Description

DESCRIPTION NUTRITIONAL COMPOSITIONS COMPRISING A CASEIN HYDROLYSATE, AS WELL AS DIETARY BUTYRATE AND/OR A COMPOUND FOR STIMULATING FORMATION OF ENDOGENOUS BUTYRATE TECHNICAL FIELD
[00011The present disclosure relates generally to nutritional compositions comprising dietary butyrate and a component, which can stimulate the production of endogenous butyrate. The nutritional compositions are suitable for administration to pediatric subjects. Additionally, the disclosure relates to nutritional compositions including a prebiotic comprising polydextrose and galacto-oligosaccharides, dietary butyrate, and a protein equivalent source. Further, disclosed are methods for reducing the incidence of allergy and/or improving tolerance to cow's milk allergy in target subjects. The disclosed nutritional compositions may provide additive and or/synergistic beneficial health effects. BACKGROUND ART
[0002] Administration of nutritional compositions or other compositions including butyrate or butyrate derivatives often suffer from difficulties regarding the bioavailability of butyrate upon administration. For example, certain butyrate derivatives undergo degradation or oxidation, which ultimate affect the bioavailability of the butyrate derivative upon ingestion. As such, compositions including butyrate derivatives may not provide therapeutic efficacy upon ingestion given the degradation of the butyrate derivative.
[0003] Additionally, nutritional compositions including butyrate may suffer from poor palatability. The unpleasant taste and odor of compositions including butyrate can make the oral administration of certain nutritional compositions including butyrate difficult, especially in the pediatric population. For example, certain butyric acid derivatives at room temperature are present as a dense liquid having an unpleasant taste and intense odor.
[0004] Accordingly, it would be beneficial to provide a nutritional composition that includes endogenous butyrate to avoid the palatability issues sometimes found with dietary butyrate. Further, there is a need for palatable, safe, yet effective, nutritional compositions that include a combination of one or more prebiotics, a protein equivalent source, and butyrate to reduce incidence of allergy and increase tolerance to cow's milk allergy in certain subjects. DISCLOSURE OF THE INVENTION
[0005] Briefly, the present disclosure is directed, in an embodiment, to a nutritional composition that includes dietary butyrate and a component which can stimulate the production of endogenous butyrate in the human gut. In some embodiments, the dietary butyrate may be encapsulated. In some embodiments, the endogenous butyrate may be provided by stimulating short chain fatty acid ("SCFA") production by the gut microbiota and the dietary butyrate may be provided by an enriched lipid fraction derived from milk.
[0006] It is to be understood that both the foregoing general description and the following detailed description present embodiments of the disclosure and are intended to provide an overview or framework for understanding the nature and character of the disclosure as it is claimed. The description serves to explain the principles and operations of the claimed subject matter. Other and further features and advantages of the present disclosure will be readily apparent to those skilled in the art upon a reading of the following disclosure. BEST MODE FOR CARRYING OUT THE INVENTION
[0007] Reference now will be made in detail to the embodiments of the present disclosure, one or more examples of which are set forth hereinbelow. Each example is provided by way of explanation of the nutritional composition of the present disclosure and is not a limitation. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made to the teachings of the present disclosure without departing from the scope of the disclosure. For instance, features illustrated or described as part of one embodiment, can be used with another embodiment to yield a still further embodiment.
[0008] Thus, it is intended that the present disclosure covers such modifications and variations as come within the scope of the appended claims and their equivalents. Other objects, features and aspects of the present disclosure are disclosed in or are apparent from the following detailed description. It is to be understood by one of ordinary skill in the art that the present discussion is a description of exemplary embodiments only and is not intended as limiting the broader aspects of the present disclosure.
[0009] The present disclosure relates generally to nutritional compositions comprising dietary butyrate and a component for stimulating the production of endogenous butyrate. Additionally, the disclosure relates to methods for improving the shelf stability and/or organoleptic properties of nutritional compositions including butyrate.
[0010] "Nutritional composition" means a substance or formulation that satisfies at least a portion of a subject's nutrient requirements. The terms "nutritional(s)", "nutritional formula(s)", "enteral nutritional(s)", and "nutritional supplement(s)" are used as non-limiting examples of nutritional composition(s) throughout the present disclosure. Moreover, "nutritional composition(s)" may refer to liquids, powders, gels, pastes, solids, concentrates, suspensions, or ready-to-use forms of enteral formulas, oral formulas, formulas for infants, formulas for pediatric subjects, formulas for children, growing-up milks and/or formulas for adults.
[0011] "Pediatric subject" means a human less than 13 years of age. In some embodiments, embodiments, a pediatric subject refers to a human subject between 1 and 6 years of age. In still further embodiments, a pediatric subject refers to a human subject between 6 and 12 years of age. The term "pediatric subject" may refer to infants (preterm or fullterm) and/or children, as described below.
