Patent Application
20230363424
The field of the invention relates to compounds that can be used to enhance the sweet taste of sweeteners and methods of using such sweetness-enhancing compounds.
Consumers generally favor foods and beverages that taste sweet. However, it is also widely known that a high content of readily metabolizable carbohydrates causes a pronounced increase in the blood sugar level, leads to the formation of fatty deposits, and can lead to a plethora of health problems such as dental cavities, obesity, insulin resistance, diabetes and related secondary complications.
The oral detection of all sweeteners, including carbohydrates and noncaloric sweeteners, is performed by the heterodimeric type 1 taste receptor 2 (T1R2)/type 1 taste receptor 3 (T1R3) receptor. This receptor contains multiple binding sites, which explains the chemical diversity of sweet-tasting compounds. Sweet taste enhancers are small molecules that can increase sweetness perception by the modulation of T1R2/T1R3 receptor activity. These compounds act as positive allosteric modulators and boost taste sensation, allowing significant reduction in sweetener content while maintaining the same taste.
It is therefore desirable to develop substances which, in low concentrations, can effectively enhance the sweet taste of currently available sweeteners.
The present invention addresses the problems described above by providing novel sweetness-enhancing compounds.

More generally, the elements and features of any disclosed example or embodiment should be understood to be disclosed generally for use with other aspects and other examples and embodiments. A reference to a component or ingredient being operative or configured to perform one or more specified functions, tasks and/or operations or the like, is intended to mean that it can perform such function(s), task(s), and/or operation(s) in at least certain embodiments, and may well be able to perform also one or more other functions, tasks, and/or operations.
The articles “a,” “an,” and “the” are used herein to refer to one or to more than one (i.e., to at least one) of the grammatical object of the article. By way of example, “an element” means one element or more than one element.
The word “comprising” is used in a manner consistent with its open-ended meaning, that is, to mean that a given product or process can optionally also have additional features or elements beyond those expressly described.
The terms “beverage concentrate,” “concentrate,” and “syrup” are used interchangeably throughout this disclosure and refer to an aqueous sweetener composition suitable for use in beverage preparation. Exemplary embodiments are described elsewhere in this disclosure.
As used herein, the term “Brix” means the sugar content of an aqueous solution (w/w). By way of example only, a solution that is 1-degree Brix contains 1 g of sucrose in 100 grams of solution, while a solution that is 5 degrees Brix contains 5 g sucrose in 100 g solution.
As used herein, the phrase “edible consumables” means a food, beverage, or an ingredient of a food or beverage suitable for human or animal consumption.
The term “sweetness recognition threshold concentration,” as generally used herein, is the lowest known concentration of a given sweetener or combination of sweeteners that is perceivable by the human sense of taste, typically around about 1.5% sucrose equivalence.
As used herein, “taste” refers to a combination of sweetness perception, temporal effects of sweetness perception (i.e., on-set and duration), off-tastes (e.g., bitterness and metallic taste), residual perception (aftertaste), and tactile perception (e.g., body and thickness).
As used herein, a “full-calorie” beverage formulation is one fully sweetened with a caloric sweetener.
The term “caloric sweetener” refers generally to sweeteners which provide significant caloric content in typical usage amounts, e.g., more than about 5 calories per 8 oz. serving of a beverage.
As used herein, the term “non-caloric sweetener” refers to all sweeteners other than caloric sweeteners.
As used herein, a “natural high-potency sweetener” means a natural sweetener which is at least twice as sweet as sugar, i.e., a sweetener which on a weight basis requires no more than half the weight of traditional sugar (sucrose) to achieve an equivalent sweetness. For example, a natural high-potency sweetener may require less than one-half the weight of sugar to achieve an equivalent sweetness in a beverage sweetened to a level of 10 degrees Brix with sugar. Natural high-potency sweeteners include both caloric and non-caloric sweeteners.
As used herein, the phrase “weight percent” refers to a weight percent calculated based on the total weight of a given composition or formulation. By way of example only, a sweetener composition comprising 5 g of a sweetness enhancer as described herein and 95 g of a caloric sweetener, would comprise 5 weight percent of the sweetness enhancer and 95 weight percent of the caloric sweetener.
