Patent Application
20210401737
This invention relates to edible compositions, e.g., cookies, comprising prebiotic and probiotic blends for improved gut health.
At the beginning of the last century, the Russian immunologist and Nobel Prize Laurate, Elie Metchnikoff, discovered that the consumption of live bacteria (Lactobacillus bulgaricus) in yogurt or fermented milk had beneficial effects on the gastrointestinal tract of humans (see, e.g., Metchinikoff, E., Prolongation of Life, William Heinermann, London 1910). Defined by the Food and Agriculture Organization (FAO) of the United Nations World Health Organization (WHO) as “live microorganisms which when administered in adequate amounts confer a health benefit to the host,” probiotics are now widely available in the form of foods such as dairy products, juices, capsules, drops, and powders. Health benefits of probiotics include digestive health, normalization of bowel movements, strengthening of the immune system, improved mood, improved heart health, control of cholesterol, neutralization of toxins, countering of allergies and skin problems, as well as the prevention of yeast and fungal infections. Prebiotic formulations that promote the proliferation of probiotic microorganisms in the intestinal tract that confer the aforementioned health benefits are being actively sought. For example, the National Institutes of Health (NIH) is funding new research into how prebiotics could be used to help manage chronic gastro-intestinal disorders such as inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS). Thus, there is an on-going need for improved prebiotic and probiotic compositions.
The present invention discloses a cookie product that addresses the need for improved prebiotic and probiotic formulations that promote gut health.

U.S. Pat. No. 7,101,565 B2 discloses a prebiotic composition comprising a probiotic and prebiotic, and method of delivering a probiotic, prebiotic or composition directly into the intestinal tract of a mammal are disclosed. The probiotic is any beneficial bacteria and the prebiotic is a substance beneficial to a probiotic. Most preferably, the prebiotic includes a mucopolysaccharide. The method preferably involves delivering the prebiotic, probiotic or composition via a delivery tube, such as an enteral feeding tube, directly to a position downstream of the stomach, most preferably to the jejunum.
None of the art described above teaches a cookie product for the oral consumption and delivery of an optimized prebiotic formulation or prebiotic and prebiotic formulation to the gastrointestinal tract.
The present invention and its embodiments relate to edible compositions, such as cookies, comprising prebiotic and probiotic blends for improved gut health.
A first embodiment of the present invention describes a cookie for improving gut health. The cookie fails to contain refined sugars, synthetic vitamins, genetically modified organisms (GMOs), artificial sweeteners, and artificial preservatives. The cookie includes a baked food composition. The baked food composition contains a polyphenol, a resistant starch, and a prebiotic soluble fiber. In other examples, the prebiotic soluble fiber may be lupin flour. In some examples, the prebiotic soluble fiber may be an isomalto-oligosaccharide (IMO), among other components not explicitly listed herein. The resistant starch may be a resistant dextrin, such as Fibersmart™, and/or tigernut flour, among other components not explicitly listed herein. The polyphenol may be a kiwi fruit powder, among other components not explicitly listed herein. In some examples, the baked food composition is a biscuit.
Moreover, in some examples, the prebiotic soluble fiber is present in a range of approximately 15% to approximately 25% (w/w) of the baked food composition and the polyphenol is present in a range of approximately 0.1% to approximately 5% (w/w) of the baked food composition. The resistant starch is present in a range of approximately 15% to approximately 25% (w/w) of the cookie.
The cookie may also include a crème filling sandwiched between two of the biscuits. The crème filing contains a resistant starch, a nut butter, a vegetable fat, and spores of a probiotic bacterium. In some examples, the spores of the probiotic bacterium comprise spores of Bacillus coagulans. The crème filing fails to contain refined sugars, synthetic vitamins, genetically modified organisms (GMOs), artificial sweeteners, and artificial preservatives.
It should be appreciated that consumption of the cookie provides a prebiotic effect and/or a probiotic effect to a consumer. In examples, consumption of the cookie increases Lactobacillus bulgaricus, Bacillus coagulans, Collinsella aerofaciens, Hippurate, Erysipelotrichia, and/or Streptophyta in the consumer. In some examples, consumption of the cookie increases Lactobacillus bulgaricus and butyrate in the consumer.
A second embodiment of the present invention describes a method for making a cookie that provides a prebiotic effect and/or a probiotic effect to the consumer. The method includes: blending dry ingredients comprising a polyphenol, a resistant starch, and a prebiotic soluble fiber with vegetable fat; mixing in water until glomeration and formation of a dough; and baking the dough to produce a baked food composition. The prebiotic soluble fiber may be lupin flour and/or isomalto-oligosaccharide (IMO), among other examples not explicitly listed herein. The resistant starch may be a resistant dextrin, such as Fibersmart™, and/or tigernut flour. The polyphenol may be the kiwi fruit powder.
In some examples, the baked food composition is a biscuit. The method may further comprise: sandwiching a crème filling between two of the biscuits to produce a cookie. The crème filing may be produced by: mixing vegetable fats to form a first mixture; mixing nut butter with a resistant starch to form a second mixture; and blending the first and second mixtures with a natural flavor and probiotic spores until glomeration of the crème filling. The probiotic spores may comprise spores of Bacillus coagulans.