[00121 "Infant" means a human subject ranging in age from birth to not more than one year and includes infants from 0 to 12 months corrected age. The phrase "corrected age" means an infant's chronological age minus the amount of time that the infant was born premature. Therefore, the corrected age is the age of the infant if it had been carried to full term. The term infant includes low birth weight infants, very low birth weight infants, and preterm infants. "Preterm" means an infant born before the end of the 3 7t week of gestation. "Full term" means an infant born after the end of the 37 th week of gestation.
[0013] "Child" means a subject ranging in age from 12 months to about 13 years. In some embodiments, a child is a subject between the ages of 1 and 12 years old. In other embodiments, the terms "children" or "child" refer to subjects that are between one and about six years old, or between about seven and about 12 years old. In other embodiments, the terms "children" or "child" refer to any range of ages between 12 months and about 13 years.
[0014] "Infant formula" means a composition that satisfies at least a portion of the nutrient requirements of an infant. In the United States, the content of an infant formula is dictated by the federal regulations set forth at 21 C.F.R. Sections 100, 106, and 107.
[0015] The term "medical food" refers enteral compositions that are formulated or intended for the dietary management of a disease or disorder. A medical food may be a food for oral ingestion or tube feeding (nasogastric tube), may be labeled for the dietary management of a specific medical disorder, disease or condition for which there are distinctive nutritional requirements, and may be intended to be used under medical supervision.
[0016] The term "peptide" as used herein describes linear molecular chains of amino acids, including single chain molecules or their fragments. The peptides described herein include no more than 50 total amino acids. Peptides may further form oligomers or multimers consisting of at least two identical or different molecules. Furthermore, peptidomimetics of such peptides where amino acid(s) and/or peptide bond(s) have been replaced by functional analogs are also encompassed by the term "peptide". Such functional analogues may include, but are not limited to, all known amino acids other than the 20 gene-encoded amino acids such as selenocysteine.
[0017] The term "peptide" may also refer to naturally modified peptides where the modification is effected, for example, by glycosylation, acetylation, phosphorylation and component is distinguished from a protein source also disclosed herein. Further, peptides may, for example, be produced recombinantly, semi-synthetically, synthetically, or obtained from natural sources such as after hydrolysation of proteins, including but not limited to casein, all according to methods known in the art.
[0018] The term "molar mass distribution" when used in reference to a hydrolyzed protein or protein hydrolysate pertains to the molar mass of each peptide present in the protein hydrolysate. For example, a protein hydrolysate having a molar mass distribution of greater than 500 Daltons means that each peptide included in the protein hydrolysate has a molar mass of at least 500 Daltons. Accordingly, in some embodiments, the peptides disclosed in Table 1 and Table 2 are derived from a protein hydrolysate having a molar mass distribution of greater than 500 Daltons. To produce a protein hydrolysate having a molar mass distribution of greater than 500 Daltons, a protein hydrolysate may be subjected to certain filtering procedures or any other procedure known in the art for removing peptides, amino acids, and/or other proteinaceous material having a molar mass of less than 500 Daltons. For the purposes of this disclosure, any method known in the art may be used to produce the protein hydrolysate having a molar mass distribution of greater than 500 Dalton.
[00191 The term "protein equivalent" or "protein equivalent source" includes any protein source, such as soy, egg, whey, or casein, as well as non-protein sources, such as peptides or amino acids. Further, the protein equivalent source can be any used in the art, e.g., nonfat milk, whey protein, casein, soy protein, hydrolyzed protein, peptides, amino acids, and the like. Bovine milk protein sources useful in practicing the present disclosure include, but are not limited to, milk protein powders, milk protein concentrates, milk protein isolates, nonfat milk solids, nonfat milk, nonfat dry milk, whey protein, whey protein isolates, whey protein concentrates, sweet whey, acid whey, casein, acid casein, caseinate (e.g. sodium caseinate, sodium calcium caseinate, calcium caseinate), soy bean proteins, and any combinations thereof. The protein equivalent source can, in some embodiments comprise hydrolyzed protein, including partially hydrolyzed protein and extensively hydrolyzed protein. The protein equivalent source may, in some embodiments, include intact protein. More particularly, the protein source may include a) about 20% to about 80% of the peptide component described herein, and b) about 20% to about 80 %of an intact protein, a hydrolyzed protein, or a combination thereof.
[0020] The term "protein equivalent source" also encompasses free amino acids. In some embodiments, the amino acids may comprise, but are not limited to, histidine, isoleucine, leucine, lysine, methionine, cysteine, phenylalanine, tyrosine, threonine, tryptophan, valine, alanine, arginine, asparagine, aspartic acid, glutamic acid, glutamine, glycine, proline, serine, branched chain amino acids. In certain other embodiments, small amino acid peptides may be included as the protein component of the nutritional composition. Such small amino acid peptides may be naturally occurring or synthesized.
[0021] "Fractionation procedure" includes any process in which a certain quantity of a mixture is divided up into a number of smaller quantities known as fractions. The fractions may be different in composition from both the mixture and other fractions. Examples of fractionation procedures include but are not limited to, melt fractionation, solvent fractionation, supercritical fluid fractionation and/or combinations thereof.
