and decay of bitterness when a sweetener is consumed, as perceived by trained human tasters and measured in seconds from first perceived taste to the last perceived aftertaste at the cutoff point, is called the “temporal profile of bitterness”.
The phrase “sucrose equivalence” or “SugarE” is the amount of non-sucrose sweetener required to provide the sweetness of a given percentage of sucrose in the same food, beverage, or solution. For instance, a non-diet soft drink typically contains 12 grams of sucrose per 100 ml of water, i.e., 12% sucrose. This means that to be commercially accepted, diet soft drinks must generally have the same sweetness as a 12% sucrose soft drink, i.e., a diet soft drink must have a 12% SugarE. Soft drink dispensing equipment assume an SugarE of 12%, since such equipment is set up for use with sucrose-based syrups.
As used herein, the term “off-taste” refers to an amount or degree of taste that is not characteristically or usually found in a beverage product or a consumable product of the present disclosure. For example, an off-taste is an undesirable taste of a sweetened consumable to consumers, such as, a bitter taste, a licorice-like taste, a metallic taste, an aversive taste, an astringent taste, a delayed sweetness onset, a lingering sweet aftertaste, and the like, etc.
The term “orally consumable product” refers to a composition that can be drunk, eaten, swallowed, inhaled, ingested or otherwise in contact with the mouth or nose of man or animal, including compositions which are taken into and subsequently ejected from the mouth or nose. Orally consumable products are safe for human or animal consumption when used in a generally acceptable range.
As used herein, the term “fruit” refers to firm fruits, soft fruits, sliced pieces with skin remaining, and/or dried/scarified/pricked/scraped fruit, which are well-known in the art, and described herein. Examples of fruit include, but are not limited to, apple, pear, orange, tangerine, lemon, lime, apricot, plum, prune, kiwi, guava, pineapple, coconut, papaya, mango, grape, cherry, pomegranate, grape fruit passion fruit, dragon fruit, melons and berries. Example of berries include, but are not limited to, cranberry, blueberry, boysenberry, elderberry, chokeberry, lingonberry, raspberry, mulberry, gooseberry, huckleberry, strawberry, blackberry, cloudberry, blackcurrant, redcurrant and white currant.

As used herein, the term “salt” refers to a chemical compound consisting of an ionic assembly of positively charged cations and negatively charged anions, which results in a compound with no net electric charge. A common example is table salt, with positively charged sodium ions and negatively charged chloride ions. The salt in this specification means all edible salts, including but not limited to NaCl based salts such as table salt, kosher salt, Himalayan salt, sea salt, Hawaiian salt, flake salt, pickling salt and iodionized salt, MgCh, CaCl2, KCl, and trisodium citrate.
Unless otherwise noted, the term “ppm” (parts per million) means parts per million on a v/v or wt/wt basis.
Traditionally, chemical compounds such as menthol, menthone, methyl acetate and essential oils such as peppermint oil have been used to provide a cooling effect both orally and topically. These products are used in applications such as body wash, shampoo, mouthwash, toothpaste, chewing gum, mint confection, cooling ointment, medicated oils, insect repellent etc. However, these products have certain drawbacks. When conventional cooling agents, such as menthol, are present in compositions in excess, a bitter or burn feeling may be produced, making the final products undesirable. There is need to develop natural cooling agents or regulators to meet market taste requirements. The inventor has surprisingly found that combining composition in this invention could regulate the intensity and longevity of coolingness and provide a palatable taste.
Transient receptor potential melastatin 8 (TRPM8) is a polymodal, Ca2+permeant, and non-selective cation channel, identified as the physiological sensor of environmental cold. TRPM8 channels are mainly expressed in a subpopulation of sensitive primary afferent neurons, which innervate highly cold-sensitive tissues, including skin, the oral cavity, epithelium, teeth, nasal mucosa, tongue, and cornea. The oral cavity includes oral cavity includes the lips, hard palate (the bony front portion of the roof of the mouth), soft palate (the muscular back portion of the roof of the mouth), retromolar trigone (the area behind the wisdom teeth), front two-thirds of the tongue, gingiva (gums), buccal mucosa (the inner lining of the lips and cheeks), and floor of the mouth under the tongue. TRPM8 channels are also expressed in the visceral tissues innervated by pelvic or vagal nerves in e.g., the bladder, male urinary, genital tract, spermatic chord, colon, and pulmonary tissues.
TRPM8 channels can be regulated by natural and synthetic cooling mimetic agents, such as icilin, eucalyptol, menthol and its derivatives, camphor, eucalyptol, linalool, geraniol, hydroxycitronellal, cooling agent 10, CPS-113, CPS-369, Frescolat ML, Frescolat MGA, and an abundance of agonists, such as WS-12. The inventor has surprisingly found that compositions of the present application regulate a cooling effect or taste. While not wishing to be bound by theory, it is believed that the components in the compositions of the present application, including both the one or more NHIS and/or derivatives thereof, and conventional cooling agents could regulate the TRPM8 channel.
In one aspect, the present application provides a composition comprising one or more NHIS and/or derivatives thereof that regulate a coolness taste, feeling or flavor of the composition, wherein the one or more high intensity natural sweetener and/or derivative thereof are present in the composition in a total amount sufficient for regulating a cooling effect or taste. In some embodiments, the composition of the present application provides or enhances a cooling effect or taste.
In some embodiments, the composition of the present application comprises one or more NHIS and/or derivatives thereof selected from the group consisting of stevia extracts (SEs), glycosylated stevia extracts (G-SEs), stevia extract-MRPs (SE-MRPs), glycosylated stevia extract-MRPs (G-SE-MRPs), stevia glycosides (SGs), glycosylated stevia glycosides (GSGs), stevia glycoside-MRPs (SG-MRPs), glycosylated stevia glycoside-MRPs (GSG-MRPs), sweet tea extracts (STEs), glycosylated sweet tea extracts (G-STEs), sweet tea extract-MRPs (STE-MRPs), glycosylated sweet tea extract-MRPs (G-STE-MRPs), sweet tea glycosides (STGs), glycosylated sweet tea glycosides (G-STGs), sweet tea glycoside-MRPs (STG-MRPs), glycosylated sweet tea glycoside-MRPs (G-STG-MRPs), monk fruit extracts (MFEs), glycosylated monk fruit extracts (G-MFEs), monk fruit glycosides (MFGs), glycosylated monk fruit glycosides (G-MFGs), monk fruit glycoside-MRPs (MFG-MRPs), and glycosylated monk fruit glycoside-MRPs (G-MFG-MRPs).
In certain preferred embodiments, the one or more NHIS and/or derivatives thereof is further combined with one or more cooling agent(s).
Without wishing to be bound by theory, it is believed that the one or more NHIS and/or derivatives thereof of the present application can increase the solubility of cooling agents, improve their penetrating capability and prolong their retention time in the mucous membranes present in the oral cavities, including e.g., mouth, nose, breathing tube, lung, and skin, thereby lowering their threshold for achieving a cool feeling.
Taste receptors are normally regarded by location on the tongue, where they are expressed in taste cells of taste buds. However, taste receptors have been identified in other tissues ranging from the lungs and guts to the brain. These so called “extra-oral” taste receptors play hidden roles such as local chemoreceptors in the body and local effects on innate immunity. For instance, bitter taste receptors TAS2Rs are expressed not only in the oral cavity but also in many extraoral tissues including gastrointestine, nasal epithelium, airway, skin, heart and brain.
The compositions of the present application can regulate both taste and flavor sensory receptors located in mouth cavity, nose cavity, breathing airway and food tubes. On the tongue, bitter (T2R), sweet (T1R2/T1R3), and Umami (T1R1/T1R3) receptors are expressed in distinct cells of the taste bud called type II cells. Each taste cell can detect one type of taste (unisensory), and coupling of that cell to different afferent gustatory neurons dictates how the response is perceived by the brain. There are also multi-taste sensory receptors in a single cell such as bitter and sweet taste receptors co-expressed together in many extraoral chemosensory cell types, such as intestinal tuft cells and solitary chemosensory cells.
In certain embodiments, glycoside components of the present application may regulate one or more multi-taste sensory receptors, such as TRPM5, TRPM8, T1R2, T1R3, T1R1/T1R3, TAS2R4 etc. This can potentiate the activities of sweet, umami, bitter, salt, cooling channel simultaneously. Contrary to current prevailing knowledge that single stimuli regulates single taste sensation and transfers the resulting signals parallel with other taste sensation to brain for final integration of overall flavor and taste via neuronal perceptive pathways, it is believed that stimuli resulting from the glycoside components of the present application can regulate multi-taste sensations and transfer multi-signals therefrom parallel to brain, and can further regulate di, tri, tetra etc. multi-functional taste receptors, such as e.g., T1R1/TIR3 receptors responsible for sweet and umami, and sweet/bitter taste receptors in solitary chemosensory cells and transfer the signals therefrom via local congruent neurons. For instance, SG-MRPs can regulate sweet, bitter, umami, kokumi taste receptors and also the di, tri, tetra receptors, as well as flavor receptors in the olfactory bulb. It is essential to have products that can regulate at least two distinct taste receptors and their co-taste receptors (such as T1R1/T1R3) in formulation to make food and beverages more palatable. Compositions of the present application can produce different distinct stimuli and harmonize the overall flavor and taste of foods and beverages.

In summary, there are at least other two types of neuronal perceptive pathways: groups of substances, including those described in the compositions of the present application, a single stimuli could regulate multi-independent single-taste receptors (sensing one taste only such as sweet or bitter, or umami or cooling) simultaneously, it could regulate the signals of cell to cell communication, attenuates signals by inputting different concentration of stimuli. There are groups of substances, a single stimuli could mainly regulate the multi-taste receptors (both sweet and bitter, both sweet and umami, combination of sweet/bitter/umami etc.) and transfer the signals via congruent neurons to the brain. Like multi-sensory interactions in connection with the ventriloquism effect, in which the spatial properties of stimuli presented in one modality can influence the spatial content of perception in another modality simultaneously, the inventor believes that different basic tastes, including sweet, bitter and umami also interact with each other in the course of neuronal perceptive pathways through congruent neurons before final integration of overall taste and flavor is achieved. There are spatially distributed neurons in the neuronal perceptive pathways, where both neurons respond to single-taste signals or neurons response to multi-taste signals present.
In some embodiments, the composition of the present application comprises one or more NHIS and/or glycosylated NHIS.
NHISs of the present application include, but are not limited to, Stevia extracts (SEs), steviol glycosides (SGs), sweet tea extracts (STE), sweet tea glycosides (STGs) such as sauviosides, monk fruit extracts (MFEs) and morgrosides.
Some of the SGs for use in the compositions and consumable products described herein include those described in Table B-2. In Table B-2, the phrase “# Added sugar moieties” means sugar moieties added to the steviol or isosteviol backbone. The “added sugar moieties” are native to the respective steviol glycoside and are NOT sugar groups added in an exogenous glycosylation reaction.
As described above, the present application provides compositions that may include one or more glycosylated NHIS formed from a reaction mixture containing a NHIS. As used herein, a glycosylated NHIS may also be referred to as a derivative of NHIS.
Generally, the glycosylated NHIS of the present application is prepared as follows: (i) dissolving a sugar-donor material in water to form a liquefied sugar-donor material; (ii) adding a starting NHIS composition to liquefied sugar-donor material to obtain a mixture; and (iii) adding an effective amount of an enzyme to the mixture to form a reaction mixture, wherein the enzyme catalyzes the transfer of sugar moieties from the sugar-donor material to the SG in the starting NHIS composition; and (iv) incubating the reaction mixture at a desired temperature for a desired length of reaction time to glycosylate the NHIS in the starting NHIS composition with sugar moieties present in the sugar-donor molecule.
After achieving a desired ratio of glycosylated NHIS and residual NHIS (i.e., unreacted NHIS) contents, the reaction mixture can be heated to a sufficient temperature for a sufficient amount of time to inactivate the enzyme. In some embodiments, the enzyme is removed by filtration in lieu of inactivation. In other embodiments, the enzyme is removed by filtration following inactivation. In some embodiments the sugar is glucose and the sugar donor is a glucose donor. In some embodiments, the glucose donor is starch. In some embodiments the resulting solution comprising glycosylated NHIS, residual NHIS and dextrin is decolorized.
In some embodiments the resulting solution of glycosylated NHIS, including residual NHIS and dextrin is dried. In some embodiments, the drying is by spray drying. In some embodiments, step (i) comprises the substeps of (a) mixing a glucose-donor material with a desired amount of water to form a suspension, (b) adding a desired amount of enzyme to the suspension and (c) incubate the suspension at a desired temperature for a desired time to form liquefied glucose-donor material.