A third embodiment of the present invention describes a cookie that provides a prebiotic effect and/or a probiotic effect to the consumer. The cookie fails to contain refined sugars, synthetic vitamins, genetically modified organisms (GMOs), artificial sweeteners, and artificial preservatives. The cookie comprises at least two baked food compositions formed into a biscuit and a crème filing sandwiched between the at least two baked food compositions. Each of the at least two baked food compositions contains a polyphenol comprising the kiwi fruit powder, a resistant starch comprising a resistant dextrin (e.g., Fibersmart™) and/or tigernut flour, and a prebiotic soluble fiber comprising lupin flour and/or an isomalto-oligosaccharide (IMO), among other examples not explicitly listed herein. The crème filing comprises a resistant starch, a nut butter, a vegetable fat, and spores of a probiotic bacterium. The spores of the probiotic bacterium comprise spores of Bacillus coagulans. Consumption of the cookie increases Lactobacillus bulgaricus, Bacillus coagulans, Collinsella aerofaciens, Hippurate, Erysipelotrichia, and/or Streptophyta in the consumer. In some examples, consumption of the cookie increases Lactobacillus bulgaricus and butyrate in the consumer.
In general, the present invention succeeds in conferring the following benefits and objectives.

The preferred embodiments of the present invention will now be described with reference to the drawings. Identical elements in the various figures are identified with the same reference numerals.
Reference will now be made in detail to each embodiment of the present invention. Such embodiments are provided by way of explanation of the present invention, which is not intended to be limited thereto. In fact, those of ordinary skill in the art may appreciate upon reading the present specification and viewing the present drawings that various modifications and variations can be made thereto.
As used herein, the singular forms “a,” “an,” and “the,” are intended to include the plural forms as well, unless the context clearly indicates otherwise.
As used herein in the specification and in the claims, the phrase “at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase “at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.
As used herein, an “embodiment” means that a particular feature, structure or characteristic is included in at least one or more manifestations, examples, or implementations of this invention. Furthermore, the particular features, structures or characteristics may be combined in any suitable manner, as would be apparent to a person skilled in the art. Combinations of features of different embodiments are ail meant to be within the scope of the invention, without the need for explicitly describing every possible permutation by example. Thus, any of the claimed embodiments can be used in any combination.
The phrase “and/or,” as used herein in the specification and in the claims, should be understood to mean “either or both” of the elements so conjoined, e.g., elements that are conjunctively present in some cases and disjunctively present in other cases. Thus, as a non-limiting example, a reference to “A and/or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc.
When the term “about” is used in conjunction with a numerical range, it modifies that range by extending the boundaries above and below those numerical values. In general, the term “about” is used herein to modify a numerical value above and below the stated value by a variance of 20%, 10%, 5%, or 1%. In certain embodiments, the term “about” is used to modify a numerical value above and below the stated value by a variance of 10%. In certain embodiments, the term “about” is used to modify a numerical value above and below the stated value by a variance of 5%. In certain embodiments, the term “about” is used to modify a numerical value above and below the stated value by a variance of 1%.
When a range of values is listed herein, it is intended to encompass each value and sub-range within that range. For example, “1-5 ng” is intended to encompass 1 ng, 2 ng, 3 ng, 4 ng, 5 ng, 1-2 ng, 1-3 ng, 1-4 ng, 1-5 ng, 2-3 ng, 2-4 ng, 2-5 ng, 3-4 ng, 3-5 ng, and 4-5 ng.
As referred to herein, all compositional percentages are by weight of the total composition, unless otherwise specified. As used herein, the word “include,” and its variants, is intended to be non-limiting, such that recitation of items in a list is not to the exclusion of other like items that may also be useful in the compositions and methods of this technology. Similarly, the terms “can” and “may” and their variants are intended to be non-limiting, such that recitation that an embodiment can or may comprise certain elements or features does not exclude other embodiments of the present technology that do not contain those elements or features.
As used herein, unless stated otherwise, the term “subject” and the term “patient” are used interchangeably herein. In certain embodiments, the subject is a human. In certain embodiments, the human is a pediatric human. In certain embodiments, the subject is an adult human. In certain embodiments, a subject is a human suffering from a gastrointestinal disorder, such as irritable bowel syndrome (IBS) or colitis. In other examples, the subject is an animal.
The terms “effective amount” or “therapeutically effective amount” as used herein, refer to a sufficient amount of at least one agent being administered which achieve a desired result, e.g., to relieve to some extent one or more symptoms of a disease or condition being treated. In certain instances, the result is a reduction and/or an alleviation of the signs, symptoms, or causes of a disease, or any other desired alteration of a biological system. In some embodiments, the effective amount is a dose that is generally effective in alleviating, reducing, noticeably reducing, or eliminating, symptoms associated with a gastrointestinal disorder. In certain instances, an “effective amount” for therapeutic uses is the amount of the composition comprising an agent as set forth herein required to provide a clinically significant decrease in the disorder. An appropriate “effective” amount in any individual case is determined using any suitable technique, such as dose escalation studies.
