Embodiment

[0130] I. Cystine-Collagen Peptide Complex

[0131] Example I-1

Embodiment I-1

[0133] Comparative Example I-1

Embodiment I-2

[0137] Calculated from the results obtained in Example I-1 and Comparative Example I-1, the results of the proportion of amino acids other than free amino acids, reacted with cystine and precipitated, and the amino acid composition of pigskin gelatin (refer to Nitta Gelatin Inc. website Gelatin Research Office "General Properties of Gelatin") is shown in Figure I-1 in terms of amino acid content. In FIG. I-1, the content rate of each amino acid when the ratio of Gly (glycine) contained is set to 1 is shown. In the raw collagen peptide, the ratio of Cys (cystine) is 0 (refer to Nitta Gelatin Inc. website Gelatin Laboratory "General Properties of Gelatin"), which is not shown in Figure I-1.

[0138] As can be seen from the results in Figure I-1, in the precipitate obtained from the cystine-collagen peptide reaction experiment, as amino acids other than Cys (cystine), Gly (glycine), Pro (proline), Ala ( Alanine), Hyp (hydroxyproline) ratio is high. When compared with the amino ...

Abstract

The invention provides an excellent cystine-containing complex and a preparation method thereof, and the cystine-containing complex simultaneously has the effects of cystine and the effects of collagen peptide or keratin or amino acids as a functional material which can be added in foods or cosmetics. The invention further provides a drink food and the cosmetic containing the cystine-containing complex. The cystine-containing complex can be prepared through the following process steps: dissolving the cystine in alkaline solution with pH above 10; and mixing the obtained cystine solution with collagen peptide solution, solution of keratin hydrolysis products or the solution containing the amino acids dissolved in acidic solution, stirring, and forming the complex in the solution with the pH below 10.

Description

technical field [0001] The present invention relates to a cystine-containing complex and a method for producing the same. In addition, the present invention relates to food, drink or cosmetics containing the above-mentioned cystine-containing complex. Background technique [0002] Currently, in the field of food and beverages and cosmetics, food and beverages or cosmetics provided with psychological, physical or biochemical functions are attracting attention. These functionalities depend on the actions of ingredients blended in food and beverages or cosmetics, and various functional materials have been researched at present. [0003] For example, cystine is known to have various effects. [0004] Cystine is a sulfur-containing amino acid known as a main component of the protein keratin constituting hair. It is an amino acid having a structure in which cysteine ​​is formed in five stages from methionine, which is an essential amino acid, in a living body, and two molecules...