In some embodiments, the glycosylated NHIS is a mono-glycosylated, di-glycosylated, tri-glycosylated, tetra-glycosylated, or penta-glycosylated glycosylation product of a NHIS.
The glycosylated NHIS of the present application can be prepared by an enzyme-mediated or non-enzyme-mediated process in which one or more sugar residues are transferred from one or more sugar donors to a substrate to produce a glycosylated NHIS product, such as a GSG product. This process is referred to hereinafter as a glycosylation reaction.
In some embodiments, the glycosylated NHIS product is a GSG product. The GSGs of the present application can also be prepared by a enzyme-mediated or nonenzyme-mediated process in which one or more sugar residues are removed from a GSG substrate to produce a new GSG product. This process is referred to hereinafter as a conversion reaction. The substrate of a conversion reaction can be, for example, a GRA, GRB, GRC, GRD, GRE, GRF, GRI, GRM, GRN, GRO, glycosylated steviolmonoside, glycosylated steviolbioside, glycosylated dulcoside, glycosylated rubusoside or glycosylated stevioside.
In some embodiments, the glycosylated NHIS products described in the present application, such as the GSG products, are formed by an exogenous glycosylation reaction in the present of a glycosyltransferase.
As used herein, a “glycosyltransferase” refers to an enzyme that catalyzes the formation of a glycosidic linkage to form a glycoside. A glycoside is any molecule in which a sugar group is bonded through its anomeric carbon to another group via a glycosidic bond. Glycosides can be linked by an O- (an O-glycoside), N- (a glycosylamine), S- (a thioglycoside), or C- (a C-glycoside) glycosidic bond. The sugar group is known as the glycone and the non-sugar group is known as the aglycone. The glycone can be part of a single sugar group (monosaccharide) or several sugar groups (oligosaccharide). A glycosyltransferase according to the present application further embraces “glycosyltransferase variants” engineered for enhanced activities.
Glycosyltransferases utilize “activated” sugar phosphates as glycosyl donors, and catalyze glycosyl group transfer to an acceptor molecule comprising a nucleophilic group, usually an alcohol. A retaining glycosyltransferases is one which transfers a sugar residue with the retention of anomeric configuration. Retaining glycosyltransferase enzymes retain the stereochemistry of the donor glycosidic linkage after transfer to an acceptor molecule. An inverting glycosyltransferase, on the other hand, is one which transfers a sugar residue with the inversion of anomeric configuration. Glycosyltransferases are classified based on amino acid sequence similarities. Glycosyltransferases are classified by the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology (NC-IUBMB) in the enzyme class of EC 2.4.1 on the basis of the reaction catalyzed and the specificity.
Glycosyltransferases can utilize a range of donor substrates. Based on the type of donor sugar transferred, these enzymes are grouped into families based on sequence similarities. Exemplary glycosyltransferases include glucanotransferases, N-acetylglucosaminyltransferases, N-acetylgalactosaminyltransferases, fucosyltransferases, mannosyltransferases, galactosyltransferases, sialyltransferases, galactosyltransferases, fucosyltransferase, Leloir glycosyltransferases, non-Leloir glycosyltransferases, and other glycosyltransferases in the enzyme class of EC 2.4.1. The Carbohydrate-Active Enzymes database (CAZy) provides a continuously updated list of the glycosyltransferase families.
In some embodiments, the glycosylated NHIS products are formed from a reaction mixture comprising an exogenous glycosyltransferase classified as an EC 2.4.1 enzyme, including but not limited to members selected from the group consisting of cyclomaltodextrin glucanotransferase (CGTase; EC 2.4.1.19), amylosucrase (EC 2.4.1.4), dextransucrase (EC 2.4.1.5), amylomaltase, sucrose:sucrose fructosyltransferase (EC 2.4.1.99), 4-α-glucanotransferase (EC 2.4.1.25), lactose synthase (EC 2.4.1.22), sucrose-1,6-α-glucan 3(6)-α-glucosyltransferase, maltose synthase (EC 2.4.1.139), alternasucrase (EC 2.4.1.140), including variants thereof.
Cyclomaltodextrin glucanotransferase, also known as CGTase, is an enzyme assigned with enzyme classification number EC 2.4.1.19, which is capable of catalyzing the hydrolysis and formation of (1→4)-α-D-lucosidic bonds, and in particular the formation of cyclic maltodextrins from polysaccharides as well as the disproportionation of linear oligosaccharides.
Dextransucrase is an enzyme assigned with enzyme classification number EC 2.4.1.5, and is also known as sucrose 6-glucosyltransferase, SGE, CEP, sucrose-1,6-α-glucan glucosyltransferase or sucrose: 1,6-α-D-glucan 6-α-D-glucosyltransferase. Dextransucrases are capable of catalyzing the reaction: sucrose + [(1→6)-α-D-glucosyl]n = D-fructose + [(1→6)-α-D-glucosyl]n+1. In addition, a glucosyltransferase (DsrE) from Leuconostoc mesenteroides, NRRL B-1299 has a second catalytic domain (“CD2”) capable of adding alpha-1,2 branching to dextrans (U.S. Pat. Nos. 7,439,049 and 5,141,858; U.S. Pat. Appl. Publ. No. 2009-0123448; Bozonnet et al., J. Bacteria 184:5753-5761, 2002).
Glycosyltransferases and other glycosylating enzymes for use in the present application may be derived from any source and may be used in a purified form, in an enriched concentrate or as a crude enzyme preparation.
In some embodiments, the glycosylation reaction is carried out by glycosylating an aglycone or glycoside substrate using e.g., a nucleotide sugar donor (e.g., sugar mono- or diphosphonucleotide) or “Leloir donor” in conjunction with a “Leloir glycosyltransferase” (after Nobel prize winner, Luis Leloir) that catalyzes the transfer of a monosaccharide unit from the nucleotide-sugar (“glycosyl donor’) to a “glycosyl acceptor”, typically a hydroxyl group in an aglycone or glycoside substrate.
Accordingly, in some embodiments the glycosylated NHIS products of the present application are formed from a reaction mixture comprising a nucleotide sugar.
In certain embodiments, the glycosylation reactions may involve the use of a specific Leloir glycosyltransferase in conjunction with a wide range of sugar nucleotides donors, including e.g., UDP-glucose, GDP-glucose, ADP-glucose, CDP-glucose, TDP-glucose or IDT-glucose in combination with a glucose-dependent glycosyltransferase (GDP-glycosyltransferases; GGTs), ADP-glucose-dependent glycosyltransferase (ADP-glycosyltransferases; AGTs), CDP-glucose-dependent glycosyltransferase (CDP-glycosyltransferases; CGTs), TDP-glucose-dependent glycosyltransferase (TDP-glycosyltransferases;TGTs) or IDP-glucose-dependent glycosyltransferase (IDP-glycosyltransferases; IGTs), respectively.
In particular embodiments, the exogenous glycosylation reaction is carried out using an exogenous Leloir-type UDP-glycosyltransferase enzyme of the classification EC 2.4.1.17, which catalyzes the transfer of glucose from UDP-α-D-glucuronate (also known as UDP-glucose) to an acceptor, releasing UDP and forming acceptor β-D-glucuronoside. In some embodiments, the glycosyltransferases include, but are not limited to, enzymes classified in the GT1 family. In certain preferred embodiment, the glycosylation reaction is catalyzed by an exogenous UDP-glucose-dependent glycosyltransferase. In some embodiments, the glycosylation reaction is catalyzed by a glycosyltransferase capable of transferring a non-glucose monosaccharide, such as fructose, galactose, ribose, arabinose, xylose, mannose, psicose, fucose and rhamnose, and derivative thereof, to the recipient.
U.S. Pat. No. 9,567,619 describes several UDP-dependent glycosyltransferases that can be used to transfer monosaccharides to rubusoside, including UGT76G1 UDP glycosyltransferase, HV1 UDP-glycosyltransferase, and EUGT11, a UDP glycosyltransferase-sucrose synthase fusion enzyme. The EUGT11 fusion enzyme contains a uridine diphospho glycosyltransferase domain coupled to a sucrose synthase domain and can exhibit 1,2-β glycosidic linkage and 1,6-β glycosidic linkage enzymatic activities, as well as sucrose synthase activity. Of the foregoing enzymes, UGT76G1 UDP glycosyltransferase contains a 1,3-O-glucose glycosylation activity which can transfer a second glucose moiety to the C-3′ of 13-O-glucose of rubusoside to produce rebaudioside G (“Reb G”); HV1 UDP-glycosyltransferase contains a 1,2-O-glucose glycosylation activity which can transfer a second glucoside moiety to the C-2′ of 19-O-glucose of rubusoside to produce rebaudioside KA (“Reb KA”); and the EUGT11 fusion enzyme contains a 1,2-O-glucose glycosylation activity which transfers a second glucose moiety to the C-2′ of 19-O-glucose of rubusoside to produce rebaudioside KA or transfer a second glucose moiety to the C-2′ of 13-O-glucose of rubusoside to produce stevioside. In addition, HV1 and EUGT11 can transfer a second sugar moiety to the C-2′ of 19-O-glucose of rebaudioside G to produce rebaudioside V (“Reb V”) and can additionally transfer a second glucose moiety to the C-2′ of 13-O-glucose of rebaudioside KA to produce rebaudioside E (“Reb E”). Furthermore, when used singly or in combination, these enzymes can be used to generate a variety of steviol glycosides known to be present in Stevia rebaudiana, including rebaudioside D (“Reb D”) and rebaudioside M (“Reb M”).
In some embodiments, monosaccharides that can be transferred to a saccharide or monosaccharide acceptor include, but are not limited to glucose, fructose, galactose, ribose, arabinose, xylose, mannose, psicose, fucose and rhamnose, and derivative thereof, as well as acidic sugars, such as sialic acid, glucuronic acid and galacturonic acid.
In some embodiments, glycosylation of SGs is driven by an exogenous glycosyl hydrolase (GH). GHs normally cleave a glycosidic bond. However, they can be used to form glycosides by selecting conditions that favor synthesis via reverse hydrolysis. Reverse hydrolysis is frequently applied e.g., in the synthesis of aliphatic alkylmonoglucosides.
Glycosyl hydrolases have a wide range of donor substrates employing usually monosaccharides, oligosaccharides or/and engineered substrates (i.e., substrates carrying various functional groups). They often display activity towards a large variety of carbohydrate and non-carbohydrate acceptors. Glycosidases usually catalyze the hydrolysis of glycosidic linkages with either retention or inversion of stereochemical configuration in the product.
In some embodiments, the GRGs of the present application are formed from a reaction mixture comprising an exogenous glycosyl hydrolase, classified as an EC 3.2.1 enzyme, including but not limited to alpha-glucosidase, beta-glucosidase and beta-fructofuranosidase.
Exemplary glycosyl hydrolases for use in the present application include, but are not limited to α-amylases (EC 3.2.1.1), α-glucosidases (EC 3.2.1.20), β-glucosidases (EC 3.2.1.21), α-galactosidases (EC 3.2.1.22), β-galactosidases (EC 3.2.1.23), α-mannosidase (EC 3.2.1.24), β-mannosidase (EC 3.2.1.25), β-fructofuranosidase (EC 3.2.1.26), amylo-1,6-glucosidases (EC 3.2.1.33), β-D-fucosidases (EC 3.2.1.38), α-L-rhamnosidases (EC 3.21.40), glucan 1,6-α-glucosidases (EC 3.2.70), and variants thereof.
In some embodiments, the GRGs of the present application are formed using a class of glycoside hydrolases or glycosyltransferases known as “transglycosylases.” As used herein, the term “transglycosylase” and “transglycosidase” (TG) are used interchangeably with reference to a glycoside hydrolase (GH) or glycosyltransferase (GT) enzyme capable of transferring a monosaccharide moiety from one molecule to another. Thus, a GH can catalyze the formation of a new glycosidic bond either by transglycosylation or by reverse hydrolysis (i.e., condensation).
The acceptor for transglycosylase reaction acceptor can be saccharide acceptor or a monosaccharide acceptor. Thus, a transglycosidase can transfer a monosaccharide moiety to a diverse set of aglycones, including e.g., monosaccharide acceptors, such as aromatic and aliphatic alcohols. Transglycosidases can transfer a wide variety of monosaccharides (D- or L-configurations) to saccharide acceptors, including glycosides, as well as monosaccharide acceptors, including a wide variety of flavonoid aglycones, such as naringenin, quercetin, hesperetin.
Monosaccharides that can be transferred to a saccharide or monosaccharide acceptor include, but are not limited to glucose, fructose, galactose, ribose, arabinose, xylose, mannose, psicose, fucose and rhamnose, and derivative thereof, as well as acidic sugars, such as sialic acid, glucuronic acid and galacturonic acid. The term “transglucosidase” is used when the monosaccharide moiety is a glucose moiety.
Transglycosidases include GHs or GTs from the enzyme classes of EC 3.2.1 or 2.4.1, respectively. In spite of the inclusion of certain glycosyltransferases as transglycosidases, TGs are classified into various GH families on the basis of sequence similarity. A large number of retaining glycosidases catalyze both hydrolysis and transglycosylation reactions. In particular, these enzymes catalyze the intra- or intermolecular substitution of the anomeric position of a glycoside. Under kinetically controlled reactions, retaining glycosidases can be used to form glycosidic linkages using a glycosyl donor activated by a good anomeric leaving group (e.g., nitrophenyl glycoside). In contrast, thermodynamically controlled reverse hydrolysis uses high concentrations of free sugars.
Transglycosidases corresponding to any of the GH families with notable transglycosylase activity may be used in the present application, and may include the use of e.g., members of the GH2 family, including LacZ β-galactosidase, which converts lactose to allolactose; GH13 family, which includes cyclodextran glucanotransferases that convert linear amylose to cyclodextrins, glycogen debranching enzyme, which transfers three glucose residues from the four-residue glycogen branch to a nearby branch, and trehalose synthase, which catalyzes the interconversion of maltose and trehalose; GH16 family, including xyloglucan endotransglycosylases, which cuts and rejoins xyloglucan chains in the plant cell wall; GH31, for example, α-transglucosidases, which catalyze the transfer of individual glucosyl residues between α-(1→4)-glucans; GH70 family, for example, glucansucrases, which catalyze the synthesis of high molecular weight glucans, from sucrose; GH77 family, for examples amylomaltase, which catalyzes the synthesis of maltodextrins from maltose; and the GH23, GH102, GH103, and GH104 families, which include lytic transglycosylases that convert peptidoglycan to 1,6-anhydrosugars.
In one embodiment, the glycosyltransferase is a transglucosylase from the glycoside hydrolase 70 (GH70) family. GH70 enzymes are transglucosylases produced by lactic acid bacteria from, e.g., Streptococcus, Leuconostoc, Weisella or Lactobacillus genera. Together with the families GH13 and GH77 enzymes, they form the clan GH-H. Most of the enzymes classified in this family use sucrose as the D-glucopyranosyl donor to synthesize α-D-glucans of high molecular mass (>106 Da) with the concomitant release of D-fructose. They are also referred to as glucosyltransferases or glucansucrases.
A wide range of α-D-glucans, varying in size, structure, degree of branching and spatial arrangements can thus be produced by GH70 family members. For example, GH70 glucansucrases can transfer D-glucosyl units from sucrose onto hydroxyl acceptor groups. Glucansucrases catalyze the formation of linear as well as branched α-D-glucan chains with various types of glycosidic linkages, namely α-1,2; α-1,3; α-1,4; and/or α-1,6.
In addition, sucrose analogues such as α-D-glucopyranosyl fluoride, p-nitrophenyl α-D-glucopyranoside, α-D-glucopyranosyl α-L-sorofuranoside and lactulosucrose can be utilized as D-glucopyranosyl donors. A large variety of acceptors may be recognized by glucansucrases, including carbohydrates, alcohols, polyols or flavonoids to yield oligosaccharides or gluco-conjugates.
Exemplary glucansucrases for use in the present application include e.g., dextransucrase (sucrose:1,6-α-D-glucosyltransferase; EC 2.4.1.5), alternansucrase (sucrose:1,6(1,3)-α-D-glucan-6(3)-α-D-glucosyltransferase, EC 2.4.1.140), mutansucrase (sucrose:1,3-αD-glucan-3-α-D-glucosyltransferase; EC 2.4.1.125), and reuteransucrase (sucrose:1,4(6-α-D-glucan-4(6)-αD-glucosyltransferase; EC 2.4.1.-). The structure of the resultant glucosylated product is dependent upon the enzyme specificity.
In some embodiments, a fructosyltransferase may be used to catalyze the transfer of one or more fructose units, optionally comprising terminal glucose, of the following sequence: (Fru)n-Glc consisting of one or more of: β 2,1, β 2,6, α 1,2 and β-1,2 glycosidic bonds, wherein n typically is 3-10. Variants include Inulin type β-1,2 and Levan type β-2,6 linkages between fructosyl units in the main chain. Exemplary fructosytransferase for use in the present application include e.g., β-fructofuranosidase (EC 3.2.1.26), inulosucrase (EC 2.4.1.9) levansucrase (EC 2.4.1.10), or endoinulinase.
In some embodiments, a galactosyltransferase or β-galactosidase may be used to catalyze the transfer of multiple saccharide units, in which one of the units is a terminal glucose and the remaining units are galactose and disaccharides comprising two units of galactose. In certain embodiments, the resulting structure includes a mixture of galactopyranosyl oligomers (DP=3-8) linked mostly by β-(1,4) or β-(1,6) bonds, although low proportions of β-(1,2) or β-(1,3) linkages may also be present. Terminal glucosyl residues are linked by β-(1,4) bonds to galactosyl units. These structures may be synthesized by the reverse action of β-galactosidases (EC 3.2.1.23) on lactose at relatively high concentrations of lactose.
In some embodiments, the transglycosidase is an enzyme having trans-fucosidase, trans-sialidase, trans-lacto-N-biosidase and/or trans-N-acetyllactosaminidase activity.