[0022] The term "essential amino acid" as used herein refers to an amino acid that cannot be synthesized de novo by the organism being considered or that is produced in an insufficient amount, and therefore must be supplied by diet. For example, in some embodiments, where the target subject is a human, an essential amino acid is one that cannot be synthesized de novo by a human.
[0023] The term "non-essential amino acid" as used herein refers to an amino acid that can be synthesized by the organism or derived by the organism from essential amino acids. For example, in some embodiments, where the target subject is a human, a non-essential amino acid is one that can be synthesized in the human body or derived in the human body from essential amino acids.
[0024] "Milk fat globule membrane" includes components found in the milk fat globule membrane including but not limited to milk fat globule membrane proteins such as Mucin 1, Butyrophilin, Adipophilin, CD36, CD14, Lactadherin (PAS6/7), Xanthine oxidase and Fatty Acid binding proteins etc.
[0025] The term "growing-up milk" refers to a broad category of nutritional compositions intended to be used as a part of a diverse diet in order to support the normal growth and development of a child between the ages of about 1 and about 6 years of age.
[0026] "Milk" means a component that has been drawn or extracted from the mammary gland of a mammal. In some embodiments, the nutritional composition comprises components of milk that are derived from domesticated ungulates, ruminants or other mammals or any combination thereof.
[0027] "Nutritionally complete" means a composition that may be used as the sole source of nutrition, which would supply essentially all of the required daily amounts of vitamins, minerals, and/or trace elements in combination with proteins, carbohydrates, and lipids. Indeed, "nutritionally complete" describes a nutritional composition that provides adequate amounts of carbohydrates, lipids, essential fatty acids, proteins, essential amino acids, conditionally essential amino acids, vitamins, minerals and energy required to support normal
[0028] A nutritional composition that is "nutritionally complete" for a full term infant will, by definition, provide qualitatively and quantitatively adequate amounts of all carbohydrates, lipids, essential fatty acids, proteins, essential amino acids, conditionally essential amino acids, vitamins, minerals, and energy required for growth of the full term infant.
[0029] A nutritional composition that is "nutritionally complete" for a child will, by definition, provide qualitatively and quantitatively adequate amounts of all carbohydrates, lipids, essential fatty acids, proteins, essential amino acids, conditionally essential amino acids, vitamins, minerals, and energy required for growth of a child.
[0030] "Exogenous butyrate" or "dietary butyrate" each refer to butyrate or butyrate derivatives which are intentionally included in the nutritional composition of the present disclosure itself, rather than generated in the gut.
[0031] "Endogenous butyrate" or "butyrate from endogenous sources" each refer to butyrate present in the gut as a result of ingestion of the disclosed composition that is not added as such, but is present as a result of other components or ingredients of the composition; the presence of such other components or ingredients of the composition stimulates butyrate production in the gut.
[0032] The term "cow's milk allergy" describes a food allergy, i e. an immune adverse reaction to one or more of the proteins contained in cow's milk in a human subject. The principal symptoms are gastrointestinal, dermatological, and respiratory symptoms. These can translate into skin rashes, hives, vomiting, diarrhea, constipation and distress. The clinical spectrum extends to diverse disorders: anaphylactic reactions, atopic dermatitis, wheeze, infantile colic, gastro esophageal reflux disease (GERD), esophagitis, colitis gastroenteritis, headache/migraine and constipation.
[0033] The nutritional composition of the present disclosure may be substantially free of any optional or selected ingredients described herein, provided that the remaining nutritional composition still contains all of the required ingredients or features described herein. In this context, and unless otherwise specified, the term "substantially free" means that the selected composition may contain less than a functional amount of the optional ingredient, typically less than 0.1% by weight, and also, including zero percent by weight of such optional or selected ingredient.
[00341 All percentages, parts and ratios as used herein are by weight of the total composition, unless otherwise specified.
[0035] All references to singular characteristics or limitations of the present disclosure shall include the corresponding plural characteristic or limitation, and vice versa, unless otherwise specified or clearly implied to the contrary by the context in which the reference is made.
[0036] All combinations of method or process steps as used herein can be performed in any order, unless otherwise specified or clearly implied to the contrary by the context in which the referenced combination is made.
[0037] The methods and compositions of the present disclosure, including components thereof, can comprise, consist of, or consist essentially of the essential elements and limitations of the embodiments described herein, as well as any additional or optional ingredients, components or limitations described herein or otherwise useful in nutritional compositions.
[0038] As used herein, the term "about" should be construed to refer to both of the numbers specified as the endpoint(s) of any range. Any reference to a range should be considered as providing support for any subset within that range.
[00391 The present disclosure is directed to nutritional compositions including butyrate and LGG. Non-limiting examples of butyrate for use herein include butyric acid, butyrate salts, and glycerol esters of butyric acid. The nutritional compositions may further include a carbohydrate source, a protein source, and a fat or lipid source. In some embodiments, the nutritional compositions may include a component capable of stimulating endogenous butyrate production; in other embodiments, the nutritional compositions may include both dietary and endogenous butyrate.
