Problems solved by technology

The traditional method usually uses strong acid and strong alkali for hydrolysis, which leads to serious nutrient loss, and it is easy to cause protein and polypeptide deterioration and denaturation, and the hydrolyzed products are non-specific, with many side reactions and many industrial wastes, and the side reaction impurities in the product cannot be obtained. Effective removal, if the product is used in the daily cosmetics industry, it will bring great safety hazards, causing consumer allergies or cosmetic contact dermatitis
[0006] At present, the relevant research on enzymatic hydrolysis of marine protein is mainly used in food and health products, and the hydrolytic enzymes used cannot be recycled, and there are few reports on the industrial scale production of marine compound polypeptide moisturizers through enzymatic modification

Abstract

The invention discloses a preparation method of a natural marine compound polypeptide moisturizing agent, which can be used as a functional additive for daily chemicals. An enzyme immobilization method is employed; a marine animal and plant protein powder and water in a weight ratio of 1:5-1:50 are added with a compound enzyme prepared through an immobilized enzyme technology, wherein the mass concentration of compound enzyme in the solution is 0.1-5%, and a reaction is carried out at the temperature of 30-80 DEG C, under pH value of 5-10 for a hydrolysis time of 1-13 h; and then the immobilized enzyme is separated out, and the reaction products are filtered, decolored and desalinized to obtain the marine compound polypeptide moisturizing agent. Compared with a traditional method, the method has the advantages of multitime recycling of the immobilized compound enzyme, mild hydrolysis conditions, high hydrolysis efficiency and no generation of industrial wastes, and is in line with the new trend of requirements of naturalness, environment-friendliness, safety and non-chemical resource on functional additives for daily chemicals.

Description

technical field [0001] The invention relates to the field of comprehensive development and application of marine proteins, in particular to a preparation method of a natural marine composite polypeptide moisturizer, which belongs to the technical field of production of daily chemical additives. Background technique [0002] About 400,000 species of organisms live in the ocean, which accounts for 71% of the earth's area, accounting for 80% of the total number of species on the earth. Marine organisms growing in the special environment of the ocean (high salinity, high pressure, lack of oxygen, lack of sunlight, etc.) produce and accumulate a large number of substances with special chemical structures and special physiological activities and functions during their growth and metabolism. Substances are important resources for the development of new marine moisturizers. The research and development of marine moisturizing agent is of great significance to make full use of abunda...