In these reactions, the transglycosylase and the glycosyl hydrolase or transglycosidase may be present in a range of ratios (w/w), wherein the transglycosylase/glycosyl hydrolase ratio (w/w) ranges from 100:1, 80:1, 60:1, 40:1, 30:1, 25:1, 20:1, 15:1, 10:1, 9:1, 8:1, 7:1, 6:1, 5:1, 4:1, 3:1, 2:1, 1:1, 1:2, 1:3, 1:4, 1:5, 1:6, 1:7, 1:8, 1:9, 1:10, 1:15, 1:20, 1:25, 1:30, 1:40, 1:50, 1:60, 1:80, 1:100, or any ratio derived from any two of the aforementioned integers.

The enzymatically catalyzed reaction can be carried out batch wise, semi-batch wise or continuously. Reactants can be supplied at the start of reaction or can be supplied subsequently, either semi-continuously or continuously. The catalytic amount of glycosidase or glycosyltransferase required for the method of the invention depends on the reaction conditions, such as temperature, solvents and amount of substrate.
The reaction can be performed in aqueous media such as buffer. A buffer adjusts the pH of the reaction mixture to a value suitable for effective enzymatic catalysis.

Suitable organic solvents comprise alkanones, alkylnitriles, tertiary alcohols and cyclic ethers, and mixtures thereof, for example, acetone, acetonitrile, t-pentanol, t-butanol, 1,4-dioxane and tetrahydrofuran, and mixtures thereof. Generally, the use of organic solvents is not preferred.
The final product of the glycosylation reaction, such as glycosylated rubusoside and glycosylated stevioside, may be further purified to remove residual sugar donor, such as maltodextrin.
In some embodiments, a GSG, such as glycosylated rubusoside is subjected to enzyme treatment (e.g., α-amylase treatment) to produce a GSG with reduced level of glycosylation (e.g., GSG with shortened side chains at the glycosylation sites) compared to the pre-treatment GSG.
In some embodiments, a GSG, such as glycosylated rubusoside, is subjected to another glycosylation reaction to produce GSGs with increased level of glycosylation (e.g., elongated side chains at the glycosylation sites) compared to the pre-treatment GSG.
In some embodiments, the glycosylated NHIS, such as GSGs, of the present application are formed by an exogenous conversion reaction in the present of a glycosyl hydrolase (GH), which cleaves a glycosidic bond and is thus capable of converting a GSG, such as glycosylated stevioside to another GSG, such as glycosylated rubusoside, by removing a glucose at the C-13 position of the stevioside.
In some embodiments, the glycosylated NHIS, such as GSGs, of the present application are formed by non-enzymatic hydrolysis. The non-enzymatic hydrolysis can be carried out under alkaline or acid conditions. Table C shows an exemplary list of hydrolysis products from natural diterpene glycoside.
In some embodiments, a GSG of the present application are produced by converting an original GSG into another GSG or GSGs by alkaline or acid hydrolysis.
In some embodiments, glycosylated steviolbioside of the present application is produced from glycosylated stevioside. For examples, glycosylated stevioside can be hydrolyzed to remove a glucose unit from the glycoside chain on the C19 carbon of glycosylated stevioside, which converts glycosylated steviolside to glycosylated steviolbioside.
In some embodiments, glycosylated steviolmonoside of the present application is produced from glycosylated rubusoside. For example, glycosylated rubusoside, can be hydrolyzed to remove a glucose unit from the glycoside chain on the C19 carbon of glycosylated rubusoside, which converts glycosylated rubusoside to glycosylated steviolmonoside.
In some embodiments, glycosylated dulcoside B of the present application is produced from GRC. For example, GRC can be hydrolyzed to remove a glucose unit from the glycoside chain on the C19 carbon of GRC, which converts GRC to glycosylated dulcoside B.

In some embodiments, alkaline hydrolysis of the starting or raw material is preferred for simplicity and economics. Sodium hydroxide is the preferred alkali to use for hydrolysis of GRA, GRC, glycosylated stevioside or glycosylated rubusoside, but potassium hydroxide and other well-known alkali used in food processing can also be used.
In some embodiments, the starting or raw materials can include 50 wt % or greater, 55 wt % or greater, 60 wt % or greater, 65 wt % or greater, 70 wt % or greater, 75 wt % or greater, 80 wt % or greater, 85 wt % or greater, 90 wt % or greater, 95 wt % or greater, or 99 wt % or greater of GRA, GRC, glycosylated stevioside or glycosylated rubusoside.
In some embodiments, a GSG starting material is dissolved in water (preferably potable water) to form a solution, alkali is then added to the solution , and the solution temperature is raised preferably to 85° C. to 95° C., and more preferably to 90° C. to start alkaline hydrolysis. If the alkaline hydrolysis is conducted at temperatures lower than 85° C., the reaction proceeds slowly until the alkali is exhausted. The solution is stirred and is maintained at the selected temperature for a duration that provides the desired concentrations of the hydrolysis products in the solution or until the alkali is exhausted. The preferred duration of alkaline hydrolysis at commercial scale is a minimum 30 minutes; shorter durations typically do not exhaust the amounts of alkali used in commercial production. The final product solution (containing both the unhydrolyzed GSG starting material such as GRA, also referred to as “residual GSG”, and the hydrolysis product such as GRB) is typically very close to pH 7.0, but pH can be adjusted (typically by adding HCl or NaOH).
The product solution produced as described above may be brown in color, has a faint “burnt sugar” smell, and has a weak “caramel” taste. Brown color, burnt sugar smell, and caramel taste can be removed by column chromatography such as an activated charcoal column, a polymer resin adsorption column or with an ion exchange column as the chromatography matrix, binding the caramel components to the be column while letting the steviol glycosides pass through. Depending upon the use of the sweetener or flavoring agent of the present application, the brown color, burnt sugar smell, and caramel taste may be desirable, or unnoticeable, in either case avoiding the need to remove the brown color, burnt sugar smell, and caramel taste.
The alkaline hydrolysis products can be kept in solution as a syrup ready for distribution as a liquid sweetener, or dried for distribution as a dry sweetener. Drying is by spray-drying, lyophilization, oven drying, and other drying processes well-known in the art of sweeteners.