[0040] The benefit to providing both exogenous and endogenous butyrate is accelerated tolerance acquisition towards cow's milk. Additionally, the benefit to providing both exogenous and endogenous butyrate together with Lacobaci//us rhamnoses GG ("LGG") is accelerated tolerance acquisition toward cow's milk. Conventional dietary management of cow's milk allergy includes the use of formulations containing protein hydrolysates and amino acids rather than intact proteins, and certain probiotics such as Lactobacillus rhamnoses GG ("LGG"),which contribute to accelerated tolerance acquisition towards cow's milk. The inclusion of a component to stimulate endogenous butyrate production by the gut microbiota may further accelerate tolerance acquisition and/or may be applied as a functional replacement of LGG in a nutritional composition. Further, the inclusion of certain probiotics, such as LGG in combination with butyrate, either endogenous or exogenous butyrate, can contribute to accelerated tolerance acquisition towards cow's milk.
[0041] In an embodiment, the component for stimulating endogenous buyrate is a prebiotic comprising both polydextrose ("PDX") and galacto-oligosaccharides ("GOS"). A prebiotic component including PDX and GOS can enhance endogenous butyrate production by microbiota. Butyrate has epigenetic (histone deacetylase inhibition activity) that results in regulatory responses such as generation of regulatory T-cells. In the context of cow s milk allergy, these regulatory responses may result in accelerated tolerance acquisition to cow's milk protein.
[00421 In addition to PDX and GOS, the nutritional composition may also contain one or more other prebiotics which can exert additional health benefits, which may include, but are not limited to, selective stimulation of the growth and/or activity of one or a limited number of beneficial gut bacteria, stimulation of the growth and/or activity of ingested probiotic microorganisms, selective reduction in gut pathogens, and favorable influence on gut short chain fatty acid profile. Such prebiotics may be naturally-occurring, synthetic, or developed through the genetic manipulation of organisms and/or plants, whether such new source is now known or developed later. Prebiotics useful in the present disclosure may include oligosaccharides, polysaccharides, and other prebiotics that contain fructose, xylose, soya, galactose, glucose and mannose.
[0043] More specifically, prebiotics useful in the present disclosure include PDX and GOS, and can, in some embodiments, also include, polydextrose powder, lactulose, lactosucrose, raffinose, gluco-oligosaccharide, inulin, fructo-oligosaccharide (FOS), isomalto oligosaccharide, soybean oligosaccharides, lactosucrose, xylo-oligosaccharide (XOS), chito oligosaccharide, manno-oligosaccharide, aribino-oligosaccharide, siallyl-oligosaccharide, fuco oligosaccharide, and gentio-oligosaccharides.
[0044] In an embodiment, the total amount of prebiotics present in the nutritional composition may be from about 1.0 g/L to about 10.0 g/L of the composition. More preferably, the total amount of prebiotics present in the nutritional composition may be from about 2.0 g/L and about 8.0 g/L of the composition. In some embodiments, the total amount of prebiotics present in the nutritional composition may be from about 0.01 g/100 Kcal to about 1.5 g/100 Kcal. In certain embodiments, the total amount of prebiotics present in the nutritional composition maybe from about 0.15 g/100 Kcal to about 1.5 g/100 Kcal. Insome embodiments, the prebiotic component comprises at least 20% w/w PDX and GOS.
[00451 The amount of PDX in the nutritional composition may, in an embodiment, be within the range of from about 0.015 g/100 Kcal to about 1.5 g/100 Kcal. In another embodiment, the amount of polydextrose is within the range of from about 0.2 g/100 Kcal to about 0.6 g/100 Kcal. In some embodiments, PDX may be included in the nutritional composition in an amount sufficient to provide between about 1.0 g/L and 10.0 g/L. In another embodiment, the nutritional composition contains an amount of PDX that is between about 2.0 g/L and 8.0 g/L. And in still other embodiments, the amount of PDX in the nutritional composition may be from about 0.05 g/100 Kcal to about 1.5 g/100 Kcal.
[0046] The prebiotic component also comprises GOS. The amount of GOS in the nutritional
Kcal. In another embodiment, the amount of GOS in the nutritional composition may be from about 0.2 g/100 Kcal to about 0.5 g/100 Kcal.
[0047] In a particular embodiment, GOS and PDX are supplemented into the nutritional composition in a total amount of at least about 0.015 g/100 Kcal or about 0.015 g/100 Kcal to about 1.5 g/100 Kcal. In some embodiments, the nutritional composition may comprise GOS and PDX in a total amount of from about 0.1 to about 1.0 g/100 Kcal.
[0048] In some embodiments, the nutritional composition includes a source of dietary butyrate that is present in an amount of from about 5 g/100 Kcal to about 500 g/100 kcal.