As used in this disclosure, unless otherwise specified, the term “added,” “combined,” and terms of similar character mean that the multiple ingredients or components referred to (e.g., one or more sweeteners, sweetness enhancers, etc.) are combined in any manner and in any order, with or without stirring.

After testing a large number of molecules, it has been surprisingly discovered that compounds of Formula (I) below unexpectedly act as sweetness enhancers. Accordingly, the present disclosure provides methods and compositions for enhancing the sweetness of one or more sweeteners using a compound of Formula (I), or a physiologically acceptable salt, enantiomer, or solvate thereof, as sweetness enhancer:
In Formula (I), each of moieties Ra, Rb, and Rc is independently H, OH, or an alkoxy group comprising 1 to 5 carbon atoms (“a C1-5 alkoxy group”), provided that at least two of Ra, Rb, and Rc are independently OH or a C1-5 alkoxy group. Each of moieties Rd, Re, Rf, and Rg is independently H, OH, or an alkyl group comprising 1 to 5 carbon atoms (a “C1-5 alkyl group”), provided that Rd is OH or a C1-5 alkyl group. In addition, Rf is H when (i) Ra is —OCH3 and Rb is OH or (ii) Ra is OH and Rb is OCH3. The C1-5 alkyl group and the C1-5 alkoxy group independently may be linear or branched, and each may include 1, 2, 3, 4, or 5 carbon atoms. The range 1-5 should be understood to encompass ranges of 1-4, 1-3, and 1-2. In some embodiments, Rb is OH and Ra is either OH or OCH3. In further embodiments, Rd may be either OH or CH3. It is also to be understood that the compounds of Formula (I) include their isomers and mixtures thereof, for instance the isomers of Formula (Ia) and Formula (Ib):
In some embodiments, the compound of Formula (I) can be Compound (1), Compound (2), or Compound (3):
A sweetener composition according to the present disclosure can include at least one of Compound (1), Compound (2), Compound (3), and/or their respective physiologically acceptable salts, enantiomers, or solvates, inclusive of isomers such as: Compound (1A), Compound (1B), Compound (2A), Compound (2B), Compound (3A), and Compound (3B):
Compounds of Formula (I) can enhance the sweetness of caloric and non-caloric sweeteners and allow manufacturers to reduce the amount of sweetener used in a given food or beverage.
In certain embodiments, one or more compounds of Formula (I) may be combined with one or more sweeteners to form a sweetener composition. In certain embodiments, this blend can be a granular or powdered composition suitable for use as a tabletop sweetener or for addition to food or beverage products. Alternatively, the sweetener composition may be an aqueous solution. The aqueous solution may be a liquid tabletop sweetener or a sweetener solution that is then added to other ingredients to form a beverage or beverage syrup (concentrate). In certain embodiments, the aqueous solution may be a syrup. Alternatively, the compound of Formula (I) can be added directly to food or beverage products already containing a sweetener.
In certain embodiments, the sweetener composition may comprise from about 0.0005 weight percent to about 75 weight percent of one or more compounds of Formula (I). In other embodiments, the sweetener composition can comprise from about 0.0005 weight percent to about 65 weight percent; from about 0.0005 weight percent to about 55 weight percent; from about 0.0005 weight percent to about 45 weight percent; from about 0.0005 weight percent to about 35 weight percent; from about 0.0005 weight percent to about 25 weight percent; from about 0.0005 weight percent to about 20 weight percent; from about 0.0005 weight percent to about 25 weight percent; from about 0.0005 weight percent to about 15 weight percent; from about 0.001 to about 10 weight percent; from about 0.001 to about 5 weight percent, from about 0.001 to about 1 weight percent; or from about 0.001 weight percent to about 0.5 weight percent of the one or more compounds of Formula (I).
In embodiments where the sweetener composition is an aqueous solution, such as a beverage suitable for use without further dilution, the weight percentage of the one or more compounds of Formula (I) in the composition may correspond to a concentration of less than about 1000 ppm, such as, for example, from about 5 ppm to about 800 ppm, from about 50 ppm to about 600 ppm, or from about 100 ppm to about 400 ppm.