The Maillard reaction generally refers to a non-enzymatic browning reaction of a sugar donor with an amine donor in the presence of heat which produces flavor. Common flavors produced as a result of the Maillard reaction include, for example, those associated with red meat, poultry, coffee, vegetables, bread crust etc. subjected to heat. A Maillard reaction relies mainly on sugars and amino acids but it can also contain other ingredients including: autolyzed yeast extracts, hydrolyzed vegetable proteins, gelatin (protein source), vegetable extracts (i.e., onion powder), enzyme treated proteins, meat fats or extracts and acids or bases to adjust the pH of the reaction. The reaction can be in an aqueous environment with an adjusted pH at specific temperatures for a specified amount of time to produce a variety of flavors. Typical flavors include those associated with chicken, pork, beef, caramel, chocolate etc. However, a wide variety of different taste and aroma profiles can be achieved by adjusting the ingredients, the temperature and/or the pH of the reaction. The main advantage of the reaction flavors is that they can produce characteristic meat, burnt, roasted, caramellic, or chocolate profiles desired by the food industry, which are not typically achievable by using compounding of flavor ingredients.
Reducing groups can be found on reducing sugars (sugar donors) and amino groups can be found on amino donors such as free amino acids, peptides, and proteins. Initially, a reactive carbonyl group of a reducing sugar condenses with a free amino group, with a concomitant loss of a water molecule. A reducing sugar substrate for Maillard reaction typically has a reactive carbonyl group in the form of a free aldehyde or a free ketone. The resultant N-substituted glycoaldosylamine is not stable. The aldosylamine compound rearranges, through an Amadori rearrangement, to form a ketosamine. Ketosamines that are so-formed may further react through any of the following three pathways: (a) further dehydration to form reductones and dehydroreductones; (b) hydrolytic fission to form short chain products, such as diacetyl, acetol, pyruvaldehyde, and the like, which can, in turn, undergo Strecker degradation with additional amino groups to form aldehydes, and condensation, to form aldols; and (c) loss of water molecules, followed by reaction with additional amino groups and water, followed by condensation and/or polymerization into melanoids. Factors that affect the rate and/or extent of Maillard reactions include among others the temperature, water activity, and pH. The Maillard reaction is enhanced by high temperature, low moisture levels, and alkaline pH.
In the Maillard reaction, suitable carbonyl containing reactants include those that comprise a reactive aldehyde (--CHO) or keto (--CO--) group, such that the carbonyl free aldehyde or free keto group is available to react with an amino group associated with the reactant. Typically, the reducing reactant is a reducing sugar, e.g., a sugar that can reduce a test reagent, e.g., can reduce Cu2+ to Cu+, or can be oxidized by such reagents.
Monosaccharides, disaccharides, oligosaccharides, polysaccharides (e.g., dextrins, starches, and edible gums) and their hydrolysis products are suitable reducing reactants if they have at least one reducing group that can participate in a Maillard reaction. Reducing sugars include aldoses or ketoses such as glucose, fructose, maltose, lactose, glyceraldehyde, dihydroxyacetone, arabinose, xylose, ribose, mannose, erythrose, threose, and galactose. Other reducing reactants include uronic acids (e.g., glucuronic acid, glucuronolactone, and galacturonic acid, mannuronic acid, iduronic acid) or Maillard reaction intermediates bearing at least one carbonyl group such as aldehydes, ketones, alpha-hydroxycarbonyl or dicarbonyl compounds.
In some embodiments, the present application provides a Maillard reaction product (MRP) composition that is formed from heating a reaction mixture comprising (1) a SG and/or GSG and (2) one or more amine donors. In some embodiments, the reaction mixture further comprises (3) one or more sugar donors.
The amine donor can be any compound or substance that contains a free amino group and that can participate in a Maillard reaction. Amine containing reactants include amino acids, peptides (including dipeptides, tripeptides, and oligopeptides), proteins, proteolytic or nonenzymatic digests thereof, and other compounds that react with reducing sugars and similar compounds in a Maillard reaction, such as phospholipids, chitosan, lipids, etc. In some embodiments, the amine donor also provides one or more sulfur-containing groups. Exemplary amine donors include amino acids, peptides, proteins, protein extracts.
Exemplary amino acids include, for example, nonpolar amino acids, such as alanine, glycine, isoleucine, leucine, methionine, tryptophan, phenylalanine, proline, valine; polar amino acids, such as cysteine, serine, threonine, tyrosine, asparagine, and glutamine; polar basic (positively charged) amino acids, such as histidine and lysine; and polar acidic (negatively charged) amino acids, such as aspartate and glutamate.
Exemplary peptides include, for example, hydrolyzed vegetable proteins (HVPs) and mixtures thereof.
Exemplary proteins include, for example, sweet taste-modifying proteins, soy protein, sodium caseinate, whey protein, wheat gluten or mixtures thereof. Exemplary sweet taste-modifying proteins include, for example, thaumatin, monellin, brazzein, miraculin, curculin, pentadin, mabinlin, and mixtures thereof. In certain embodiments, the sweet-taste modifying proteins may be used interchangeably with the term “sweetener enhancer.”
Exemplary protein extracts include yeast extracts, plant extracts, bacterial extracts and the like.
The nature of the amino donor can play an important role in accounting for the many flavors produced from a Maillard reaction. In some embodiments, the amine donor may account for one or more flavors produced from a Maillard reaction. In some embodiments, a flavor may be produced from a Maillard reaction by using one or more amine donors, or a particular combination of an amine donor and sugar donor.
In certain embodiments, the amine donor is present in the compositions described herein in a range of from about 1 to about 99 weight percent, from about 1 to about 50 weight percent, from about 1 to about 10 weight percent, from about 2 to about 9 weight percent, from about 3 to about 8 weight percent, from about 4 to about 7 weight percent, from about 5 to about 6 weight percent and all values and ranges encompassed over the range of from about 1 to about 50 weight percent. In some embodiments, the amine donor is from a plant source, such as vegetable juice, fruit juice, berry juice, etc.
In some embodiments, the sugar donor is a reducing sugar. Reducing sugars for use in the present application include, for example, all monosaccharides and some disaccharides, which can be aldose reducing sugars or ketose reducing sugars. Typically, the reducing sugar may be selected from the group consisting of aldotetrose, aldopentose, aldohexose, ketotetrose, ketopentose, and ketohexose reducing sugars. Suitable examples of aldose reducing sugars include erythrose, threose, ribose, arabinose, xylose, lyxose, allose, altrose, glucose, mannose, gulose, idose, galactose and talose. Suitable examples of ketose reducing sugars include erythrulose, ribulose, xylulose, psicose, fructose, sorbose and tagatose. The aldose or the ketose may also be a deoxy-reducing sugar, for example, a 6-deoxy reducing sugar, such as fucose or rhamnose.
Specific monosaccharide aldoses include, for example, reducing agents include, for example, where at least one reducing sugar is a monosaccharide, or the one or more reducing sugars are selected from a group comprising monosaccharide reducing sugars, typically at least one monosaccharide reducing sugar is an aldose or a ketose.
Where the reducing sugar is a monosaccharide, the monosaccharide may be in the D- or L-configuration, or a mixture thereof. Typically, the monosaccharide is present in the configuration in which it most commonly occurs in nature. For example, the one or more reducing sugars may be selected from the group consisting of D-ribose, L-arabinose, D-xylose, D-lyxose, D-glucose, D-mannose, D-galactose, D-psicose, D-fructose, L-fucose and L-rhamnose. In a more particular embodiment, the one or more reducing sugars are selected from the group consisting of D-xylose, D-glucose, D-mannose, D-galactose, L-rhamnose and lactose.
Specific reducing sugars include ribose, glucose, fructose, maltose, lyxose, galactose, mannose, arabinose, xylose, rhamnose, rutinose, lactose, maltose, cellobiose, glucuronolactone, glucuronic acid, D-allose, D-psicose, xylitol, allulose, melezitose, D-tagatose, D-altrose, D-alditol, L-gulose, L-sorbose, D-talitol, inulin, stachyose, including mixtures and derivatives therefrom.
Exemplary disaccharide reducing sugars for use in the present application include maltose, lactose, lactulose, cellubiose, kojibiose, nigerose, sophorose, laminarbiose, gentiobiose, turanose, maltulose, palantinose, gentiobiulose, mannobiose, melibiose, melibiulose, rutinose, rutinulose or xylobiose.
Mannose and glucuronolactone or glucuronic acid can be used as sugar donors under Maillard reaction conditions, although they have seldom been used. Maillard reaction products of mannose, glucuronolactone or glucuronic acid provide yet another unique approach to provide new taste profiles with the sweetener agents described throughout the specification alone or in combination with additional natural sweeteners, synthetic sweeteners, and/or flavoring agents described herein.
In some embodiments, one or more carbohydrate sweeteners may be added to a reaction mixture subjected to the Maillard reaction. In other embodiments, one or more carbohydrate sweeteners may be added to an MRP composition after Maillard reaction. Non-limiting examples of carbohydrate sweeteners for use in the present application include caloric sweeteners, such as, sucrose, fructose, glucose, D-tagatose, trehalose, galactose, rhamnose, cyclodextrin (e.g., α-cyclodextrin, β-cyclodextrin, and γ-cyclodextrin), ribulose, threose, arabinose, xylose, lyxose, allose, altrose, mannose, idose, lactose, maltose, invert sugar, isotrehalose, neotrehalose, palatinose or isomaltulose, erythrose, deoxyribose, gulose, idose, talose, erythrulose, xylulose, psicose, turanose, cellobiose, glucosamine, mannosamine, fucose, glucuronic acid, gluconic acid, glucono-lactone, abequose, galactosamine, sugar alcohols, such as erythritol, xylitol, mannitol, sorbitol, maltitol, lactitol, mannitol, and inositol; xylo-oligosaccharides (xylotriose, xylobiose and the like), gentio-oligoscaccharides (gentiobiose, gentiotriose, gentiotetraose and the like), galacto-oligosaccharides, sorbose, nigero-oligosaccharides, fructooligosaccharides (kestose, nystose and the like), maltotetraol, maltotriol, malto-oligosaccharides (maltotriose, maltotetraose, maltopentaose, maltohexaose, maltoheptaose and the like), lactulose, melibiose, raffinose, rhamnose, ribose, isomerized liquid sugars such as high fructose corn/starch syrup (containing fructose and glucose, e.g., HFCS55, HFCS42, or HFCS90), coupling sugars, soybean oligosaccharides, and glucose syrup. Additionally, the above carbohydrates may be in either the D- or L-configuration.
It should be noted, however, that not all carbohydrate sweeteners are reducing sugars. Sugars having acetal or ketal linkages are not reducing sugars, as they do not have free aldehyde chains. They therefore do not react with reducing-sugar test solutions (e.g., in a Tollens’ test or Benedict’s test). However, a non-reducing sugar can be hydrolyzed using diluted hydrochloric acid.
In some embodiments, the sugar donor is a non-reducing sugar that does not contain free aldehyde or free keto groups. Exemplary non-reducing sugars include, but are not limited to, sucrose, trehalose, xylitol, and raffinose. In some embodiments, the sugar donor comprises both reducing sugar and non-reducing sugar. In some embodiments, the sugar donor is derived from a food ingredient, such as sugar, flour, starch, vegetable and fruits.
In some embodiments, the sugar donor is derived from a plant source. For example, in some embodiments, the sugar donor comprises a fruit juice, berry juice, vegetable juice, syrup, plant extract, vegetable extract etc.
In some embodiments, the sugar donor is orange juice, cranberry juice, apple juice, peach juice, watermelon juice, pineapple juice, grape juice and concentrated products thereof.
In some embodiments, the fruit juice, berry juice or vegetable juice serves as both amine donor and sugar donor.
Reducing sugars can be derived from various sources for use as sugar donors in the Maillard reaction. For example, a sugar syrup may be extracted from a natural source, such as Monk fruit, fruit juice or juice concentrate (e.g., grape juice, apple juice, etc.), vegetable juice (e.g., onion etc.), or fruit (e.g., apples, pears, cherries, etc.) for use as a sugar donor.
The syrup may include any type of juice regardless of whether there is any ingredient being isolated from juice, such as purified apple juice with trace amounts of malic acid etc. The juice can be in the form of liquid, paste or solid. Sugar donors may also be extracted from Stevia, sweet tea, luohanguo, etc. after isolation of high intensity sweetener agents described herein (containing non-reducing sugars) from crude extracts and mixtures thereof. Extracts from any part of plant containing reducing sugars can be used as sugar donors in Maillard reactions with or without other additional reducing sugars. In some embodiments, the MRPs are prepared using a plant extract as a sugar donor.
In some embodiments, the sugar donor and amino donor are present in the reaction mixture in a molar ratio of 10:1 to 1:10, 8:1 to 1:8, 6:1 to 1:6, 4:1 to 1:4, 3:1 to 1:3 or 2:1 to 1:2.

