Problems solved by technology

When chemical methods such as strong acid and strong alkali are used to hydrolyze collagen, the hydrolysis reaction is difficult to control, and it is difficult to obtain high-content low-molecular-weight collagen peptides
In addition, a large number of chemical substances are used, which affects food safety and causes serious environmental pollution.
It is difficult to obtain low-molecular-weight collagen by the biological hydrolysis method of hydrolyzing collagen with industrial enzymes
Although there are currently reports of low-molecular-weight collagen peptides obtained by enzymatically hydrolyzing collagen with complex enzymes, the low-molecular-weight collagen peptides obtained by enzymatically hydrolyzing collagen with complex enzymes are prone to unfocused molecular weight distribution or low-molecular-weight collagen peptides. The phenomenon that the content is too high, and it is difficult to remove the pigment substances that affect the appearance of collagen products, and the smell of fishy fish is strong

Abstract

The invention relates to a preparation technology for producing collagen and in particular relates to a preparation technology for producing collagen through enzymolysis of fish scales, belonging to the technical field of collagen extraction. The preparation technology comprises the following steps of (1) washing, (2) alkali treatment, (3) decalcification, (4) cooking, (5) cooling, (6) primary enzymolysis, (7) secondary enzymolysis, (8) yeast fermentation of a fish scale collagen solution, (9) activated carbon adsorption reaction, (10) filtration, (11) concentration, (12) sterilization and (13) spray drying. The method provided by the invention not only can achieve the effect of obtaining collagen peptides with high contents and low molecular components from the fish scales but also can achieve the effects of removing pigment substances affecting the appearances of collagen products and reducing the peculiar fishy smell of collagen, thus improving the values of fish collagen products.

Description

technical field [0001] The invention relates to a preparation process for producing collagen, in particular to a preparation process for producing collagen by enzymatic hydrolysis of fish scales, and belongs to the technical field of collagen extraction. Background technique [0002] Collagen is the protein with the most content and widest distribution in the human body. It is the main protein component of connective tissue, accounting for about 25% of the total body protein. It is mainly distributed in animal skin, bone, cartilage, cornea, inner wall of blood vessels and other tissues . Collagen extracted from animal connective tissue is widely used in industries related to human health, such as food, cosmetics and medical treatment, due to its special protein structure and body affinity. At present, the collagen used in industrial production is mainly type I collagen, which is a high-molecular hard protein composed of three 1000 amino acid peptide chains. It is difficult ...