In certain embodiments, less than about 1000 ppm of one or more compounds of Formula (I) can be used to enhance the sweetness of a caloric and/or non-caloric sweetener. At this concentration, the quantity of sweetener used in a given food or beverage can be reduced by about 5 to about 40%, and in certain embodiments, from about 10 to about 25%, or about 25%, in comparison to the food or beverage not including phloroglucinol. At less than about 1000 ppm, a compound of Formula (I) does not sweeten by itself, but is suitable to increase sweetness perception by, in certain embodiments, from about 0.5 to about 3 degrees Brix. Thus, in certain embodiments, the sweetener composition described herein can increase sweetness by about 0.5 Brix, about 1 Brix, about 1.5 Brix, about 2 Brix, about 2.5 Brix, or about 3 Brix.
In certain embodiments, the sweetener is a caloric sweetener. In certain embodiments, the compound of Formula (I) and the caloric sweetener are present in a weight ratio of from about 1:150 to about 1:50. In certain embodiments, the sweetener is a non-caloric sweetener. In certain embodiments, the sweetener is a natural non-caloric sweetener selected from the group consisting of rebaudioside A, rebaudioside B, rebaudioside C, rebaudioside D, rebaudioside M, mogrosides, trilobatin, and combinations thereof. In certain embodiments, the compound of Formula (I) and non-caloric sweetener are present in a weight ratio of from about 1.2:1 to about 1:1.2. In certain embodiments, the sweetener composition is a tabletop sweetener.
The sweetness enhancers described in this disclosure are suitable for reducing the amounts of caloric and/or non-caloric sweeteners in orally consumable items while maintaining the desired sweet taste. Compositions comprising the compound of Formula (I) and a sweetener may be orally consumable sweetener compositions finding use in, for example, foods, beverages, syrups, oral pharmaceuticals, and other formulations including the sweetener composition. In certain embodiments, the sweetener composition may be in a dry form, e.g., a solid or powder. However, in other embodiments, the sweetener composition may be in a gel or liquid form.

In some embodiments, nutraceuticals can be used as supplements to food and beverages and as pharmaceutical formulations for enteral or parenteral applications which may be solid formulations, such as capsules or tablets, or liquid formulations, such as solutions or suspensions.
A gel can refer to any colloidal systems in which a network of particles spans the volume of a liquid medium. Although gels mainly are composed of liquids, and thus exhibit densities similar to liquids, gels have the structural coherence of solids due to the network of particles that spans the liquid medium. For this reason, gels generally appear to be solid, jelly-like materials. Gels can be used in a number of applications. For example, gels can be used in foods, paints, and adhesives. Gels that can be eaten are referred to as “edible gel compositions.” Edible gel compositions typically are eaten as snacks, as desserts, as a part of staple foods, or along with staple foods. Examples of suitable edible gel compositions can be, for example, gel desserts, puddings, jams, jellies, pastes, trifles, aspics, marshmallows, gummy candies, and the like. In some embodiments, edible gel mixes generally are powdered or granular solids to which a fluid may be added to form an edible gel composition. Examples of suitable fluids can be, for example, water, dairy fluids, dairy analogue fluids, juices, alcohol, alcoholic beverages, and combinations thereof. Examples of suitable dairy fluids can be, for example, milk, cultured milk, cream, fluid whey, and mixtures thereof. Examples of suitable dairy analogue fluids can be, for example, soy milk and non-dairy coffee whitener.
A composition including one of the present sweetness enhancers may include various pharmaceuticals known in the art. In certain embodiments, a pharmaceutical composition of the present disclosure can contain from about 5 ppm to about 200 ppm of the present sweetness enhancer, and one or more pharmaceutically acceptable excipients. In some embodiments, pharmaceutical compositions of the present disclosure can be used to formulate pharmaceutical drugs containing one or more active agents that exert a biological effect. Accordingly, in some embodiments, pharmaceutical compositions of the present disclosure can contain an effective amount of one or more active agents that exert a biological effect. Suitable active agents are well known in the art (e.g., The Physician's Desk Reference). Such compositions can be prepared according to procedures well known in the art, for example, as described in Remington's Pharmaceutical Sciences, Mack Publishing Co., Easton, Pa., USA.
The present sweetness enhancers also may be used with any suitable dental and oral hygiene compositions known in the art. Examples of suitable dental and oral hygiene compositions may be, for example, toothpastes, tooth polishes, dental floss, mouthwashes, mouthrinses, dentrifices, mouth sprays, mouth refreshers, plaque rinses, dental pain relievers, and the like.