Maillard reaction(s) can be conducted either under open or sealed conditions. The reaction time is generally from 1 second to 100 hours, more particularly from 1 minute to 24 hours, from 1 minute to 12 hours, from 1 minute to 8 hours, from 1 minute to 4 hours, from 1 minute to 2 hours, from 1 minute to 1 hour, from 1 minute to 40 minutes, from 1 minute to 20 minutes, from 1 minute to 10 minutes, from 10 minutes to 24 hours, from 10 minutes to 12 hours, from 10 minutes to 8 hours, from 10 minutes to 4 hours, from 10 minutes to 2 hours, from 10 minutes to 1 hour, from 10 minutes to 40 minutes, from 10 minutes to 20 minutes, from 20 minutes to 24 hours, from 20 minutes to 12 hours, from 20 minutes to 8 hours, from 20 minutes to 4 hours, from 20 minutes to 2 hours, from 20 minutes to 1 hour, from 20 minutes to 40 minutes, from 40 minutes to 24 hours, from 40 minutes to 12 hours, from 40 minutes to 8 hours, from 40 minutes to 4 hours, from 40 minutes to 2 hours, from 40 minutes to 1 hour, from 1 hour to 24 hours, from 1 hour to 12 hours, from 1 hour to 8 hours, from 1 hour to 4 hours, from 1 hour to 2 hours, from 2 hour to 24 hours, from 2 hour to 12 hours, from 2 hour to 8 hours, from 2 hour to 4 hours, from 4 hour to 24 hours, from 4 hour to 12 hours, from 4 hour to 8 hours, from 8 hour to 24 hours, from 8 hour to 12 hours, or from 12 hour to 24 hours. Depending on the desired taste, the reaction can be terminated at any time. The Maillard reaction mixture can contain unreacted reactants, degraded substances from the reactants, pH regulator(s), and/or salt(s).
The Maillard reactions can be conducted at atmospheric pressure or under pressure. When conducted under pressure, the reaction mixture may be subjected to constant pressure or it may be subjected to varying pressures over time. In certain embodiments, the pressure in the reaction vessel is at least 10 MPa, at least 20 MPa, at least 30 MPa, at least 40 MPa, at least 50 MPa, at least 75 MPa, at least 100 MPa, at least 150 MPa, at least 200 MPa, at least 250 MPa, at least 300 MPa, at least 400 MPa, at least 500 MPa, at least 600 MPa, at least 700 MPa, at least 800 MPa, and any pressure range derived from the aforementioned pressure values.
In some embodiments, the Maillard reaction is conducted with the assistance of microwave heating. Microwave heating results in the superheating of substances, particularly those that response to dipole rotation or ionic conductivity.
In some embodiments, it is desirable to suppress the Maillard reaction, in part. This can be achieved by exercising one or more of the following approaches, including the use of raw materials that are not susceptible to browning, adjusting the factors affecting the browning velocity of Maillard reaction, lowering the temperature, lowering pH, adjusting water activity, increasing the level of oxygen, using oxidant, introducing enzymes, etc.
In certain embodiments, the use of low solubility or insoluble amino acids in the Maillard reaction may result in insoluble reactants present in the final MRP composition. In such cases, filtration may be used to remove any insoluble components present in the MRP compositions.
A general method to prepare derived Maillard reaction product(s) is described as follows. Briefly, a steviol glycoside composition of the present application, such as RA or hpRA, or a glycosylated steviol glycoside composition of the present application, such as GRA or G-hpRA, is dissolved with or without a sugar donor, and together with amino acid donor in a solvent, such as water, to form a reaction mixture, followed by heating of the reaction mixture at an elevated temperature, for example, from 30, 40, or 50° C. up to 250° C. The reaction time can be varied from more than one minute to a few days, more generally a few hours, until Maillard reaction products (MRPs) are formed or one of the reaction components has been exhausted or the reaction has been completed, with or without formation of caramelization reaction products (CRPs), which are further described below. When required, a pH adjuster or pH buffer can be added to regulate the pH of the reaction mixture before, during or after reaction as further described herein. The resultant solution is dried by spray dryer or hot air oven to remove the water and to obtain the MRP composition of the present application.
When the reaction is completed, the product mixture does not need to be neutralized or it can be neutralized. Water and/or solvent(s) do not necessarily need to be removed but can be removed by distillation, spray drying or other known methods if the product is desired as a powder or liquid, whatever the case may be.
Interestingly, when a reaction mixture is dried to a powder, such as by spray drying, the resultant powder typically only has a slight smell associated with them. This is in contrast to regular powdered flavoring agents that generally have a strong smell. The dried powdered reaction mixtures of the embodiments, when dissolved in a solvent, such as water or alcohol or mixtures thereof, release the smell. This demonstrates that the volatile substances in the MRP can be preserved by the SG or GSG present in the MRP composition of the present application. Powders with strong aromas can be obtained too, particularly where the carrier, such as RA or GRA, is much less compared with MRP flavors or strong flavor substances used during Maillard reactions.
In some embodiments, the MRP composition may further include one or more carriers (or flavor carriers) acceptable for use with sweetener agents or flavoring agents. In addition, such carriers may be suitable e.g., as solvents for the Maillard reaction.
Exemplary carriers include acetylated distarch adipate, acetylated distarch phosphate, agar, alginic acid, beeswax, beta-cyclodextrine, calcium carbonate, calcium silicate, calcium sulphate, candelilla wax, carboxymethyl cellulose, sodium salt, carnauba wax, carrageenan, microcrystalline cellulose, dextran, dextrin, diammonium phosphate, distarch phosphate, edible fats, elemi resin, ethyl lactate, ethyl cellulose, ethyl hydroxyethyl cellulose, ethyl tartrate, gelatin, gellan gum, ghatti gum, glucose, glyceryl diacetate, glyceryl diesters of aliphatic fatty acids C6-C18, glyceryl monoesters of aliphatic fatty acids C6-C18, gyceryl triacetate (triacetin), glyceryl triesters of aliphatic fatty acids C6-C18, glyceryl tripropanoate, guar gum, gum arabic, hydrolyzed vegetable protein, hydroxyproplymethyl cellulose, hydroxypropyl cellulose, hydroxypropyl distarch phosphate, hydroxypropyl starch, karaya gum, konjac gum, lactic acid, lactose, locust bean gum (carob bean gum), magnesium carbonate, magnesium salts of fatty acids, maltodextrin, methyl cellulose, medium chain triglyceride, modified starches, such as acetylated distarch adipate, acetylated oxidized starch, acid-treated starch, alkaline treated starch, bleached starch, roasted starch dextrins, distarch phosphate, hydroxypropyl distarch phosphate, acetylated distarch phosphate, hydroxypropyl starch, monostarch phosphate, oxidized starch, phosphated distarch phosphate, starch acetate, starch sodium octenyl succinate, and enzyme treated starches; mono-,di- and tri-calcium orthophosphate, Na, K, NH4 and Ca alginate, pectins, processed euchema seaweed, propylene glycol alginate, sodium chloride (salt), silicon dioxide, sodium aluminium diphosphate, sodium aluminium silicate, Sodium, potassium and calcium salts of fatty acids, starch, starch (sodium) octenyl succinate, starch acetate, sucro glycerides, sucrose, sucrose esters of fatty acids, type I and type II sucrose oligoesters, taragum, tragacanth, triethylcitrate, whey powder, xanthan gum, fibers such as non-starch polysaccharides, lignin, cellulose, methylcellulose, the hemicelluloses, β-glucans, mucilage, inulins, oligosaccharides, polydextrose, fructooligosaccharides, cyclodextrins, chitins, and combinations thereof, and thickeners such as carbomers, cellulose base materials, gums, waxes, algin, agar, pectins, carrageenan, gelatin, mineral or modified mineral thickeners, polyethylene glycol and polyalcohols, polyacrylamide and other polymeric thickeners, and combinations thereof.
When utilizing the MRP compositions for use in a sweetener or flavoring composition, one or more additional components may be added to the MRP composition after the Maillard reaction has occurred. In some embodiments, these additional components include flavoring substances. Moreover, the reaction products after the Maillard reaction has been completed can further include, for example, one or more sweetener agents, reducing sugars (i.e., residue sugar donors), amine donors, sweetener enhancers, and CRPs, as well as one or more degraded sweetener agents, degraded sugar donors, degraded amine donors, and salts.
It should also be understood, for example, that the Maillard reaction can be performed under conditions containing an excess of amine donors in comparison to reducing sugars or much less than the amount of reducing sugars present. In the first instance, the resultant MRPs would include unreacted amine donors, degraded amine donors and/or residues from reacted amine donors. Conversely, when there is an excess of reducing sugars present in the Maillard reaction, the amine donors would be more fully reacted during the course of the reaction and a greater amount of unreacted reducing sugars as well as degraded reducing sugars and/or degrading reducing sugars and residues therefrom. Surprisingly, where the reducing sugar is replaced with a sweetener agent (e.g., a material such as an RA that does not include a reactive aldehydic or ketone moiety) and reacted with one or more amine donors, the amine donors may be present in the reaction products in reduced amounts reflecting their consumption in the Maillard type reaction or there excess of amine donors, as well as amine donor residues and/or amine degradation products after the Maillard reaction has been completed.
There are many ways to control the resulting MRP composition. For instance, adjusting the pH, pressure, reaction time, and ingredient additions to optimize the ratio of raw materials etc. Further, the separation of Maillard reaction products can provide a means for preparing different types of flavors or flavor enhancers. For example, a Maillard reaction product composition includes both volatile substances and non-volatile substances. Therefore, by evaporating the volatile substances, non-volatile substances can be purified for use. These non-volatile substances (or products) can be used as flavor modifiers or with the top note flavor in final products, such as volatile peach, lemon flavor provided by traditional flavor houses.
Volatile substances can be used as flavor or flavor enhancers as well. Partial separation/purification of a MRP can be carried out to obtain volatile substances, which can be further separated by distillation etc. or obtain non-volatile substances for instance by recrystallization, chromatograph etc. could be done to meet different targets of taste and flavor. Therefore, the MRP compositions of the present application include compositions containing one or more volatile substances, one or more non-volatile substances or mixtures thereof. Non-volatile substances in MRPs or isolated from MRPs can provide a good mouth feel, umami and Kokumi taste.
In some embodiments, the sweetener or flavoring composition of the present application further comprises a MRP formed from a reaction mixture comprising one or more flavonoid glycosides, isoflavone glycosides, saponin glycosides, phenol glycosides, cynophore glycosides, anthraquinone glycosides, cardiac glycosides, bitter glycosides, coumarin glycosides, and/or sulfur glycosides.

In some embodiments, the sugar donor may account for one or more flavors produced from a Maillard reaction. More particularly, a flavor may be produced from a Maillard reaction by using one or more sugar donors, wherein at least one sugar donor is selected from a product comprising a glycoside and a free carbonyl group. In some embodiments, glycosidic materials for use in Maillard reactions include natural juice/concentrates/extracts selected from strawberry, blueberry, blackberry, bilberry, raspberry, lingonberry, cranberry, red currants, white currants, blackcurrants, apple, peach, pear, apricot, mango, grape, water melon, cantolope, grapefruit, passion fruit, dragon fruit, carrot, celery, eggplant, tomato, etc.