[0051] The dietary butyrate can be supplied by any suitable source known in the art. Non limiting sources of dietary butyrate includes animal source fats and derived products, such as but not limited to milk, milk fat, butter, buttermilk, butter serum, cream; microbial fermentation derived products, such as but not limited to yogurt and fermented buttermilk; and/or apricot oil, barley, oats, brown rice, bran, green beans, legumes, leafy greens, apples, kiwi, oranges. In some embodiments, the dietary butyrate is synthetically produced. In embodiments where the dietary butyrate is synthetically produced, the chemical structure of the dietary butyrate may be modified as necessary. Further, the dietary butyrate produced synthetically can be purified by any means known in the art to produce a purified dietary butyrate additive that can be incorporated into the nutritional compositions disclosed herein. The dietary butyrate may be provided by dairy lipids and/or triglyceride bound forms of butyrate.
[0052] In some embodiments, the dietary butyrate may be provided in an encapsulated form. In certain embodiments, the encapsulation of the dietary butyrate may provide for longer shelf-stability and may provide for improved organoleptic properties of the nutritional composition. For example, in some embodiments, the dietary butyrate may be encapsulated or coated by the use of, or combination of, fat derived materials, such as mono- and di glycerides; sugar and acid esters of glycerides; phospholipids; plant, animal and microbial derived proteins and hydrocolloids, such as starches, maltodextrins, gelatin, pectins, glucans, caseins, soy proteins, and/or whey proteins.
[0053] The dietary butyric acid may also be provided in a coated form. For example, coating certain glycerol esters of butyric acids and/or amide derivatives of butyric acids with fat derived materials, such as mono- and di-glycerides; sugar and acid esters of glycerides; phospholipids; plant, animal and microbial derived proteins and hydrocolloids, such as starches, maltodextrins, gelatin, pectins, glucans, caseins, soy proteins, and/or whey proteins may improve the shelf-stability of the dietary butyrate and may further improve the overall organoleptic properties of the nutritional composition.
[00541 In certain embodiments, the dietary butyrate comprises glycerol esters of butyric acid. Glycerol esters of butyric acid may offer minimal complexity when formulated and processed in the nutritional composition. Additionally, glycerol esters of butyric acid may improve the shelf life of the nutritional composition including dietary butyrate an may further have a low impact on the sensory attributes of the finished product.
[00551In some embodiments, the dietary butyrate may comprise butyrate salts, for example, sodium butyrate, potassium butyrate, calcium butyrate, magnesium butyrate, and combinations thereof. In some embodiments, the use of selected dietary butyrate salts may improve intestinal health when provided to target subjects. In certain embodiments, dietary butyrate comprises a suitable butyrate salt that has been coated with one or more fats or lipids. In certain embodiments wherein the dietary butyrate comprises a fat coated butyrate salt, the nutritional composition may be a dry-powdered composition into which the dietary
[0056] In some embodiments, the dietary butyrate may comprise any of the butyrate compounds disclosed herein that are formulated to be in complex form with chitosan or one or cyclodextrins. For example, cyclodextrins are cyclic oligosaccharides composed of six (a cyclodextrin), seven (P-cyclodextrin), or eight (gamma-cyclodextrin) units of a-1,4 glucopyranose. Cyclodextrins are further characterized by a hydrophilic exterior surface and a hydrophobic core. Without being bound by any particular theory, the aliphatic butyrate chain would form a complex with the cyclodextrin core, thus increasing its molecular weight and, thus, reducing the volatility of the butyrate compound. Accordingly, the bioavailability of dietary butyrate may be improved when the dietary butyrate includes butyrate compounds in complex form with one or more cyclodextrins. Further, cyclodextrins are bulky hydrophobic molecules that are resistant to stomach acid as well as gastrointestinal enzymes, thus administration of the butyrate-cyclodextrin complex as described herein would promote absorption of the dietary butyrate in the small intestines.
[0057 In some embodiments the dietary butyrate is provided from an enriched lipid fraction derived from milk. For example, bovine milk fat has a butyric acid content that may be 20 times higher than the butyric acid content in human milk fat. Furthermore, among the short chain fatty acids ("SCFAs") present in human milk, ie.fatty acids having a carbon chain length from 4 to 12, butyric acid (C4) is one of the most predominant in bovine milk. As such, bovine milk fat and/or enriched fractions of bovine milk fat may be included in a nutritional composition to provide dietary butyrate.
[0058] In embodiments where the dietary butyrate is provided by an enriched lipid fraction derived from milk the enriched lipid fraction derived from milk may be produced by any number of fractionation techniques. These techniques include but are not limited to melting point fractionation, organic solvent fractionation, super critical fluid fractionation, and any variants and combinations thereof.
[0059] Furthermore, mixtures that may be subjected to the fractionation procedures to produce the enriched lipid fraction include, but are not limited to, bovine whole milk, bovine cream, caprine milk, ovine milk, yak milk, and/or mixtures thereof. In a preferred embodiment the milk mixture used to create the enriched lipid fraction is bovine milk.
[0060] In addition to providing dietary butyrate, the enriched lipid fraction may comprise an one of the following ingredients: saturated fatty acids; trans-fatty acids; branched-chain fatty acids ("BCFAs"), including odd-branched chain fatty acids ("OBCFAs"); conjugated linoleic acid ("CLA"); monounsaturated fatty acids; polyunsaturated fatty acids; cholesterol; phospholipids; and milk fat globule membrane, including milk fat globule membrane protein.