In some embodiments, the sweetener composition can include one or more supplemental sweetness enhancers in addition to those of Formula (I).
In certain embodiments, the consumable composition can include a flavor agent. The flavor agent can be chosen from synthetic flavor oils and flavoring aromatics, and/or oils, oleo resins and extracts derived from plants, leaves, flowers, fruits and so forth, and combinations thereof. Representative flavor oils include cinnamon oil, peppermint oil, clove oil, bay oil, eucalyptus oil, thyme oil, cedar leaf oil, oil of nutmeg, oil of sage, and oil of bitter almonds.

Generally, any flavoring or food additive such as those described in Chemicals Used in Food Processing, pub 1274 by the National Academy of Sciences, pages 63-258 may be used as flavor agents in the invention.
Typically, the consumable compositions of the present invention may be prepared utilizing techniques well known to those of ordinary skill in the art. As such, the consumable compositions of the present invention may include various other components which are customarily used in the preparation of such consumable compositions, and which would be known to those of skill in the art.
The present consumable composition can be formulated into various forms including tablets, chews, edible films, gels, solutions, suspensions, emulsions, and so forth. For example, when the consumable composition of the present invention is in the form of a liquid pharmaceutical composition, or even a toothpaste, dental cream or gel, such a form typically includes a liquid carrier material for the bitter tastant and the bitter blocker. The carrier material may comprise water, typically in an amount of from about 10% to about 90% by weight of the consumable composition. Carrier materials include, but are not limited to, polyethylene glycol (PEG), propylene glycol (PG), glycerin or mixtures thereof. In addition, the consumable composition may include humectants, such as, for example, sorbitol, glycerin, and polyalcohols.

For example, the thickening agent or binder may be selected from the group consisting of finely particulate gel silicas and nonionic hydrocolloids, such as carboxymethyl cellulose, sodium hydroxymethyl cellulose, hydroxyethylcellulose, hydroxypropyl guar, hydroxyethyl starch, polyvinyl pyrrolidone, vegetable gums, such as tragacanth, agar, carrageenans, gum arabic, xanthan gum, guar gum, locust bean gum, carboxyvinyl polymers, fumed silica, silica clays and the like, and combinations thereof. For example, a preferred thickening agent for use in toothpastes is carrageenan available under the trade names GELCARIN® and VISCARIN® from FMC Biopolymers, Philadelphia, Pa., U.S.A. Other thickening agents or binders are polyvinyl pyrrolidone available from Noveon, Inc. Cleveland, Ohio, U.S.A. under the trademark CARBOPOL®, fumed silica under the trademark CAB-O-SIL® available from Cabot Corporation, Boston, Mass., U.S.A., and silica clays available from Laporte Industries, Ltd., London, U.K. under the trademark LAPOINTE®. The thickening agent or binder may be used with or without a carrier, such as glycerol, polyethylene glycol (e.g., PEG-400), or combinations thereof; however, when a carrier is used, preferably up to about 5% thickening agent or binder, more preferably from about 0.1% to about 1.0%, is combined with preferably from about 95.0% to about 99.9% carrier, more preferably from about 99.0% to about 99.9%, based on the total weight of the thickening agent/carrier combination. Furthermore, when the thickening agent or binder is a hydrated silica and it is used with a carrier, preferably from about 5% to about 10% thickening agent or binder is combined with preferably from about 90% to about 95% carrier, based on the total weight of the thickening agent/carrier combination.

Colorants may also include natural food colors and dyes suitable for food, drug and cosmetic applications. For example, food grade and/or pharmaceutically acceptable coloring agents, dyes, or colorants, as would be understood to one skilled in the art, include FD&C colorants such as primary FD&C Blue No. 1, FD&C Blue No. 2, FD&C Green No. 3, FD&C Yellow No. 5, FD&C Yellow No. 6, FD&C Red No. 3, FD&C Red No. 33 and FD&C Red No. 40 and lakes FD&C Blue No. 1, FD&C Blue No. 2, FD&C Yellow No. 5, FD&C Yellow No. 6, FD&C Red No. 2, FD&C Red No. 3, FD&C Red No. 33, FD&C Red No. 40 and combinations thereof.