Alternatively, a root or berry juice may be used as sugar donor or sweetener added to an MRP composition.
In some embodiments, particular flavors may be produced from a Maillard reaction through the use of one or more sugar donors, where at least one sugar donor is selected from plant juice/powder, vegetable juice/powder, berries juice/powder, fruit juice/powder. In certain preferred embodiments, a concentrate or extract may be used, such as a bilberry juice concentrate or extract having an abundance of anthocyanins. Optionally, at least one sugar donor and/or one amine donor is selected from animal source based products, such as meat, oil etc. Meat from any part of an animal, or protein(s) from any part of a plant could be used as source of amino donor(s) in this application.
In some embodiments, the Maillard reactants may further include one or more high intensity synthetic sweeteners, natural non-SG sweeteners, and/or the glycosylation products thereof. Alternatively, or in addition, the high intensity synthetic sweeteners may be added to an MRP composition comprising reaction products formed in the Maillard reaction.
Caramelization can occur in the course of Maillard reaction. Exemplary reactions include:
One embodiment comprises one or more of these non-volatile substances originating from the MRP of the present application, including remaining sugar donors, remaining amine donors, and caramelized substances thereof. The caramelized substances can include e.g., caramelized disaccharides, trisaccharides, tetrasaccharides etc., which are formed by sugar donors; dimer-peptides, tri-peptides, tetra-peptides etc., which are formed by amine donors; glycosylamine and their derivatives, such as Amadori compounds, Heyns compounds, enolisated compounds, sugar fragments, amino acid fragments, and non-volatile flavor compounds formed by Maillard reactions of sugars and amino acid donors.
In some embodiments, a desirable MRP or a glycosylated amine donor is prepared by precision fermentation. Precision fermentation technology is a form of synthetic biology that typically requires the use of genetically engineered microorganisms. The genetically engineered microorganisms, such as yeast, algae or bacteria, are capable of producing or excreting a particular desirable material, such as edible fats, proteins and glycosylated amines donors. In some embodiments, glycosylated conventional amine donors, glycosylated natural high intensity sweeteners, glycosylated stevia extracts, glycosylated SGs, glycosylated sweet tea extracts, or glycosylated monk fruit extracts, are produced by precision fermentation. In some embodiments, the C-MRPs, SG-MRPs or GSG-MRPs of the present application are produced by precision fermentation.

There are four conventional basic tastes: sweet, sour salty, and bitter. Discovery of taste receptors specific for umami made academic society accepted umami as basic taste. However, it is still in dispute on how to categorize new tastes such as kukumi, fat, metallic and carbohydrate tastes. The inventor surprisingly found that non-volatile substances, such as sugar, sodium glutamate, carbohydrate, salt etc., can be carried by oral aerosol into nasal cavity, and that nasal cavity may play an important role for sensing the quality of food and beverage.
In the past, sensation and perception of umami, kukumi, carbohydrate and fat by single compound was measured without considering evolution of human’s adoption to these tastes. The inventors believe all these new tastes are evolving sensations based on a many factors, such as the cooking and/or fermentation conditions for food/beverage, the temperature at which the food/beverage is served, and enzyme activity in tester’s saliva, especially the activity of those enzymes that may hydrolyze macronutrients such as meat, fat, and starch. Therefore, it is necessary to consider the overall sensation and perception of meat, fat and starch. Protein in meat could be hydrolyzed into certain sweet amino acid, fat could be hydrolyzed into glycerol, starch could be hydrolyzed into mono and oligosaccharides. So taste wise, perception of meat, fat and starch may be classified as sweet taste. However, human overall perception of starch, meat and fat are obtained mainly from cooked foods, it is less meaningful to talk about taste only without taking aroma and mouthfeel into consideration. Retronasal cavity was evolved after human mastered the technology to manipulate fire. Human is the only species on earth to use fire. Framing and livestock domestication allowed humans to substantiaHy augment the food they obtained from hunting and gathering. Humans also know how to obtain salt around 8,000 years ago. So evolution of retronasal cavity was accelerated after humans mastered the knowledge of cooking with fire, domesticating plants and animals, and adding salt to food. The evolved retronasal cavity plays the important role to identify the hedonic level of foods which could bring the pleasure and activate the rewarding system.
The inventors found that retronasal cavity is the first place for humans to integrate the overall taste, mouthfeel and aroma originated from food and beverage. The overall perception of starch, meat and fat are integrated flavor. Starch, meat and fat have less taste but significant sensation of mouthfeel with mailard reaction flavors. Naturally, tastes of these substances should not be taken as basic taste, but should be classified as retronasal sensation and perception, neither basic tastes in mouth cavity, nor alimentary tastes in gastrointestinal tract. Umami taste should not be taken as basic taste but should be re-categorized as a sub-taste of retronasal sensation. Due to differences in biology, mechanism and function of sensation, retronasal sensation deserves an independent position from oral sensation and orthonasal olfactory sensation. So overall oral and olfactory sensation could be classified as 1) basic tastes including sweet, sour, bitter, salt; 2) supplementary cooked sensation or retronasal sensations including umami, kukumi, starch, fat, metallic sensation etc., and 3) orthonasal olfactory smell. Since retronasal cavity plays important role in sensing basic tastes, retronasal cavity could be taken as extended or supplementary areas for basic tastes in oral cavity. An embodiment of sweetening or flavor composition comprises one or more substances selected from high intensity sweeteners, hydrolyzed starch, starch, amino acid, hydrolyzed protein either from plant or animal source, protein either from plant or animal source, glycerol, hydrolyzed fat, fat either from plant or animal source.
The inventors believe that perception of chemical sensation is not simply mediated by taste receptors. The inventors hypothesized that tastants could be sensed by olfactory bulb together with aroma. Olfactory bulb rates the substances in mouth by level of harmlessness, not by the taste character. So process of sensory information could be accelerated in order to get quick decision whether the food is toxic or not, eatable or not.
Unlike conventional knowledge that perception of taste sensation is resulted by unidirectional transmitted from taste receptors in mouth cavity to brain, the inventors found that expectation in brain plays important role to regulate the overall physiological condition when tasting. Therefore, it is necessary to take consumers’ expectation of time intensity profile of sugar and physiological effect of sugar such as acting rewarding system into consideration when developing sugar reduced formulation. Of course, consumers in different regions have different expectation for food and beverage based on their traditional diets and culture.
The inventors also found that perception of food and beverage is a cognitive decision and follows expected goal-direct manner. Individual sensation is defined as a human’s capability to process, interpret, encode, manipulate, and access to individual tastant’s information so as to acquire, retain, and apply experience from memory in brain quickly and successfully to assess the value of a particular tastant. Organizational overall sensation is an organization’s capability to process, interpret, encode, manipulate, and access to overall taste, mouthfeel and aroma information of a food or beverage in a purposeful, goal-directed manner, so it can increase human’s adaptive potential in the environment in which it operates.
The inventors belivev that, in addition to the hierarchical transmission of sensory information by individual sense and final integration of all senses in brain, there are more connections among all senses within organizational sensation system, such as aggregation, cross-level, and distribution etc. based on different level of cognitive decision.
Taste receptors for different tastes distributed in oral and retronasal cavity could be counted. There are limited taste receptors for high intensity sweeteners. Different type of high intensity sweeteners have different affinities to specific sweet taste receptors. Therefore, there is ceiling of saturation for sweeteners to bind these taste receptors. For example, taste of synthetic sweeteners such as sucralose, and natural sweeteners such as stevia have uplimit sweet level with good taste not more than 6 SugarE, preferably less than 5 SugarE. There is need to look for different combination of high intensity sweeteners in order to have good sweet taste profile to realize full sugar reduction for higher sweetness level such as 10 SugarE.
Perception is a kind of trained skill. Perception is a continually dynamic process of minimizing error of prediction based on experience in memory. Perception is a kind of decision-making about how to categorize the contextual sensory information, refine the difference between top-down prediction and bottom-up sensation, then form a value judgement in an integrated manner. So perception is the process that our brain is trying hard to make best guesses about the attentive causes among noisy and ambiguous sensory signals. Perception should not be taken as a given sensation presented by stimuli. In fact, brain is actively shaping the attentive sensory information by experience in mind.
Perception is not a kind of reconstruction of sensory input in brain like a mirror. Process of perception in brain contains three core elements: generating predictive model, sensing via sensory organization, and refining comparison of the precisive weighting of sensory signals with predictive model. In other words, process of perception includes three events: we already know (the prior in memory), what we should believe next (the posterior by prediction), and what we are sensing now (the likelihood by associative context). So perception is a course of prediction error minimization, rather than a result of stimulation by sensory signals initiated by stimuli.
Generation of prediction is normally highly related to extrinsic components such as visional sensation of food and beverage associated with experience in memory and priming context. Therefore, integrated formlator of ingredients and marketing department at beginning of designing formulation is very important. The precising visual information could help the consumers to make a better prediction. Meanwhile, unlike static snapshot, perception is a kind of rolling process, The relevant priming sensory information is the key to provide the cause to make the brain’s prediction more precisely. Human being is evolved to save the energy. the consistent of relevant sensory information would help to shorten the time of making judgement by brain.
So eventually, perception is an algorithm that brain is searching similarity between the input sensory signals and predictive model in memory. Memory of food is combination of declarative and non-declarative long-term memory. The process of flavor perception is similar to visual sensation. There are contextual building blocks.
For example, fruit flavors are recognition of fruits in brain, tasting fruit is holistic contextual sensation with clear sequences. Volatile substances like conventional orthonasal smell are elements for outer controur of overall flavor, and substances including non-volatile tastants like sugar provide relevant context to brain to build the confident on the prediction of flavor.
Context sensory information in food beverage provide important information to improving accuracy of flavor prediction. Context information includes relevant familiar unconscious sensory signals, sequence and speed of different sensory information. Vivid attentive context could lead to more rapid and more accurate conscious perception. Good design of a food or beverage is not to let the brain to reshape the expectation frequently but make all clues of sensory signals as close as possible to the predicted perception.
Unlike sugar, context provided to brain by high intensity sweeteners such as sucralose and stevia are incomplete, uncertain, ambiguous, which make the perceived information very difficult to be classified when compared with expected sugar-like sweet perception. For example, unexpected slow onset sweetness makes the perceiving in brain slow and difficult because it changes the predicted sensory sequence and consequence action of flavor. Quick onset is important, because the more familiar and easy to be identified and recognized unconscious and conscious signals are more distinguishable than other un-familiar, difficult ones. The perceptual prediction of a flavor provided by vision and context are able to alter sensory activity at early stage of taste processing in a way that enhances the perception. So matching the priming context of perceptual expectations improve the guess accuracy of predicted perception to actual conscious sensation. Surely, the best experience would be the sensory signals provided by stimuli could perfectly match the overall predicted perception in every aspect. Unfortunately, overwhelming unfamiliar sensory signals of high intensity sweeteners make the sugar predicted guess take long time to change itself to match the reality of sweetness perception of high intensity sweeteners, and eventually realize it is different and it is unfamiliar.
Consistence of relevant sensory information provided by stimuli is important for prediction error minimization. Sensory signals provided by high intensity sweeteners such as slow onset, bitter, metallic, lingering attributes could be classified as low estimated precision data, which have a weak effect on associating with rooted sweetness perception immersed by sugar. So modifying these unfamiliar or unpleasant attributes of high intensity sweeteners could improve the success of brain’s predicted perception.
Increasing the estimated precision of sensory signals is nothing other than making brain have no or less attention to unfamiliar signals. The current invention helps to build similarly of flavor in food and beverage compared with fresh prepared foods. It provides a solution to make the premises of predicted sugar-like sweetness perception are true and correct, then brain’s deductive prediction could be guaranteed to be correct. The current invention provides a solution to improve the authenticity of flavor including sweetness, mouthfeel and aroma in food and beverage either sweetened by conventional sweeteners or high intensity sweeteners, thus the flavor could be quickly associated with memory, recognized by brain and categorized in brain.
Plasticity of memory in brain is like water, could be formed in millions form as per wish. It is not rigid. Water-like information stored in overall body nerves could be recalled and gather together immediately to form prediction model for sensory process. Purpose of the flavor is to distinguish food. Quick recognition and fast categorization are the skills by evolution. Ambiguous information makes slow recognition which costs a lot of energy and brain is reluctant to do such job. An embodiment of a food or beverage comprises composition in current invention, which provides a method to use unconscious tastants as flavor to block and mask conscious unpleasant and influencing sensory noises to brain, thus provide brain the predicted events: what, when, how fast and in what sequence of sensory signals go to brain.

