Description

[Technical field]

[0001] The present invention relates to a beverage containing a glycylproline-containing collagen peptide, and more specifically to a beverage in which the odor and bitterness specific to the glycylproline-containing collagen peptide have been reduced. [Background technology]

[0002] Collagen is a type of protein that accounts for approximately 30% of the total protein in the human body and constitutes all tissues in the body, including skin, ligaments, bones, cartilage, blood vessels, and cornea. In particular, collagen is abundant in the dermis layer of the skin and is thought to play a major role in the water retention and elasticity of the skin. Since the amount of collagen in the body decreases with age, collagen has traditionally been used in various foods and beverages to maintain the water retention and elasticity of the skin.

[0003] Collagen and gelatin, a thermally denatured form of collagen, were often extracted from the skin and bones of cattle, pigs, and other animals and produced industrially. In recent years, however, due to the influence of livestock infectious diseases and other factors, fish-derived collagen extracted from fish scales and skin has come to be widely used for safety reasons.

[0004] Collagen peptides are made by breaking down collagen and gelatin into smaller molecules using enzymes, and are known to be effective for beauty and joints. A wide variety of products containing collagen peptides have been sold so far.

[0005] Meanwhile, research into glycylproline, a dipeptide, has been progressing in recent years, and it is known to promote collagen production (Patent Documents 1 and 2). Glycylproline is obtained by hydrolyzing collagen peptide with an enzyme or the like, but collagen peptides containing glycylproline have a peculiar odor (fishy odor of fish or animals derived from the raw materials) and bitterness, which may affect the flavor when added to beverages.

[0006] However, no technology has been developed to reduce the characteristic odor and bitterness of glycylproline-containing collagen peptides in beverages. In order to enable continuous intake of glycylproline-containing collagen peptides, it is desirable to develop a new technology that can reduce the characteristic odor and bitterness of glycylproline-containing collagen peptides.

[0008] An object of the present invention is to provide an easy-to-drink beverage that has reduced odor and bitterness specific to glycylproline-containing collagen peptide. [Means for solving the problem]

[0009] In view of the above circumstances, the present inventors have conducted extensive research and have found that, in a beverage containing component (A) glycylproline-containing collagen peptide, the following components (B) and (C): (B) Bacopa monniera extract (C) N-acetylglucosamine It has been found that the odor and bitterness peculiar to glycylproline-containing collagen peptides can be reduced by adding Effect of the Invention

[0010] The present invention is excellent in reducing the odor and bitterness peculiar to glycylproline-containing collagen peptides. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] The beverage in the present invention refers to soft drinks in the food field, and examples thereof include nutritional drinks, beauty drinks, health drinks, carbonated drinks, and the like.

[0012] The glycylproline in the present invention is a dipeptide in which glycine and proline are bonded via an amide bond, and its molecular formula is C7H12N2O3. The glycylproline-containing collagen peptide can be obtained by hydrolyzing collagen peptide with an enzyme. Although the glycylproline-containing collagen peptide is highly useful, it tends to have an unpleasant flavor or strong bitterness.

[0013] The collagen peptide of the present invention can be obtained by hydrolyzing collagen or denatured collagen such as gelatin with an acid, an alkali, an enzyme, etc. The average molecular weight of the collagen peptide is not particularly limited, but is preferably 5,000 or less, and more preferably 3,000 or less.

[0014] The collagen used as the raw material for the glycylproline-containing collagen peptide is not particularly limited in terms of origin (beef, pork, fish, etc.), and for example, the bones and skin of animals such as cows, pigs, and chickens, and the scales and skin of fish such as tilapia, pangasius, catfish, salmon, and cod can be used.

[0015] The content of the glycylproline-containing collagen peptide (Component (A)) in the present invention is not particularly limited, but is preferably 0.1 to 11% by weight, more preferably 0.5 to 7% by weight. If it is less than 0.1% by weight, the odor and bitterness specific to the glycylproline-containing collagen peptide are weak, and the effect of the present invention may not be fully exhibited, while if it exceeds 11% by weight, the odor and bitterness specific to the glycylproline-containing collagen peptide cannot be sufficiently suppressed, and the flavor of the beverage may be significantly impaired.