As used herein, the terms “treat,” “treatment” or “treating” refer to therapeutic treatments, wherein the object is to reverse, alleviate, ameliorate, inhibit, slow down or stop the progression or severity of a gastrointestinal disorder. The term “treating” includes reducing or alleviating at least one adverse effect or symptom of the gastrointestinal disorder. Treatment is generally “effective” if one or more symptoms or clinical markers are decreased. Alternatively, treatment is “effective” if the progression of the disorder is reduced or halted. That is, “treatment” includes not just the improvement of symptoms or markers, but also a cessation of, or at least slowing of, progress or worsening of symptoms compared to what would be expected in the absence of treatment. The term “treatment” also includes providing relief from the symptoms or side-effects of a disorder, e.g. a gastrointestinal disorder.
Prebiotic Constituent
As used herein, a “prebiotic” refers to a nutritional supplement for a probiotic organism, e.g. probiotic bacteria. Prebiotics are food ingredients, for example, oligosaccharides, that are non-digestible by a subject (e.g., by a mammal, such as a human), but are able to stimulate the growth or activity of one or more beneficial microorganisms. In certain embodiments, a prebiotic organism can inhibit the growth or the activity of one or more pathogenic bacteria. In certain embodiments, a prebiotic organism can selectively stimulate the growth and/or the activity of one or of a limited number of bacteria in the subject.
For a food ingredient to be classified as a prebiotic, it should neither be hydrolyzed, nor absorbed in the upper gastrointestinal tract. Moreover, for a food ingredient to be classified as a prebiotic, it must be selectively fermented by one or a limited number of potentially beneficial bacteria commensal to the colon, such as lactobacilli and bifidobacteria, which are stimulated to grow and/or become metabolically activated. Additionally, for a food ingredient to be classified as a prebiotic, it must be able to alter the colonic microflora towards a healthier composition, by increasing, for example, numbers of saccharolytic species while reducing the number of harmful bacteria (e.g., clostridia and/or Escherichia coli).
Exemplary prebiotics can be found in plants, like the Jerusalem artichoke, chicory root, apples, bananas, asparagus, onions, leeks, and garlic. Moreover, some yogurts, cereals, and breads contain prebiotic additives, like galacto-oligosaccharides (GOS), fructo-oligosaccharides (FOS), and inulin.
The present disclosure describes a baked food product or composition. The baked food product or composition contains no refined sugars, synthetic vitamins, genetically modified organisms (GMOs), artificial sweeteners, or artificial preservatives. In examples, the baked food product or composition may comprise one or more organic ingredients or components. In some examples, the baked food product is a biscuit. The baked food product may comprise a blend of prebiotic soluble fibers, a polyphenolic compound, and a resistant starch, among other components.
In certain embodiments, the prebiotic soluble fibers may comprise a dry flour blend of two or more different types of prebiotics fibers that are soluble in water. In certain embodiments, the prebiotic soluble fibers comprise a dry flour blend of three different prebiotic soluble fibers that are formulated to promote a probiotic, e.g., a bifidogenic, response. In some examples, the prebiotic soluble fibers comprises approximately 15-25% (w/w) of the baked food composition.
One study evaluated the raffinose family of oligosaccharides (RFOs) isolated from lupin seeds (Lupinus albus var. Multolupa) for bifidogenic effects during the manufacture of probiotic fermented milk. See, Cristina Martinez-Villaluenga, et al., “Raffinose Family of Oligosaccharides From Lupin Seeds as Prebiotics: Application in Dairy Products,” J. Food. Prot., 2005, 68(6), Pages 1246-52. A mixed starter inoculum was composed of Bifidobacterium lactis Bb-12 and Lactobacillus acidophilus (1:1). Lupins are a rich source of RFOs that can be used as functional food ingredients. According to this study, the addition of RFOs to milk increased Bifidobacterium lactis Bb-12 and Lactobacillus acidophilus populations at the final fermentation time compared with controls. Final fermentation products were positively affected by addition of RFOs, and the time of fermentation was reduced from 12 to 10 hours. When RFOs were added to milk, they were preferentially used as a carbon source (57.7%) compared with lactose (23.7%) at the end of fermentation. These results of this study suggest that the eventual choice of Bifidobacterium lactis Bb-12 and Lactobacillus acidophilus in a mixed culture at a 1:1 ratio and addition of RFOs to produce a fermented milk product would have the advantages of rapid growth and acidificationrate and would likely increase the probiotic effect of the final functional product. Based on this study, exemplary blends of prebiotic soluble flours described herein comprise lupin flour.
In certain embodiments, a prebiotic formulation for improved digestive health may comprise an isomalto-oligosaccharide (IMO) as a prebiotic soluble fiber. An example IMO is VitaFiber™, which is a commercially available prebiotic, a non-genetically modified organism (GMO), and a corn-free dietary soluble fiber comprising isomalto-oligosaccharide sourced from the root of the tapioca plant. VitaFiber™ is minimally processed with no preservatives, gluten, or allergens. It should be appreciated that the prebiotic soluble flours are not limited to lupin flour and/or the IMO, and other prebiotic soluble fibers not explicitly listed herein are contemplated.
The baked food product or composition may also comprise a polyphenolic compound. In some examples, the polyphenol comprises approximately 0.1-5% (w/w) of the baked food composition. The polyphenolic compound can be used to modify the taste and/or flavor of edible consumables, that is, finished compound foods and beverages, by incorporating therein an effective amount of a monomeric or oligomeric polyphenol (MPP and OPP).