The compositions and methods described herein are useful in a wide range of consumable products. A non-limiting outline of products for application of the compositions described herein includes the following:
In one aspect, the present application provides an orally consumable product comprising the composition of the present application described herein. The term “consumables”, as used herein, refers to substances which are contacted with the mouths of people or animals, including substances, which are taken into and subsequently ejected from the mouth, substances which are drunk, eaten, swallowed or otherwise ingested, and are safe for human or animal consumption when used in a generally acceptable range.
The compositions of the present application can be added to an orally consumable product to provide a sweetened product or a flavored product. The compositions of the present application can be incorporated into any oral consumable product, including but not limited to, for example, beverages and beverage products, food products or foodstuffs (e.g., confections, condiments, baked goods, cereal compositions, dairy products, chewing compositions, and tabletop sweetener compositions), pharmaceutical compositions, smoking compositions, oral hygiene compositions, dental compositions, and the like. Consumables can be sweetened or unsweetened. Consumables employing the compositions of the present application are also suitable for use in processed agricultural products, livestock products or seafood; processed meat products such as sausage and the like; retort food products, pickles, preserves boiled in soy sauce, delicacies, side dishes; soups; snacks, such as potato chips, cookies, or the like; as shredded filler, leaf, stem, stalk, homogenized leaf cured and animal feed.
In some embodiments, a beverage or beverage product comprises a composition of the present application. The beverage may be sweetened or unsweetened. The composition of the present application, or sweetener composition comprising the same, may be added to a beverage to sweeten the beverage or to regulate a cooling effect.
A “beverage” or “beverage product,” is used herein with reference to a ready-to-drink beverage, beverage concentrate, beverage syrup, or powdered beverage. Suitable ready-to-drink beverages include carbonated and non-carbonated beverages. Carbonated beverages include, but are not limited to, frozen carbonated beverages, enhanced sparkling beverages, cola, fruit-flavored sparkling beverages (e.g., lemon-lime, orange, grape, strawberry and pineapple), ginger-ale, soft drinks and root beer. Non-carbonated beverages include, but are not limited to, fruit juice, fruit-flavored juice, juice drinks, nectars, vegetable juice, vegetable-flavored juice, sports drinks, energy drinks, enhanced water drinks, enhanced water with vitamins, near water drinks (e.g., water with natural or synthetic flavorants), coconut water, tea type drinks (e.g., black tea, green tea, red tea, oolong tea), coffee, cocoa drink, broths, beverages comprising milk components (e.g., milk beverages, coffee comprising milk components, cafe au lait, milk tea, fruit milk beverages), beverages comprising cereal extracts, and smoothies. Beverages may be frozen, semi-frozen (“slush”), non-frozen, ready-to-drink, concentrated (powdered, frozen, or syrup), dairy, non-dairy, probiotics, prebiotics, herbal, non-herbal, caffeinated, non-caffeinated, alcoholic, non-alcoholic, flavored, non-flavored, vegetable-based, fruit-based, root/tuber/corm-based, nut-based, other plant-based, cola-based, chocolate-based, meat-based, seafood-based, other animal-based, algae-based, calorie enhanced, calorie-reduced, and calorie-free.
The resulting beverages may be dispensed in open containers, cans, bottles or other packaging. Such beverages and beverage preparations can be in ready-to-drink, ready-to-cook, ready-to-mix, raw, or ingredient form and can use the composition as a sole sweetener or as a co-sweetener.
A significant challenge in the beverage industry is to preserve flavor in drinks. Normally, essential oils and their fractions are used as key flavors. They are prone to be oxidized to create unpleasant flavor(s) or the components easily evaporate to cause the food or beverage to lose their initial designed flavors as they sit on shelves. The embodiments herein provide new methods and compositions to overcome those disadvantages and provide new solutions to the food and flavor industry.
Compared with conventional flavors, which are mainly preserved in different oils or oil soluble solvents, the present embodiments provide new methods to provide water soluble solutions, syrups and powders for flavoring agents.
Compared to conventional isolated flavors, often as extracts from plant or animal sources, which are not always compatible for top note flavor and/or taste when sugar replacement sweeteners are added, the current embodiments provide new types of combined multi components which are compatible for a designed flavor.
The embodiments surprisingly create sugar reduced sweeteners which have better taste than sugar including, for example, sweetening agents from plants, such as Stevia, sweet tea, monk fruit, licorice etc., as well as synthetic sweeteners, such as sucralose.
Beverage concentrates and beverage syrups can be prepared with an initial volume of liquid matrix (e.g., water) and the desired beverage ingredients. Full strength beverages are then prepared by adding further volumes of water. Powdered beverages are prepared by dry-mixing all of the beverage ingredients in the absence of a liquid matrix. Full strength beverages are then prepared by adding the full volume of water.
Beverages comprise a matrix, i.e., the basic ingredient in which the ingredients - including the compositions of the present application - are dissolved. In one embodiment, a beverage comprises water of beverage quality as the matrix, such as, for example deionized water, distilled water, reverse osmosis water, carbon-treated water, purified water, demineralized water or combinations thereof, can be used. Additional suitable matrices include, but are not limited to phosphoric acid, phosphate buffer, citric acid, citrate buffer and carbon-treated water.

In some embodiments, the consumable product comprising one or more NHIS, one or more derivatives of NHIS, and/or one or more cooling agents is a chewing composition. The term “chewing compositions” include chewing gum compositions, chewing tobacco, smokeless tobacco, snuff, chewing gum and other compositions which are masticated and subsequently expectorated.
Chewing gum compositions generally comprise a water-soluble portion and a water-insoluble chewable gum base portion. The water soluble portion, which typically includes one or more components of the compositions of the present application, dissipates with a portion of the flavoring agent over a period of time during chewing while the insoluble gum base portion is retained in the mouth. The insoluble gum base generally determines whether a gum is considered chewing gum, bubble gum, or a functional gum.
The insoluble gum base, which is generally present in the chewing gum composition in an amount in the range of about 15 to about 35 weight percent of the chewing gum composition, generally comprises combinations of elastomers, softeners (plasticizers), emulsifiers, resins, and fillers. Such components generally are considered food grade, recognized as safe (GRA), and/or are U.S. Food and Drug Administration (FDA)-approved.
Elastomers, the primary component of the gum base, provide the rubbery, cohesive nature to gums and can include one or more natural rubbers (e.g., smoked latex, liquid latex, or guayule); natural gums (e.g., jelutong, perillo, sorva, massaranduba balata, massaranduba chocolate, nispero, rosindinha, chicle, and gutta hang kang); or synthetic elastomers (e.g., butadiene-styrene copolymers, isobutylene-isoprene copolymers, polybutadiene, polyisobutylene, and vinyl polymeric elastomers). In a particular embodiment, the elastomer is present in the gum base in an amount in the range of about 3 to about 50 weight percent of the gum base.
Resins are used to vary the firmness of the gum base and aid in softening the elastomer component of the gum base. Non-limiting examples of suitable resins include a rosin ester, a terpene resin (e.g., a terpene resin from α-pinene, β-pinene and/or D-limonene), polyvinyl acetate, polyvinyl alcohol, ethylene vinyl acetate, and vinyl acetate-vinyl laurate copolymers. Non-limiting examples of rosin esters include a glycerol ester of a partially hydrogenated rosin, a glycerol ester of a polymerized rosin, a glycerol ester of a partially dimerized rosin, a glycerol ester of rosin, a pentaerythritol ester of a partially hydrogenated rosin, a methyl ester of rosin, or a methyl ester of a partially hydrogenated rosin. In some embodiment, the resin is present in the gum base in an amount in the range of about 5 to about 75 weight percent of the gum base.
Softeners, which also are known as plasticizers, are used to modify the ease of chewing and/or mouth feel of the chewing gum composition. Generally, softeners comprise oils, fats, waxes, and emulsifiers. Non-limiting examples of oils and fats include tallow, hydrogenated tallow, large, hydrogenated or partially hydrogenated vegetable oils (e.g., soybean, canola, cottonseed, sunflower, palm, coconut, corn, safflower, or palm kernel oils), cocoa butter, glycerol monostearate, glycerol triacetate, glycerol abietate, lecithin, monoglycerides, diglycerides, triglycerides acetylated monoglycerides, and free fatty acids. Non-limiting examples of waxes include polypropylene/polyethylene/Fisher-Tropsch waxes, paraffin, and microcrystalline and natural waxes (e.g., candelilla, beeswax and carnauba). Microcrystalline waxes, especially those with a high degree of crystallinity and a high melting point, also may be considered as bodying agents or textural modifiers. In some embodiments, the softeners are present in the gum base in an amount in the range of about 0.5 to about 25 weight percent of the gum base.
Emulsifiers are used to form a uniform dispersion of the insoluble and soluble phases of the chewing gum composition and also have plasticizing properties. Suitable emulsifiers include glycerol monostearate (GMS), lecithin (phosphatidyl choline), polyglycerol polyricinoleic acid (PPGR), mono and diglycerides of fatty acids, glycerol distearate, tracetin, acetylated monoglyceride, glycerol triacetate, and magnesium stearate. In some embodiments, the emulsifiers are present in the gum base in an amount in the range of about 2 to about 30 weight percent of the gum base.
The chewing gum composition also may comprise adjuvants or fillers in either the gum base and/or the soluble portion of the chewing gum composition. Suitable adjuvants and fillers include lecithin, inulin, polydextrin, calcium carbonate, magnesium carbonate, magnesium silicate, ground limestone, aluminum hydroxide, aluminum silicate, talc, clay, alumina, titanium dioxide, and calcium phosphate. In some embodiments, lecithin can be used as an inert filler to decrease the stickiness of the chewing gum composition. In other some embodiments, lactic acid copolymers, proteins (e.g., gluten and/or zein) and/or guar can be used to create a gum that is more readily biodegradable. The adjuvants or fillers are generally present in the gum base in an amount up to about 20 weight percent of the gum base. Other optional ingredients include coloring agents, whiteners, preservatives, and flavors.
In some embodiments of the chewing gum composition, the gum base comprises about 5 to about 95 weight percent of the chewing gum composition, more desirably about 15 to about 50 weight percent of the chewing gum composition, and even more desirably from about 20 to about 30 weight percent of the chewing gum composition.
The soluble portion of the chewing gum composition may optionally include other artificial or natural sweeteners, bulk sweeteners, softeners, emulsifiers, flavoring agents, coloring agents, adjuvants, fillers, functional agents (e.g., pharmaceutical agents or nutrients), or combinations thereof. Suitable examples of softeners and emulsifiers are described above.
Bulk sweeteners include both caloric and non-caloric compounds. Non-limiting examples of bulk sweeteners include sucrose, dextrose, maltose, dextrin, dried invert sugar, fructose, high fructose corn syrup, levulose, galactose, corn syrup solids, tagatose, polyols (e.g., sorbitol, mannitol, xylitol, lactitol, erythritol, and maltitol), hydrogenated starch hydrolysates, isomalt, trehalose, or mixtures thereof. In some embodiments, the bulk sweetener is present in the chewing gum composition in an amount in the range of about 1 to about 75 weight percent of the chewing gum composition.
Flavoring agents may be used in either the insoluble gum base or soluble portion of the chewing gum composition. Such flavoring agents may be natural or artificial flavors. In some embodiments, the flavoring agent comprises an essential oil, such as an oil produced from a plant or a fruit, peppermint oil, spearmint oil, other mint oils, clove oil, cinnamon oil, oil of wintergreen, bay, thyme, cedar leaf, nutmeg, allspice, sage, mace, and almonds. In another embodiment, the flavoring agent comprises a plant extract or a fruit essence such as apple, banana, watermelon, pear, peach, grape, strawberry, raspberry, cherry, plum, pineapple, apricot, or mixtures thereof. In still another embodiment, the flavoring agent comprises a citrus flavor, such as an extract, essence, or oil of lemon, lime, orange, tangerine, grapefruit, citron, or kumquat.