[0016] The content of glycylproline contained in the above component (A) is not particularly limited, but is preferably 0.01 to 5% by weight, more preferably 0.1 to 2% by weight, based on the total amount of collagen peptide.

[0017] The component (B) Bacopa monnieri extract in the present invention can be extracted from the whole plant or leaves of Bacopa monnieri, but the extraction site is not limited thereto. Bacopa monnieri belongs to the family Scrophulariaceae and is a herb that grows naturally in the lowland wetlands of India. Bacopa monnieri extract can be obtained by a conventional method using an extraction solvent. The extraction solvent is not particularly limited, but includes water or alcohols, or a mixture of water and alcohols, and among them, ethanol is preferred. These solvents may be used alone or in combination of two or more.

[0018] The extract may be used as it is in the form of an extracted solution, or may be used after processing such as concentration, dilution, filtration, decolorization with activated carbon or the like, deodorization, ethanol precipitation, etc. Furthermore, the extracted solution may be concentrated to dryness, spray-dried, freeze-dried, etc., and used as a dried product. Commercially available products may also be used.

[0019] The content of the component (B) is not particularly limited, but is preferably 0.003 to 0.5% by weight, more preferably 0.005 to 0.5% by weight. If it is less than 0.003% by weight, the effect of reducing the odor specific to the glycylproline-containing collagen peptide may not be sufficient, and if it exceeds 0.5% by weight, the flavor derived from the Bacopa monniera extract may be too strong, making it difficult to drink.

[0020] The component (C) N-acetylglucosamine in the present invention is a monosaccharide in which the hydroxyl group at the 2-position of glucose is replaced with an acetylamino group, and is obtained by hydrolyzing chitin, a natural polysaccharide derived from the shells of crustaceans such as crabs and shrimps, by a known method, for example, with an acid and an enzyme, and its salts may also be used. Commercially available products may also be used.

[0021] The content of the component (C) is not particularly limited, but is preferably 0.5 to 7% by weight, more preferably 1 to 7% by weight. If it is less than 0.5% by weight, the effect of reducing the bitterness specific to the glycylproline-containing collagen peptide may not be sufficiently obtained, and even if it exceeds 7% by weight, the effect of reducing the bitterness specific to the glycylproline-containing collagen peptide remains unchanged.

[0022] The pH of the beverage of the present invention is not particularly limited, but a pH of 3 to 5 is preferred in consideration of the appropriate acidity.

[0023] The beverage of the present invention may contain other auxiliary ingredients as necessary. For example, sweeteners such as sucrose, glucose, fructose, maltose, honey, starch syrup, sorbitol, maltitol, erythritol, and xylitol, high-intensity sweeteners such as stevia, sucralose, acesulfame potassium, aspartame, and neotame, fruit juices such as apple, grape, mandarin orange, strawberry, and pineapple, colorants such as caramel color and cacao color, flavorings, thickeners such as xanthan gum and tamarind gum, citric acid, malic acid, gluconic acid, phosphoric acid, fluoride, and the like. These include acidulants such as dicyanic acid, tartaric acid, and adipic acid; vitamins such as ascorbic acid, pyridoxine, niacin, tocopherol, and riboflavin; minerals such as calcium, magnesium, iron, zinc, and manganese; and biologically active substances such as amino acids, peptides, coenzyme Q10, DHA, EPA, astaxanthin, ceramide, hyaluronic acid, collagen, elastin, chondroitin sulfate, royal jelly, propolis, and herbal extracts.

[0024] The method for producing the beverage of the present invention is not particularly limited, and the beverage can be produced by the same method as that for beverages that are generally distributed. The container into which the beverage is filled is also not particularly limited, and the beverage can be filled into the same container as that for beverages that are generally distributed. EXAMPLES

[0025] The present invention will now be described in more detail with reference to examples. However, the present invention is not limited to these examples. The contents are in percent by weight.