In addition, the consumable composition of the invention may also include a surfactant, such as sodium lauryl sulfate (SLS) (preferably in an amount of from about 1% to about 2% of the total weight of the oral composition), and/or a preservative, such as sodium benzoate (preferably in an amount of about 0.2% of the total weight of the oral composition).
Sweeteners
As set forth in this disclosure, the sweetness enhancer of Formula (I) can be combined with one or more caloric and/or non-caloric sweeteners to form a sweetener composition. Sweeteners and combinations of sweeteners for use in the sweetener composition can be selected for any of their nutritional characteristics, taste profile, mouthfeel, or other organoleptic properties.
The sweeteners included in the formulations of the compositions and products disclosed here are edible consumables. The sweetener can be a caloric or non-caloric, natural or artificial sweetener, or a combination of such sweeteners, so long as the sweetener or combination of sweeteners provides a taste which is perceived as sweet by the sense of taste. The perception of flavoring agents and sweetening agents can depend to some extent on the interrelation of elements. Flavor and sweetness can also be perceived separately, i.e., flavor and sweetness perception can be both dependent upon each other and independent of each other. For example, when a large amount of a flavoring agent is used, a small amount of a sweetening agent can be readily perceptible and vice versa. Thus, the oral and olfactory interaction between a flavoring agent and a sweetening agent can involve the interrelationship of elements.
When used to sweeten, the sweetener or combination of sweeteners in the sweetener composition is present in an amount above the sweeteners' sweetness recognition threshold concentration.

In certain exemplary embodiments the emulsifier is from about 5% to about 30% of the mixture.
Carbon dioxide may be used to provide effervescence to certain exemplary embodiments of the beverages disclosed here. Any of the techniques and carbonating equipment known in the art for carbonating beverages may be employed. Carbon dioxide may enhance beverage taste and appearance and may aid in safeguarding the beverage purity by inhibiting and/or destroying objectionable bacteria. In certain embodiments, for example, the beverage may have a CO2 level up to about 4.0 volumes carbon dioxide. Other embodiments may have, for example, from about 0.5 to about 5.0 volumes of carbon dioxide. As used herein, one volume of carbon dioxide refers to the amount of carbon dioxide absorbed by a given quantity of a given liquid, such as water, at 60° F. (16° C.) and one atmospheric pressure. A volume of gas occupies the same space as does the liquid by which it is dissolved. The carbon dioxide content may be selected by those skilled in the art based on the desired level of effervescence and the impact of the carbon dioxide on the taste or mouthfeel of the beverage.
In certain embodiments, caffeine may be added to any of the disclosed foods, beverages, or syrups described herein. The amount of caffeine added may be determined by the desired properties of a given food, beverage, or syrup, and any applicable regulatory provisions of the country where the food, beverage, or syrup is marketed. In certain embodiments caffeine may be included in an amount sufficient to provide a final beverage product having less than about 0.02 weight percent caffeine. The caffeine must be of purity acceptable for use in foods and beverages. The caffeine may be natural or synthetic in origin.
The food and beverage products disclosed here may contain additional ingredients, including, generally, any of those typically found in food and beverage formulations. Examples of such additional ingredients include, but are not limited to, caramel and other coloring agents or dyes, foaming or antifoaming agents, gums, emulsifiers, tea solids, cloud components, and mineral and non-mineral nutritional supplements. Examples of non-mineral nutritional supplement ingredients are known to those of ordinary skill in the art and include, for example, antioxidants and vitamins, including Vitamins A, D, E (tocopherol), C (ascorbic acid), B (thiamine), B2 (riboflavin), B6, B12, K, niacin, folic acid, biotin, and combinations thereof. The optional non-mineral nutritional supplements are typically present in amounts generally accepted under good manufacturing practices. Exemplary amounts may be between about 1% and about 100% Recommended Daily Value (RDV), where such RDVs are established. In certain exemplary embodiments the non-mineral nutritional supplement ingredient(s) may be present in an amount of from about 5% to about 20% RDV, where established.