In some embodiments, the consumable product comprising one or more NHIS, one or more derivatives of NHIS, and/or one or more cooling agents is a cosmetic or skin-care product. As used herein, the term “cosmetic composition” means a composition that is formulated for topical application to skin, which has a pleasant color, odor and feel, and which does not cause unacceptable discomfort (stinging, tautness or redness) liable to discourage the consumer from using it.
Cosmetic composition may be preferably formulated in the form of an emulsion, e.g., W/O (water-in-oil), O/W (oil-in-water), W/O/W (water-in-oil-in-water), O/W/O (oil-in-water-in-oil) emulsion, PIT emulsion, Pickering emulsion, emulsion with a low oil content, micro- or nanoemulsion, a solution, e.g., in oil (fatty oils or fatty acid esters, in particular C6-C32 fatty acid C2-C30 esters) or silicone oil, dispersion, suspension, creme, lotion or milk, depending on the production method and ingredients, a gel (including hydrogel, hydrodispersion gel, oleogel), spray (e.g., pump spray or spray with propellant) or a foam or an impregnating solution for cosmetic wipes, a detergent, e.g., soap, synthetic detergent, liquid washing, shower and bath preparation, bath product (capsule, oil, tablet, salt, bath salt, soap, etc.), effervescent preparation, a skin care product such as e.g., an emulsion (as described above), ointment, paste, gel (as described above), oil, balsam, serum, powder (e.g., face powder, body powder), a mask, a pencil, stick, roll-on, pump, aerosol (foaming, non-foaming or post-foaming), a deodorant and/or antiperspirant, mouthwash and mouth rinse, a foot care product (including keratolytic, deodorant), an insect repellent, a sunscreen, aftersun preparation, a shaving product, aftershave balm, pre- and aftershave lotion, a depilatory agent, a hair care product such as e.g., shampoo (including 2-in-1 shampoo, anti-dandruff shampoo, baby shampoo, shampoo for dry scalps, concentrated shampoo), conditioner, hair tonic, hair water, hair rinse, styling creme, pomade, perm and setting lotion, hair spray, styling aid (e.g., gel or wax), hair smoothing agent (detangling agent, relaxer), hair dye such as e.g., temporary direct-dyeing hair dye, semi-permanent hair dye, permanent hair dye, hair conditioner, hair mousse, eye care product, make-up, make-up remover or baby product.
In some embodiments, the consumable product comprising one or more NHIS, one or more derivatives of NHIS, and/or one or more cooling agents is a smokable composition. The term “smokable composition,” as used herein, includes any material that can be smoked or inhaled, such as tobacco and cannabis, as well as any smokable material that is burned to provide desirable aromas (e.g., charcoal briquettes for grilling foods, incense etc.). The smoking compositions may encompass cigarettes, electronic cigarettes (e-cigarettes), cigars, pipe and cigar tobacco, chew tobacco, vaporizable liquids, and all forms of tobacco such as shredded filler, leaf, stem, stalk, homogenized leaf cured, reconstituted binders, reconstituted tobacco from tobacco dust, fines, or other sources in sheet, pellet or other forms. “Smokable compositions” also include cannabis compositions (e.g., flower materials, leaf materials, extracts, oils, edible candies, vaporizable liquids, cannabis-infused beverages, etc.) and tobacco substitutes formulated from non-tobacco materials.
Components of the compositions of the present application and methods regarding the same as described herein are useful for improved taste and aroma profiles of many consumable products relative to control samples. The phrase “taste profile”, which is interchangeable with “sensory profile” and “sweetness profile”, may be defined as the temporal profile of all basic tastes of a sweetener. The “temporal profile” may be considered to represent the intensity of sweetness perceived over time in tasting of the composition by a human, especially a trained “taster”. Carbohydrate and polyol sweeteners typically exhibit a quick onset followed by a rapid decrease in sweetness, which disappears relatively quickly on swallowing a food or beverage containing the same. In contrast, high intensity natural sweeteners typically have a slower sweet taste onset reaching a maximal response more slowly, followed by a decline in intensity more slowly than with carbohydrate and polyol sweeteners. This decline in sweetness is often referred to as “sweetness linger” and is a major limitation associated with the use of high intensity natural sweeteners.
In the context of taste tasting, the terms “improve”, “improved” and “improvement” are used interchangeably with reference to a perceived advantageous change in a composition or consumable product upon introduction of the compositions of the present application relative to the original taste profile of the composition or consumable product without the added compositions of the present application, such as improved coolness, improved, freshness, less bitterness, better sweetness, better sour taste, better aroma, better mouth feel, better flavor, less aftertaste, etc. The terms “improve” or “improvement” can refer to a slight change, a change, or a significant change of the original taste profile, etc., which makes the composition more palatable to an individual.
In some embodiments, the composition may be evaluated with reference to the degree of their sucrose equivalence. Accordingly, the components in the compositions of the present application may be diluted or modified with respect to its ingredients to conform with a desired sucrose equivalence.
The onset and decay of sweetness when the composition of the present application containing one or more NHIS, one or more derivatives of NHIS, and/or one or more cooling agents is consumed, the composition can be perceived by trained human tasters and measured in seconds from first contact with a taster’s tongue (“onset”) to a cutoff point (typically 180 seconds after onset) to provide a “temporal profile of sweetness”. A plurality of such human tasters is called a “sensory panel.” In addition to sweetness, sensory panels can also judge the temporal profile of the other “basic tastes”: bitterness, saltiness, sourness, piquance (aka spiciness), and umami (aka savoriness or meatiness). The onset and decay of bitterness when a sweetener is consumed, as perceived by trained human tasters and measured in seconds from first perceived taste to the last perceived aftertaste at the cutoff point, is called the “temporal profile of bitterness.” Aromas from aroma producing substances are volatile compounds which are perceived by the aroma receptor sites of the smell organ, i.e., the olfactory tissue of the nasal cavity. They reach the receptors when drawn in through the nose (orthonasal detection) and via the throat after being released by chewing (retronasal detection). The concept of aroma substances, like the concept of taste substances, is to be used loosely, since a compound might contribute to the typical aroma or taste of one food, while in another food it may cause a faulty aroma or taste, or both, resulting in an off-flavor. Thus, sensory profile may include evaluation of aroma as well.
The term “mouth feel” involves the physical and chemical interaction of a consumable in the mouth. More specifically, as used herein, the term “mouth feel” refers to the fullness sensation experienced in the mouth, which relates to the body and texture of the consumable such as its viscosity. Mouth feel is one of the most important organoleptic properties and the major criteria that consumers use to judge the quality and freshness of foods. Subtle changes in a food and beverage product’s formulation can change mouth feel significantly. Simply taking out sugar and adding a high intensity sweetener can cause noticeable alterations in mouth feel, making a formerly good product unacceptable to consumers. Sugar not only sweetens, it also builds body and viscosity in food and beverage products, and leaves a slight coating on the tongue. For example, reducing salt levels in soup changes not only taste, but can alter mouth feel as well. Primarily it is the mouth feel that is always the compliant with non-sugar sweeteners.
The phrase “sweetness detection threshold” refers to the minimum concentration at which panelists consisting of 1-10 persons are able to detect sweetness in a composition, liquid or solid. This is further defined as provided in the Examples herein and are conducted by the methods described in Sensory Testing for Flavorings with Modifying Properties by Christie L. Harman, John B. Hallagan, and the FEMA Science, Committee Sensory Data Task Force, November 2013, Volume 67, No. 11 and Appendix A attached thereto, the teachings of which are incorporated herein by reference.
“Threshold of sweetness” refers to a concentration of a material below which sweetness cannot be detected, but can still impart a flavor to a consumable (including water). When half of a trained panel of testers determines something is “sweet” at a given concentration, then the sample meets the threshold. When less than half of a panel of testers cannot discern sweetness at a given concentration, then concentrations of the substance below the sweetness level are considered a flavoring agent.
Production of the he composition of the present application may involve the use of any of the following methodologies, including reflux at atmospheric pressure, reaction under pressure, oven drying, vacuum oven drying, roller/drum drying, surface scraped heat exchange, and/or extrusion.
The inventors of the present application have also developed a unique process which can preserve useful flavor substances originating from natural high intensity sweetener plants, including stevia, sweet tea, monk fruit, licorice etc. and recovered in in the form of stevia extracts, sweet tea extracts, monk fruit extracts, licorice etc. Such flavor substances can be further amplified in glycosylation and/or Maillard reactions involving the foregoing extracts in combination with various amine donors as described herein.
Additionally, flavor substances in natural high intensity sweetener plants can also include new flavor substances from new natural high intensity sweetener plant varieties produced by hybridizing, grafting and other cultivating methods.
A flavoring agent, other than a flavor derived from a Maillard reaction product as described herein, can be added to the compositions described herein before or after a Maillard reaction has been effected. Suitable flavoring agents include, for example, natural flavors, vitamins, such as vitamin C, artificial flavors, spices, seasonings, and the like. Exemplary flavor agents include synthetic flavor oils and flavoring aromatics and/or oils, uronic acids (e.g., glucuronic acid and galacturonic acid) or oleoresins, essences, and distillates, and a combination comprising at least one of the foregoing.
During the Maillard reaction or following completion of the Maillard reaction, “top note” agents may be added, which are often quite volatile, vaporizing at or below room temperature. “Top notes” are often what give foods their fresh flavors. Suitable top note agents include but are not limited to, for example, furfuryl mercaptan, methional, nonanal, trans,trans-2,4-decadienal, 2,2′-(dithiodimethylene) difuran, 2-methyl-3-furanthiol, 4-methyl-5-thiazoleethanol, pyrazineethanethiol, bis(2-methyl-3-furyl) disulfide, methyl furfuryl disulfide, 2,5-dimethyl-2,5-dihydroxy-1,4-dithiane, 95%, trithioacetone, 2,3-butanedithiol, methyl 2-methyl-3-furyl disulfide, 4-methylnonanoic acid, 4-methyloctanoic acid, or 2-methyl-3-tetrahydrofuranthiol.

Rebaudioside A offers 3 practical positions (see arrows in Formula III below) for (α 1 →4) extensions with glucose using a glucose donor and glucosyltransferases. A fourth position (see broken arrow in Formula III) is theoretically available only as it would create branching and not extension and is sterically hindered. Considering that glucosyltransferases do not act site-specific, all three available binding positions will be glucosylated in a random order. Subsequent glucosylations are also expected to appear in random order whereby the total number of extension positions remains 3, irrespectively of the number of glucose units attached.
Mathematically, glucosylation follows then the exponential function V = nm where V denotes all possible structural variants, m denotes the number of glucose units attached and n denotes the number of possible positions for glucosylation.
The number of all possible structural variants includes molecules which are chemically identical, but the sequence of glucosylation to yield the identical structure is different. The number of variants with different chemical structures (structural isomers) follow the formula I = (n + m - 1)! / ((n - 1)! * m!) where I denotes structural isomers, m denotes the number of glucose units attached and n denotes the number of possible positions for glucosylation.
Exemplifying, the possible sequence of adding 2 or 3 glucose units is shown below on Table 36-1. The 3 sites for the first glucose unit are denoted as a1, b1, c1 (step 1) the variations for the second glucose unit are denoted as a2, b2 and c2 (step 2) or a3, b3, c3 (step3). Variants in step 2 or 3 with identical chemical structure but different sequence are shown in one row.
Table 36-2 summarizes the number of all possible structural variants and structural isomers for various numbers of initially available (α 1→4) positions for glucosylation. Mathematically the difference between possible structure and structural isomers is explained by considering versus neglecting the sequence of glucosylation.
The formula below shows positions available for (α 1-4) glucosidic bonds in Rebaudioside A (marked by arrows)