In certain embodiments, polyphenolic compounds may include proanthocyanidins (PCs) including monomeric proanthocyanidins (MPCs) and oligomeric proanthocyanidins (OPCs), and other phenolic based monomers and oligomers usually improving the flavor, taste, mouthfeel and character, that is, the sensory qualities of various food systems and selected food ingredients. In certain embodiments, the polyphenolic compound comprises whole kiwi fruit powder (such as Livaux™ from Zespri KiwiFruit). Without being held to any particular theory, it is believed the fiber of the Kiwifruit provides the prebiotic benefit, and its polyphenolic compound supports gut transit.
The baked food product or composition may also comprise a resistant starch. In some examples, the resistant starch comprises approximately 15-25% (w/w) of the baked food composition. Enzyme resistant starch is an indigestible form of starch that can behave like a dietary fiber. See, Cihadiye Candal, et al., “The effects of different processes on enzyme resistant starch content and glycemic index value of wheat flour and using this flour in biscuit production,” Journal of Food Science and Technology, 2019, 56, Pages 4110-4120. More specifically, enzyme resistant starch is a fraction of starch not digested in the small intestine of healthy individuals. Microflora may partially ferment certain types of resistant starch in the large bowel. Furthermore, enzyme resistant starch may be defined as the sum of starch and products of starch degradation not absorbed in the small intestine, and it may be classified into four types. See, U.S. Pat. No. 6,613,373 B2, granted on Sep. 2, 2003, the contents of which are incorporated by reference in its entirety.
Type I resistant starch is physically inaccessible starch and is locked in the plant cell. Type I resistant starch is a fraction which can be found in foodstuffs with partially milled grains and seeds and legumes. Native granular starch found in uncooked ready-to-eat starch-containing foods, such as in bananas, is classified as type II resistant starch. Enzyme susceptibility of type II resistant starch is reduced by the high density and the partial crystallinity of the granular starch. The amount of type I and type II resistant starches is generally less than about 12% by weight, based upon the total amount of uncooked or raw starch contained in the starch source. However, the type I and type II resistant starches have low melting points, do not survive a baking process, and do not exhibit good baking functionality. See, U.S. Pat. No. 6,613,373 B2.
Starch may be treated to obtain an indigestible starch fraction. Depending upon the type of treatment, a type III resistant starch or a type IV resistant starch may be produced. An indigestible starch fraction which forms after certain heat-moisture treatments of the starch, which may be present in, for example, cooled, cooked potatoes, and canned peas or beans, is type III enzyme-resistant starch. In type IV resistant starch, the enzyme resistance is introduced by chemically modifying or thermally modifying the starch. The modification may be the formation of glycosidic bonds, other than alpha-(1-4) or alpha-(1-6) bonds, by heat treatment. Formation of these other glycosidic bonds may reduce the availability of starch for amylolitic enzymes. See, U.S. Pat. No. 6,613,373 B2.
Exemplary forms of resistant starch include, but are not limited to, tigernut flour, green banana flour, and tapioca fiber. Tigernut is a small root vegetable that grows in Northern Africa and the Mediterranean. Tigernut flour is naturally gluten-free. Further, tigernuts contain a variety of nutrients and beneficial plant compounds. Tigernuts are high in fiber, iron, potassium, protein, magnesium, zinc, vitamin E, and vitamin C. Tigernuts are also a rich source of antioxidants, which are beneficial compounds that protect one's body against aging and diseases. Tigernuts also contain antinutrients, such as phytates, oxalates, saponins and tannins, which can reduce nutrient absorption in your gut. Germinating or roasting the tubers prior to eating reduces their antinutrient levels, making it easier for your body to absorb and use the many nutrients they contain.
Tigernuts may also promote a healthy digestion in various ways. First, tigernuts are high in insoluble fiber, which passes through ones gut without being digested. Tigernuts are also presumed to contain resistant starch, a type of fiber that can feed the friendly bacteria in one's gut, helping digestion run smoothly. Moreover, tigernuts may contain enzymes, such as catalases, lipases and amylases, which help break down foods in one's gut, relieving gas, indigestion, and diarrhea.
Further, animal studies show that tigernut extract may help reduce blood sugar levels. This may, in large part, be due to the high fiber content of the tubers which may slow down the absorption of sugar in the gut. See, Chukwuma Ekeanyanwu, et al., “The Phytochemical Composition and Some Biochemical Effects of Nigerian Tigernut (Cyperus esculentus L.) Tuber,” Pakistan Joural of Nutrition, 2010, 9(7), Pages 709-715. Tigernuts are also rich in the amino acid arginine, which may increase insulin production and sensitivity, both of which are important for blood sugar control. See, Diego Soares Carvalho, et al., “L-Arginine Supplementation Improves Insulin Sensitivity and Beta Cell Function in the Offspring of Diabetic Rats Through AKT and PDX-1 Activation,” Eur. J. Pharmacol., 2016, 791, Pages 780-787; and Makoto Umeda, et al., “Arginine-induced insulin secretion in endoplasmic reticulum,” Biochemical and Biophysical Research Communications, 2015, 466(4), Pages 717-722. Moreover, test-tube studies show that tigernut extract may inhibit the action of carb-digesting enzymes in one's gut. As a result, less sugar may be absorbed from ones gut in a way similar to the action of some blood-sugar-lowering diabetic medications. This is thought to potentially lower blood sugar levels, though more research in humans is needed. See, Saheed Sabiu, et al., “Kinetics of Modulatory Role of Cyperus Esculentus L. on the Specific Activity of Key Carbohydrate Metabolizing Enzymes,” Afr. J. Tradit. Complement. Altern. Med., 2017, 14(4), Pages 46-53.