[00611 In some embodiments the enriched lipid fraction includes, per 100 Kcal, one or more from about 0.1 g to 8.0 g of saturated fatty acids; from about 0.2 g to 7.0g trans-fatty acids; from about 0.003 g to about 6.1 g branched-chain fatty acids; from about 0.026 g to about 2.5 g conjugated linoleic acid; from about 0.8 g to about 2.5 g monounsaturated fatty acids; from about 2.3 g to about 4.4 g polyunsaturated fatty acids; from about 100 mg to about 400 mg of cholesterol; from about 50 mg to about 400 mg of phospholipids; and/or from about 10 mg to about 500 mg of milk fat globule membrane.

[0064] In certain embodiments, the PDX- and GOS-containing prebiotic and dietary butyrate is incorporated into a nutritional composition that is an infant formula. Currently, many infant formulas are not formulated with dietary butyrate. One reason that infant formulas include little to no dietary butyrate is due to the unpleasant organoleptic properties exhibited by the nutritional composition when butyrate compounds are incorporated into the nutritional composition. For example, many butyrate compounds exhibit an odor that makes consuming the nutritional composition in which they are incorporated an unpleasant experience. Furthermore, the pediatric and infant population will not readily consume nutritional products having an unpleasant odor, taste, and/or mouthfeel. Accordingly, there exists a need for a nutritional composition formulated for administration to a pediatric subject or an infant that provides butyrate in the gut yet does not have diminished organoleptic properties. The incorporation of a prebiotic to stimulate butyrate production by gut microbiota and certain dietary butyrate compounds disclosed herein, i.e. glycerol esters of butyric acid and amide derivatives of amino acids, into pediatric and infant nutritional compositions will provide butyrate while still providing a pleasant sensory experience.

[0070] The peptide component disclosed herein may be formulated with other ingredients in the nutritional composition to provide appropriate nutrient levels for the target subject. In some embodiments, the peptide component is included in a nutritionally complete formula that is suitable to support normal growth.
[0071] The peptide component may be provided as an element of a protein equivalent source. In some embodiments, the peptides identified in Tables 1 and 2, may be provided by a protein equivalent source obtained from cow's milk proteins, including but not limited to bovine casein and bovine whey. In some embodiments, the protein equivalent source comprises hydrolyzed bovine casein or hydrolyzed bovine whey. Accordingly, in some embodiments, the peptides identified in Table 1 and Table 2 may be provided by a casein hydrolysate. Such peptides may be obtained by hydrolysis or may be synthesized in vitro by methods know to the skilled person.
[0072] A non-limiting example of a method of hydrolysis is disclosed herein. In some embodiments, this method may be used to obtain the protein hydrolysate and peptides of the present disclosure. The proteins are hydrolyzed using a proteolytic enzyme, Protease N. Protease N "Amano" is commercially available from Amano Enzyme U.S.A. Co., Ltd., Elgin, Ill. Protease N is a proteolytic enzyme preparation that is derived from the bacterial species Bacillus subtilis. The protease powder is specified as "not less than 150,000 units/g", meaning that one unit of Protease N is the amount of enzyme which produces an amino acid equivalent to 100 micrograms of tyrosine for 60 minutes at a pH of 7.0. To produce the infant formula of the present disclosure, Protease N can be used at levels of about 0.5% to about 1.0% by weight of the total protein being hydrolyzed.
[0073] The protein hydrolysis by Protease N is typically conducted at a temperature of about 500C. to about 60° C. The hydrolysis occurs for a period of time so as to obtain a degree of hydrolysis between about 4% and 10%. In a particular embodiment, hydrolysis occurs for a period of time so as to obtain a degree of hydrolysis between about 6% and 9%. In another embodiment, hydrolysis occurs for a period of time so as to obtain a degree of hydrolysis of about 7.5%. This level of hydrolysis may take between about one half hour to about 3 hours.
[00741 A constant pH should be maintained during hydrolysis. In the method of the present disclosure, the pH is adjusted to and maintained between about 6.5 and 8. In a particular embodiment, the pH is maintained at about 7.0.
[0075] In order to maintain the optimal pH of the solution of whey protein, casein, water and Protease N, a caustic solution of sodium hydroxide and/or potassium hydroxide can be used to adjust the pH during hydrolysis. If sodium hydroxide is used to adjust the pH, the amount of sodium hydroxide added to the solution should be controlled to the level that it comprises less than about 0.3% of the total solid in the finished protein hydrolysate. A 10% potassium hydroxide solution can also be used to adjust the pH of the solution to the desired value, either before the enzyme is added or during the hydrolysis process in order to maintain the optimal pH.
[0076] The amount of caustic solution added to the solution during the protein hydrolysis can be controlled by a pH-stat or by adding the caustic solution continuously and proportionally. The hydrolysate can be manufactured by standard batch processes or by continuous processes.
