Embodiment

[0130] Hereinafter, the present invention will be described more concretely by way of examples. However, the present invention is not limited to these Examples. However, in the following examples and the like, % indicating the concentration of a solution or the like is weight % unless the unit is indicated otherwise.

[0131] I. Cystine-Collagen Peptide Complex

Embodiment I-1

[0133] For the cystine-collagen peptide complex, first, L-cystine was dissolved in a potassium carbonate solution having a pH of 10 or higher at 90°C to prepare a 2% cystine solution. This was returned to room temperature (25° C.), and a 50% aqueous solution of collagen peptide was slowly added thereto and stirred. As the collagen peptide solution used, a 50% aqueous solution (pH 4.6) of collagen peptide (manufactured by Nitta Gelatin Inc.) derived from porcine material with an average molecular weight of 3000 was prepared and added to the above-mentioned 2% cystine solution. At room temperature (25° C.), 32 g of a 50% aqueous solution of the collagen peptide (manufactured by Nitta Gelatin Inc.) was slowly mixed with 5 g of a 2% cystine solution and stirred, and when the pH was lowered to 9, cloudiness occurred. Thereafter, the reaction was continued at room temperature for 30 minutes, and after the completion of the reaction, 8 g of 1M phosphate buffer was added to adjust the...

Embodiment I-2

[0137] A part of the precipitate obtained in Example I-1 was put into a Durham tube, and after degassing according to the conventional method of "Pico Tag amino acid analysis method" which is one of the amino acid composition analysis methods, , acid hydrolysis treatment at 150°C for 1 hour. In addition, after derivatization into PTC amino acid (phenylthiocarbamoyl amino acid) using PITC (phenylisothiocyanate), it was separated by a dedicated HPLC reverse-phase chromatographic column for amino acid composition analysis. As a result, the total amount of cystine and cysteine ​​was detected as cysteine ​​(half cystine) (in amino acid analysis, the total content of cystine and cysteine) was 22.5 mol%. Furthermore, 18.2 mol% was detected as glycine, and 5.2 mol% was detected as proline. Take a part of the precipitate obtained from Comparative Example I-1 as a control, put it into a De Hahn test tube, degas, carry out acid hydrolysis at 150°C for 1 hour, and analyze the amino acid ...

Abstract

The present invention provides an excellent cystine-containing complex, which is a functional material that can be added to foods and beverages or cosmetics, and has the effect of cystine and collagen peptide or The role of keratin or amino acids. The present invention also provides food, beverages and cosmetics containing the above-mentioned cystine-containing complex. The cystine-containing complex can be produced through the following steps: a step of dissolving cystine in an alkaline solution with a pH of 10 or more; A process in which a solution or a solution containing amino acids dissolved in an acidic solution is mixed and stirred to form a complex in a solution with a pH of less than 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...