In certain embodiments, the baked food product may contain a processed starch, such as Fibrosmart™. As used herein, the term “processed starch” refers to starch treated physically (e.g. by heat), chemically, and/or enzymatically. In certain embodiments, a processed starch can be a “starch derivative” that includes, but is not limited to, (1) starch or starch components that have been isolated from their grain to remove protein and bran and then partly digested with enzymes or partly hydrolyzed by heat and/or acids, e.g. maltodextrins; or (2) starch or starch components that are chemically modified, e.g. etherified or esterified starch, for better emulsification, solubility or digestibility.
Probiotic Constituent
As used herein, the term “probiotic” refers to live microorganisms, such as certain bacteria and yeast, that when ingested by a host, can be beneficial to the health of the host.
As used herein, the term “probiotic spores” refers to highly resistant spores of probiotic bacteria, e.g. gram-positive bacteria, that are dormant structures with no metabolic activity. Bacterial spores form in response to extreme conditions, such as heat, pressure, extreme acid, or alkaline conditions, any of which kill vegetative, live microorganisms or microflora. In certain embodiments, the probiotic spores comprise spores of Bacillus coagulans, a lactic acid-producing catalase positive, motile, and Gram-positive facultative anaerobe bacterial species within the genus Bacillus.
Exemplary bacterial probiotic species include, but are not limited to, Bacillus coagulans, e.g., Bacillus coagulans hammer, preferably Bacillus coagulans hammer strain Accession No. ATCC 31284, or one or more strains derived from Bacillus coagulans hammer strain Accession No. ATCC 31284 (e.g., ATCC Numbers: GBI-20, ATCC Designation Number PTA-6085; GBI-30 or BC30, ATCC Designation Number PTA-6086; and GBI-40, ATCC Designation Number PTA-6087). See, U.S. Pat. No. 6,849,256 B1, granted on Feb. 1, 2005, the content of which is hereby incorporated by reference in its entirety.
In certain embodiments, the probiotic spores comprise GanedenBC30™ (B. coagulans GBI-30, 6086). See, U.S. Pat. No. 9,446,111 B2, granted on Sep. 20, 2016, U.S. Pat. No. 6,461,607 B 1, granted on Oct. 8, 2002, and U.S. Pat. No. 9,597,286 B2, granted on Mar. 21, 2017, the contents of which are hereby incorporated by reference in their entirety. GanedenBC30™ is a probiotic formulation that has received United States FDA Generally Regarded as Safe (or GRAS) status for doses up to 93.6 billion CFU per day. For a probiotic to be effective, it must survive the transit through the stomach and reach the intestines alive, where it confers a benefit. Unlike other live probiotic compositions, GanedenBC30™ has been shown to survive the acidic pH encountered during passage through the stomach and, after germination, the spores are able to populate the intestines. See, Harue Honda, et al., “Impact of GanedenBC30 (Bacillus coagulans GBI-30, 6086) on population dynamics of the human gut microbiota in a continuous culture fermentation system,” International Journal of Probiotics and Prebiotics, 2011, 6(1), Pages 65-72.
When consumed daily, GanedenBC30™ has been shown in multiple studies to have a supportive effect on the digestive system. See, Kathleen F. Benson, et al., “Probiotic metabolites from Bacillus coagulans GanedenBC30™ support maturation of antigen-presenting cells in vitro,” World J. Gastroenterol., 2012, 18(16), Pages 1875-1883; Gitte S. Jensen, “GanedenBC30™ cell wall and metabolites: anti-inflammatory and immune modulating effects in vitro,” BMC Immunol., 2010, 11(15), Pages 1-14; and J. R. Endres, et al., “One-year chronic oral toxicity with combined reproduction toxicity study of a novel probiotic, Bacillus coagulans, as a food ingredient,” Food and Chemical Toxicology, 2011, 49(5), Pages 1174-1182.
In other examples, the baked food product is a cookie formed from affixing a crème filling between two biscuits. In some examples, such as Example 2 disclosed herein, the crème filing comprises resistant starch, nut butter, vegetable fat, and spores of a probiotic bacterium. Moreover, several examples provided herein comprise peanuts, almonds, and/or nut butter, which have been shown to have prebiotic benefits. See, Rosa M.

Methodologies
Ex-Vivo Fermentation Study
The prebiotic effect of the baked food composition or the biscuit on human gut microbiota was investigated ex vivo in a model of the human colon mimicking physiological and microbiological conditions of a large intestine. See, Christopher Le Lay, et al., “On Lactococcus lactis UL719 Competitivity and Nisin (Nisaplin(®)) Capacity to Inhibit Clostridium Difficile in a Model of Human Colon,” Front Microbiol., 2015, 6, Page 1020. Feces from two healthy adult volunteers were freshly collected and within 1 hour, used to inoculate gellan (2.5%, w/v) and xanthan (0.25%, w/v) beads under anaerobic conditions. See, Gwenaeelle Le Blay, et al., “Stability and Inhibitory Activity of Pediocin PA-1 Against Listeria sp. in Simulated Physiological Conditions of the Human Terminal Ileum.,” Probiotics and Antimicrobial Proteins, 2012, 4, Pages 250-258.