[0077] To better ensure the consistent quality of the protein partial hydrolysate, the hydrolysate is subjected to enzyme deactivation to end the hydrolysis process. The enzyme deactivation step may consist include at heat treatment at a temperature of about 820 C. for about 10 minutes. Alternatively, the enzyme can be deactivated by heating the solution to a temperature of about 92° C. for about 5 seconds. After enzyme deactivation is complete, the hydrolysate can be stored in a liquid state at a temperature lower than 10 C.

[0142] The disclosed nutritional composition described herein can, in some embodiments, also comprise a source of 3-glucan. Glucans are polysaccharides, specifically polymers of glucose, which are naturally occurring and may be found in cell walls of bacteria, yeast, fungi, and plants. Beta glucans (p-glucans) are themselves a diverse subset of glucose polymers, which are made up of chains of glucose monomers linked together via beta-type glycosidic bonds to form complex carbohydrates.
[01431 -1,3-glucans are carbohydrate polymers purified from, for example, yeast, mushroom, bacteria, algae, or cereals. (Stone BA, Clarke AE. Chemistry and Biology of (1-3) Beta-Glucans. London:Portland Press Ltd; 1993. ) The chemical structure of p-1,3-glucan depends on the source of thep-1,3-glucan. Moreover, various physiochemical parameters, such as solubility, primary structure, molecular weight, and branching, play a role in biological activities of p-1,3-glucans. (Yadomae T., Structure and biological activities of fungalbeta-1,3 glucans. Yakugaku Zasshi. 2000;120:413-431.)
[0144] P-1,3-glucans are naturally occurring polysaccharides, with or without p-1,6-glucose side chains that are found in the cell walls of a variety of plants, yeasts, fungi and bacteria. P 1,3;1,6-glucans are those containing glucose units with (1,3) links having side chains attached at the (1,6) position(s). P-1,3;1,6 glucans are a heterogeneous group of glucose polymers that share structural commonalities, including a backbone of straight chain glucose units linked by a p-1,3 bond withp-1,6-linked glucose branches extending from this backbone. While this is the basic structure for the presently described class of 0-glucans, some variations may exist. For example, certain yeast p-glucans have additional regions of P(1,3) branching extending from the P(1,6) branches, which add further complexity to their respective structures.
[0145] -glucans derived from baker's yeast, Saccharomyces cerevisiae, are made up of chains of D-glucose molecules connected at the 1 and 3 positions, having side chains of glucose attached at the 1 and 6 positions. Yeast-derivedp-glucan is an insoluble, fiber-like, complex sugar having the general structure of a linear chain of glucose units with a P-1,3 backbone interspersed with p-1,6 side chains that are generally 6-8 glucose units in length. More specifically, p-glucan derived from baker's yeast is poly-(1,6)-p-D-glucopyranosyl-(1,3) P-D-glucopyranose.
[01461Furthermore, -glucans are well tolerated and do not produce or cause excess gas, abdominal distension, bloating or diarrhea in pediatric subjects. Addition of P-glucan to a nutritional composition for a pediatric subject, such as an infant formula, a growing-up milk or another children's nutritional product, will improve the subject's immune response by increasing resistance against invading pathogens and therefore maintaining or improving overall health.
[01471 In some embodiments, the P-glucan is P-1,3;1,6-glucan. In some embodiments, the p 1,3;1,6-glucan is derived from baker's yeast. The nutritional composition may comprise whole glucan particle P-glucan, particulate p-glucan, PGG-glucan (poly-1,6-p-D glucopyranosyl-1,3--D-glucopyranose) or any mixture thereof.
[0148 In some embodiments, the amount of p-glucan in the nutritional composition is between about 3 mg and about 17 mg per 100 Kcal. In another embodiment the amount of P-glucan is between about 6 mg and about 17 mg per 100 Kcal.
[0149] The disclosed nutritional composition described herein can, in some embodiments, also comprise a source of probiotic.

[0151] In an embodiment, the probiotic(s) may be viable or non-viable. As used herein, the term "viable", refers to live microorganisms. The term "non-viable" or "non-viable probiotic" means non-living probiotic microorganisms, their cellular components and/or metabolites thereof. Such non-viable probiotics may have been heat-killed or otherwise inactivated, but they retain the ability to favorably influence the health of the host. The probiotics useful in the present disclosure may be naturally-occurring, synthetic or developed through the genetic manipulation of organisms, whether such new source is now known or later developed.

In another embodiment, the children's nutritional composition may supply about 10 - 30% of the maximum dietary recommendation for any given country, or about 10 - 30% of the average dietary recommendation for a group of countries, per serving of B-vitamins. In yet another embodiment, the levels of vitamin D, calcium, magnesium, phosphorus, and potassium in the children's nutritional product may correspond with the average levels found in milk. In other embodiments, other nutrients in the children's nutritional composition may be present at about 20% of the maximum dietary recommendation for any given country, or about 20% of the average dietary recommendation for a group of countries, per serving.
