Example Embodiment

[0019] Example 1:

[0020] A method for preparing deep-sea fish skin collagen peptides. The deep-sea fish skin collagen is added to deionized water containing potassium chloride and sodium carboxymethyl cellulose, and then subjected to complex protease enzymolysis. The enzymatic hydrolysate is decolorized, filtered, Freeze-drying can obtain deep-sea fish skin collagen peptides. The preparation method has the advantages of low investment, simple operation, good protein degradation effect, high yield of fish skin gel protein peptides, whiter collagen peptides, and higher sensory acceptance. It is easy to industrially scale production and has good application value and market. potential.

[0021] The specific steps of enzymatic hydrolysis are as follows: add deionized water to deep-sea fish skin collagen at a substrate concentration of 8%, adjust the pH to 8.6, add a complex protease containing collagenase and flavor protease at a 4% enzyme amount, and then Enzymatic hydrolysis at a...

Abstract

The invention discloses a deep-sea fish skin collagen peptide. The preparation method of the deep-sea fish skin collagen peptide comprises the following steps: adding deionized water containing potassium chloride and sodium carboxymethylcellulose into deep-sea fish skin collagens, performing enzymolysis with compound protease, discoloring and filtering enzymatic hydrolysate, and performing freezedrying, thereby obtaining the deep-sea fish skin collagen peptide. The deep-sea fish skin collagen peptide disclosed by the invention has the beneficial effects that the collagen peptide is relativelywhite, high in sensory acceptance and high in biological activity and can be widely applied to the fields of cosmetics, health foods, medical appliances and the like; and the preparation method of the collagen peptide has the advantages of being low in input, simple in operation, excellent in protein degradation effect and high in fish skin collagen peptide yield.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a deep-sea fish skin collagen peptide. Background technique [0002] In recent years, with the improvement of living standards, the diversity and practicability of people's demand for aquatic resources have gradually increased, thus promoting the rapid development of my country's aquatic product processing industry. However, with the rapid development of the aquatic product processing industry, a large amount of fish leftovers, such as fish skin, fish scales, viscera, fish heads, etc., will be produced. Most of the feed is discarded, which not only causes a great waste of resources, but also causes environmental pollution. Therefore, how to efficiently utilize the nutritionally active substances in fish scraps has attracted great attention from scientific researchers at home and abroad. Among them, the main waste fish skin is rich in collagen, and collagen can account for 60-60% of ...