Gel beads (30%) were then transferred into a stirred glass reactor containing fresh Macfarlane culture medium. Fermentation simulating physiological and microbiological conditions of human intestine are described in Christopher Le Lay, et al., “On Lactococcus lactis UL719 Competitivity and Nisin (Nisaplin(®)) Capacity to Inhibit Clostridium Difficile in a Model of Human Colon,” Front Microbiol., 2015, 6, Page 1020 and Gwenaeelle Le Blay, et al., “Stability and Inhibitory Activity of Pediocin PA-1 Against Listeria sp. in Simulated Physiological Conditions of the Human Terminal Ileum.,” Probiotics and Antimicrobial Proteins, 2012, 4, Pages 250-258, the contents of which are hereby incorporated by reference in their entireties.
Solubilized active ingredients may be described in Example 4 and may be depicted in
These solubilized active ingredients or components for the baked food composition were added daily to the simulated colon at approximately 3.56 g/0.1 L, calculated for an estimated daily intake of approximately 26.7 grams of active ingredients/day (e.g., an approximately 40 grams of the cookie serving), accounting for the reactor volume of approximately 0.1 L compared to approximately 0.75 L for the proximal colon volume, and a chime medium supply of approximately 0.2 L medium per day, giving a mean retention time of approximately 12.5 hours.

It should be appreciated that “16S rNA” refers to a ribosomal RNA that is a component of the prokaryotic ribosome 30S subunit. The “S” in 16S is a sedimentation coefficient, that is, an index reflecting the downward velocity of the macromolecule in the centrifugal field. The higher the value, the greater the molecule. The 16S rRNA gene is the DNA sequence corresponding to rRNA encoding bacteria, which exists in the genome of all bacteria. 16S rRNA is highly conserved and specific, and the gene sequence is long enough. The 16S rRNA gene is approximately 1600 base pairs long and includes nine hypervariable regions of varying conservation (V1-V9). See, Yu S. Bukin, et al., “The effect of 16S rRNA region choice on bacterial community metabarcoding results,” Nature: Scientific Data, 2019, 6; M. Kim, et al., “Evaluation of different partial 16S rRNA gene sequence regions for phylogenetic analysis of microbiomes,” Journal of Microbiological Methods, 2011, 84, Pages 81-87; Y. Wang, et al., “Conservative fragments in bacterial 16S rRNA genes and primer design for 16S ribosomal DNA amplicons in metagenomic studies,” PloS ONE, 2009, 4, Page e7401; and S. G. Tringe, et al., “A renaissance for the pioneering 16S rRNA gene,” Current Opinion in Microbiology, 2008, 11, Pages 442-446. Further, the 16S rRNA is a ribosomal RNA necessary for the synthesis of all prokaryotic proteins. Each bacterium contains 5-10 copies of 16S rRNA, which makes the detection sensitivity highly.
16S ribosomal RNA sequences have been used extensively in the classification and identification of bacteria and archaea. The comparison of almost complete 16S rRNA gene sequences has been widely used to establish taxonomic relationships between prokaryotic strains, with 98.65% similarity currently recognized as the cutoff for delineating species. The comparison of the 16S rRNA gene sequence of an isolate against sequences of type strains of all prokaryotic species provides an accurate and convenient way to routinely classify and identify prokaryotes. See, Mincheol Kim, et al., “Chapter 4-16S rRNA Gene-Based Identification of Bacteria and Archaea using the EzTaxon Server,” Methods in Microbiology, 2014, 41, Pages 61-74.
Additionally, more conservative regions of 16S rNA are useful for determining the higher-ranking taxa, whereas more quickly evolving ones can help identify genus or species. Use of the full V3-V4 regions of 16S rRNA has been shown to contribute to a more in-depth characterization of the microbial composition. See, Rodrigo Garcia-Lopez, et al., “Doing More with Less: A Comparison of 16S Hypervariable Regions in Search of Defining the Shrimp Microbiota,” Microorganisms, 2020, 8(134), Pages 1-28. As such, the bacterial diversity was experimentally determined by sequencing the V3-V4 region of 16S rNA using the MiSeq System.
Metabolomic Analysis
Humans lack the enzymes to degrade the bulk of dietary fibers. Therefore, these nondigestible carbohydrates pass the upper gastrointestinal tract unaffected and are fermented in the cecum and the large intestine by the anaerobic cecal and colonic microbiota. Fermentation results in multiple groups of metabolites, of which short-chain fatty acids (SCFAs) are the major group. See, J. K. Nicholson, et al., “Host-gut microbiota metabolic interactions,” Science, 2012, 336(6086), Pages 1262-1267; and C. C. Roy, et al., “Short-chain fatty acids: ready for prime time?,” Nutr. Clin. Pract., 2006, 21(4), Pages 351-366.