Preservatives may be used in at least certain embodiments of the food products and beverages disclosed here. That is, at least certain exemplary embodiments may contain an optional dissolved preservative system. Solutions with a pH below 4 and especially those below 3 typically are “micro-stable,” i.e., they resist growth of microorganisms, and so are suitable for longer term storage prior to consumption without the need for further preservatives. However, an additional preservative system may be used if desired. If a preservative system is used, it may be added to the product at any suitable time during production, e.g., in some cases prior to the addition of the sweetener composition. As used here, the terms “preservation system” or “preservatives” include all suitable preservatives approved for use in food and beverage compositions, including, without limitation, such known chemical preservatives as benzoates, e.g., sodium, calcium, and potassium benzoate, sorbates, e.g., sodium, calcium, and potassium sorbate, citrates, e.g., sodium citrate and potassium citrate, polyphosphates, e.g., sodium hexametaphosphate (SHMP), and mixtures thereof, and antioxidants such as ascorbic acid, EDTA, BHA, BHT, TBHQ, dehydroacetic acid, dimethyldicarbonate, ethoxyquin, heptylparaben, and combinations thereof. Preservatives may be used in amounts not exceeding mandated maximum levels under applicable laws and regulations.
In the case of beverages in particular, the level of preservative used may be adjusted according to the planned final product pH and/or the microbiological spoilage potential of the particular beverage formulation. The maximum level employed typically is about 0.05 weight percent of the beverage. It will be within the ability of those skilled in the art, given the benefit of this disclosure, to select a suitable preservative or combination of preservatives for beverages according to this disclosure.
Other methods of preservation suitable for at least certain exemplary embodiments of the products disclosed here include, e.g., aseptic packaging and/or heat treatment or thermal processing steps, such as hot filling and tunnel pasteurization. Such steps may be used to reduce yeast, mold and microbial growth in the beverage products. For example, U.S. Pat. No. 4,830,862 discloses the use of pasteurization in the production of fruit juice beverages as well as the use of suitable preservatives in carbonated beverages. U.S. Pat. No. 4,925,686 discloses a heat-pasteurized freezable fruit juice composition which contains sodium benzoate and potassium sorbate. Typically, heat treatment includes hot fill methods typically using high temperatures for a short time, e.g., about 190° F. for 10 seconds, tunnel pasteurization methods typically using lower temperatures for a longer time, e.g., about 160° F. for 10-15 minutes, and retort methods typically using, e.g., about 250° F. for 3-5 minutes at elevated pressure, i.e., at pressure above 1 atmosphere.

The inherent sweetness of Compounds (1), (2), and (3) as perceived by human subjects was evaluated using a two-alternative forced choice “sip and spit” method (2AFC). The 2AFC test used for compound evaluation was a double-blinded and randomized test where taste panelists (n=30) evaluated a pair of sweetener solutions at a time—one sample is a 1.5% sucrose control, while the other is an aqueous solution containing a test compound at the indicated concentration. Panelists were instructed not to eat or drink (except water) for at least 1 hour before the test. During the test panelists were instructed to sip each sample, swirl it around their mouth and then expectorate. After tasting each sample in the pair, panelists were instructed to record whether they perceived the sample as comparable in sweetness to the control. Panelists cleansed their palates by rinsing with water, eating a cracker and waiting for an interval of about 5 minutes. All samples were tested at ambient temperatures. The results of the 2AFC analysis are presented in Table 1 below.
The sweetness enhancing effect of Compounds (1), (2), and (3) when used with certain sweeteners (specifically, sucrose or rebaudioside M) was evaluated using a two-alternative forced choice “sip and spit” method (2AFC). The 2AFC test used for compound evaluation was a double-blinded and randomized test where taste panelists (n=30) evaluated a pair of sweetener solutions at a time—one sample contains aqueous sweetener solution plus compound (test sample), while the other contains the aqueous sweetener solution without compound (control). Each test sample was compared against a positive control. For example, if the test sample contained 5% sucrose solution with Compound (1), the positive control contained a 5% sucrose solution (i.e., without Compound (1)).
Panelists were instructed not to eat or drink (except water) for at least 1 hour before the test. During the test panelists were instructed to sip each sample, swirl it around their mouth and then expectorate. After tasting each sample in the pair, panelists were instructed to record the sample that is “sweeter” in taste. Panelists cleansed their palates by rinsing with water, eating a cracker and waiting for an interval of about 5 minutes. All samples were tested at ambient temperatures. The results of the 2AFC analysis are presented in Table 2 below.