[0163 In some embodiments the nutritional composition is an infant formula. Infant formulas are fortified nutritional compositions for an infant. The content of an infant formula is dictated by federal regulations, which define macronutrient, vitamin, mineral, and other ingredient levels in an effort to simulate the nutritional and other properties of human breast milk. Infant formulas are designed to support overall health and development in a pediatric human subject, such as an infant or a child.
[0164] In some embodiments, the nutritional composition of the present disclosure is a growing-up milk. Growing-up milks are fortified milk-based beverages intended for children over 1 year of age (typically from 1-3 years of age, from 4-6 years of age or from 1-6 years of age). They are not medical foods and are not intended as a meal replacement or a supplement to address a particular nutritional deficiency. Instead, growing-up milks are designed with the intent to serve as a complement to a diverse diet to provide additional macronutrients plus additional functional dietary components, such as non-essential nutrients that have purported health-promoting properties.
[01651 The exact composition of a growing-up milk or other nutritional composition according to the present disclosure can vary from market-to-market, depending on local regulations and dietary intake information of the population of interest. In some embodiments, nutritional compositions according to the disclosure consist of a milk protein source, such as whole or skim milk, plus added sugar and sweeteners to achieve desired sensory properties, and added vitamins and minerals. The fat composition includes an enriched lipid fraction derived from milk. Total protein can be targeted to match that of human milk, cow milk or a lower value. Total carbohydrate is usually targeted to provide as little added sugar, such as sucrose or fructose, as possible to achieve an acceptable taste. Typically, Vitamin A, calcium and Vitamin D are added at levels to match the nutrient contribution of regional cow milk. Otherwise, in some embodiments, vitamins and minerals can be added at levels that provide approximately 20% of the dietary reference intake (DRI) or 20% of the Daily Value (DV) per serving. Moreover, nutrient values can vary between markets depending on the identified nutritional needs of the intended population, raw material contributions and regional regulations.
[0166] The disclosed nutritional composition(s) may be provided in any form known in the art, such as a powder, a gel, a suspension, a paste, a solid, a liquid, a liquid concentrate, a reconstituteable powdered milk substitute or a ready-to-use product. The nutritional composition may, in certain embodiments, comprise a nutritional supplement, children's nutritional product, infant formula, human milk fortifier, growing-up milk or any other nutritional composition designed for an infant or a pediatric subject. Nutritional compositions of the present disclosure include, for example, orally-ingestible, health promoting substances including, for example, foods, beverages, tablets, capsules and powders. Moreover, the nutritional composition of the present disclosure may be standardized to a specific caloric content, it may be provided as a ready-to-use product, or it may be provided in a concentrated form. In some embodiments, the nutritional composition is in powder form with a particle size in the range of 5 pm to 1500 pm, more preferably in the range of 10 pm to 300pm.
[01671The nutritional compositions of the present disclosure may be provided in a suitable container system. For example, non-limiting examples of suitable container systems include plastic containers, metal containers, foil pouches, plastic pouches, multi-layered pouches, and combinations thereof. In certain embodiments, the nutritional composition may be a powdered composition that is contained within a plastic container. In certain other embodiments, the nutritional composition may be contained within a plastic pouch located inside a plastic container.
[0168] The nutritional compositions described herein, in some embodiments, advantageously reduce the incidence of allergic reaction and improve tolerance to cow's milk allergy in a subject. Further, in some embodiments, the nutritional compositions advantageously reduce the inflammatory response caused by allergy in a subject. Accordingly, the disclosure relates to methods of improving tolerance to cow's milk allergy in a subject. Further, the disclosure relates to methods of reducing the incidence of allergic reaction and reducing the inflammatory response caused by allergy in a subject via administration of the nutritional compositions including PDX/GOS and dietary butyrate as disclosed herein.
[01691 In some embodiments, the method comprises the step of subjecting the target subject to cow's milk and then providing the nutritional composition disclosed herein including PDX/GOS and dietary butyrate to the target subject. In certain embodiments, after the target subject has been subjected to cow's milk, the target subject may be provided with a nutritional composition that includes PDX/GOS and dietary butyrate and a protein equivalent source as disclosed herein. In certain embodiments, the target subject, after being exposed to cow's milk or other allergen, may be administered a nutritional composition comprising PDX/GOS and dietary butyrate, and a protein equivalent source. In certain embodiments, the protein equivalent source may be substantially free of whole and/or intact protein. In certain other embodiments, the protein equivalent source may comprise hydrolyzed protein, amino acids, the peptide component disclosed herein, and combinations thereof. In some embodiments, the nutritional composition includes a protein equivalent source includes amino acids and no hydrolyzed or whole/intact protein.
[0170] In some embodiments, the target subject is not subjected to cow's milk or an allergen prior to administration of the nutritional composition. Thus, in some embodiments, the method is directed to reducing allergic response in a target subject via providing the nutritional compositions disclosed herein including dietary butyrate to the target subject, and subsequently exposing the target subject to cow's milk or other allergen.
[0171] The nutritional compositions described herein, in some embodiments, advantageously reduce the inflammatory response in a subject.