SCFAs are a necessary waste product, required to balance redox equivalent production in the anaerobic environment of the gut. See, Milan J. A. van Hoek, et al., “Redox balance is key to explaining full vs. partial switching to low-yield metabolism,” BMC Syst. Biol., 2012, 6(22). SCFAs are saturated aliphatic organic acids that consist of one to six carbons of which acetate, propionate, and butyrate are the most abundant (≥95%). See, S. I. Cook, et al., “Review article: short chain fatty acids in health and disease,” Aliment Pharmacol. Ther., 1998, 12(6), Pages 499-507. Acetate, propionate, and butyrate are present in an approximate molar ratio of 60:20:20 in the colon and stool. See, E. Hijova, et al., “Short chain fatty acids and colonic health,” Bratisl Lek Listy., 2007, 108(8), Pages 354-358; and J. H. Cummings, et al., “Short Chain Fatty Acids in Human Large Intestine, Portal, Hepatic and Venous Blood,” Gut, 1987, 28(10), Pages 1221-1227. Depending on the diet, the total concentration of SCFAs decreases from 70 to 140 mM in the proximal colon to 20 to 70 mM in the distal colon. See, D. L. Topping, et al., “Short-chain fatty acids and human colonic function: roles of resistant starch and nonstarch polysaccharides,” Physiol. Rev., 2001, 81(3), Pages 1031-1064.
SCFAs have been the subject of much research over the past few decades, as SCFAs play a vital role in maintenance of colonic integrity and metabolism. SCFAs are produced when dietary fiber is fermented by colonic bacteria and are absorbed in the colon, at the same time as sodium and water absorption and bicarbonate secretion. Once absorbed, SCFAs are used preferentially as fuel for colonic epithelial cells and have trophic effects on the epithelium.
Concentrations of short-chain fatty acids were determined using gas chromatography with flame ionization detector (or “GC-FID”) and expressed in mM. GC-FID is a common analytical technique that is widely used in the petrochemical, pharmaceutical and natural gas markets. An FID typically uses a hydrogen/air flame into which the sample is passed to oxidize organic molecules and produce electrically charged particles (ions). The ions are collected and produce an electrical signal, which is then measured. As common with other GC techniques, a carrier gas is required with low water and oxygen impurities, since water and oxygen can interact with the stationary phase and cause significant problems, such as high baseline noise and column bleed in the output gas chromatogram, which both reduces the analyzer sensitivity and decreases column lifetime.
Also, amino acids metabolism and production of neuroactive compounds (e.g., GABA, serotonin, and dopamine) by gut microbiota were quantified using gas chromatography-mass spectrometry (or “GC-MS”). It should be appreciated that GC-MS is an analytical method that combines the features of gas-chromatography and mass spectrometry to identify different substances within a test sample. Applications of GC-MS include drug detection, fire investigation, environmental analysis, explosives investigation, and identification of unknown samples.
Results of Methodologies
“Metagenomics” is the study of genetic material recovered directly from environmental samples. This field may also be referred to as environmental genomics, ecogenomics or community genomics. While traditional microbiology, microbial genome sequencing, and genomics rely upon cultivated clonal cultures, early environmental gene sequencing cloned specific genes (often the 16S rRNA gene) to produce a profile of diversity in a natural sample. Such work revealed that the vast majority of microbial biodiversity had been missed by cultivation-based methods. Because of its ability to reveal the previously hidden diversity of microscopic life, metagenomics offers a way to view the microbial world. See, John C. Wooley, et al., “Metagenomics: Facts and Artifacts, and Computational Challenges,” J. Comput. Sci. Technol., 2009, 25(1), Pages 71-81.
Metagenomic results are depicted, at least, in
Rarefaction is a statistical technique used to approximate the number of operational taxonomic units (OTUs) expected in a random sample of individuals taken from a sample collection. Rarefaction can be used to measure bacterial richness (e.g., relative richness; measurement of OTUs actually observed in samples). See, Bo-Ra Kim, et al., “Deciphering Diversity Indices for a Better Understanding of Microbial Communities,” J. Microbiol. Biotechnol., 2017, 27(12), Pages 2089-2093.
The diversity index is a quantitative measure that reflects how many different types (such as species) there are in a dataset (a community) and that can simultaneously take into account the phylogenetic relations among the individuals distributed among those types, such as richness, divergence or evenness. It should be appreciated that the analysis of microbial community diversity, there is no general agreement on which diversity index is the best to use. See, J. B. Hughes, et al., “Application of ecological diversity statistics in microbial ecology,” Molecular Microbial. Ecology Manual, 2004, Second Edition, 7.01, Pages 1321-1344.
Chaol indices are used to estimate richness. See, Bo-Ra Kim, et al. More specifically, Chaol is a nonparametric method for estimating the number of species in a community. The Chao richness estimator is based on the concept that rare species infer the most information about the number of missing species. See, A. Chao, “Non-parametric estimation of the number of classes in a population,” Journal of Statistics, 1984, 11, Pages 265-270; and A. Chao, “Estimating the Population Size for Capture-Recapture Data with Unequal Catchability,” Biometrics, 1987, 43, Pages 783-791.
Shannon-Weaver and Simpson diversity indices are commonly used in bacterial diversity measurement based on OTUs. The OTUs are inferred to exist based on sequence data, and can be defined at different levels of resolution (e.g., phylum, class, order, family, genus, and species). See, Bo-Ra Kim, et al. Specifically, the Shannon diversity index is another index that is commonly used to characterize species diversity in a community. The Shannon index accounts for both abundance and evenness of the species present.
Linear discriminant analysis (LDA), normal discriminant analysis (NDA), or discriminant function analysis is a generalization of Fisher's linear discriminant, a method used in statistics, pattern recognition, and machine learning to find a linear combination of features that characterizes or separates two or more classes of objects or events.
Linear discriminant analysis effect size or “LEfSe” determines the features (e.g., organisms, clades, operational taxonomic units, genes, or functions) most likely to explain differences between classes by coupling standard tests for statistical significance with additional tests encoding biological consistency and effect relevance. Class comparison methods typically predict biomarkers consisting of features that violate a null hypothesis of no difference between classes.
Further, LEfSe emphasizes statistical significance, biological consistency, and effect relevance, allowing researchers to identify differentially abundant features that are also consistent with biologically meaningful categories. LEfSe first robustly identifies features that are statistically different among biological classes. LEfSe then performs additional tests to assess whether these differences are consistent with respect to expected biological behavior; for example, given some known population structure within a set of input samples, is a feature more abundant in all population subclasses or in just one? As a last step, LEfSe uses LDA to estimate the effect size of each differentially abundant feature and, if desired by the investigator, to perform dimension reduction. See, Nicola Segata, et al., “Metagenomic biomarker discovery and explanation,” Genome Biol., 2011, 12(R60), Pages 1-18. The visualization of the discovered biomarkers on taxonomic trees provides an effective means for summarizing the results in a biologically meaningful way.
A “cladogram” is a diagram that may be used to show relations among organisms. A cladogram uses lines that branch off in different directions ending at a clade, a group of organisms with a last common ancestor. There are many shapes of cladograms, but they all have lines that branch off from other lines. The lines can be traced back to where they branch off. These branching off points represent a hypothetical ancestor (not an actual entity), which can be inferred to exhibit the traits shared among the terminal taxa above it. This hypothetical ancestor might then provide clues about the order of evolution of various features, adaptation, and other evolutionary narratives about ancestors.

Collinsella aerofaciens has been associated with a low risk of colon cancer, and patients with IBD present lower gut levels of this genus than do control individuals. See, Evelyne M. Dewulf, et al., “Insight Into the Prebiotic Concept: Lessons From an Exploratory, Double Blind Intervention Study With Inulin-Type Fructans in Obese Women,” Gut, 2013, 62, Pages 1112-1121. The authors reported an association of increased levels of Collinsella and Hippurate, a gut-derived metabolite commonly associated with a “healthy phenotype.” Hippurate is one of the main discriminant metabolites explaining the difference in urine metabolic profiles between lean and obese or diabetic individuals. A patent application has been filled for the use of Collinsella aerofaciens for reducing bloating. See, WO 2010/125472 A1, published on Nov. 4, 2010. Moreover, increased levels of Collinsella, a genus belonging to Actinobacteria, was significantly augmented with the probiotic powder of
A previous study investigating altered microbiota composition in patients with major depression disorder (MDD) have reported that relative proportion of Erysipelotrichaceae was significantly lower levels in the MDD than in the healthy control group. See, Haiyin Jiang, et al., “Altered fecal microbiota composition in patients with major depressive disorder,” Brain, Behavior, and Immunity, 2015, 48, Pages 186-194. Still, Erysipelotrichaceae is less studied and no clear conclusion has been drawn about a potent role of this family (as opposed to F. prausnitzii). Similarly, the Erysipelotrichaceae family has significantly increased after addition of the probiotic powder of

Butyrate production has been correlated with many health benefits to the gut, as well as the brain. See, Megan W. Bourassa, et al., “Butyrate, Neuroepigenetics and the Gut Microbiome: Can a High Fiber Diet Improve Brain Health?,” Neurosci Lett., 2016, 625, Pages 56-63. The relationship between ones gut microbiota and nervous system is a large part of the gut-brain axis that has attracted increasing interest in recent years. It is estimated that 90% of the cells in the human body are of microbial origin, and the vast majority of these microbiota are comprised of 15,000-36,000 species of commensal and symbiotic bacteria that reside within the lumen of the gut. See, Daniel N. Frank, et al., “Molecular-phylogenetic characterization of microbial community imbalances in human inflammatory bowel diseases,” Proc. Natl. Acad. Sci. U.S.A., 2007, 104(34), Pages 13780-13785; and R. M. Stilling, et al., “Microbial Genes, Brain & Behaviour—Epigenetic Regulation of the Gut-Brain Axis,” Genes Brain Behay., 2014, 13(1), Pages 69-86.
Some studies have examined the effects of probiotics that would increase butyrate-producing bacteria. These studies showed that the probiotics reduced anxiety in rats and lowered psychological stress in human subjects. See, Michael Messaoudi, et al., “Assessment of Psychotropic-Like Properties of a Probiotic Formulation (Lactobacillus helveticus R0052 and Bifidobacterium longum R0175) in Rats and Human Subjects,” Br.
