Method for continuously producing scale collagen peptide chelated calcium salt and scale collagen peptide

Abstract

A method for continuously producing scale collagen peptide chelated calcium salt and scale collagen peptide belongs to the biological technical field. The method comprises the following steps: (1) pretreating scales; (2) extracting scale collagen polypeptide and calcium solution through the enzyme method; (3) purifying the solution; (4) implementing enzymolysis for the solution; (5) preparing scale collagen peptide chelated calcium salt solution through the peptide calcium chelating technology; (6) separating the solution of the step (5) to obtain precipitate and supernate; (7) dissolving the precipitate in water and drying to obtain a scale collagen peptide chelated calcium salt finished product; (8) concentrating the supernate to remove ethanol, and separating and purifying to obtain scale collagen peptide solution; and (9) drying the solution to obtain a scale collagen peptide powder finished product. The scale collagen peptide chelated calcium salt product, produced by the method, has high biological utilization rate and high safety, and replenishes both peptide and calcium; and the produced scale collagen peptide product has low molecular weight and high purity. The method fully uses the aquatic product leftover scales, and turns the wastes into the wealth, so that the resource utilization rate can be improved, and the environmental friendliness cost can be reduced.

Description

technical field

[0001] The invention relates to the field of fish scale deep processing, and belongs to the field of biotechnology, in particular to a method for continuously producing fish scale collagen peptide chelated calcium salt and fish scale collagen peptide. Background technique

[0002] The high-value development technology for the comprehensive utilization of aquatic product waste is an innovative technology for the efficient comprehensive utilization of marine resources encouraged by national policies, and the high-value development technology for the comprehensive utilization of fish scales is a hot research topic for many researchers. Modern scientific research shows that fish scales are mainly composed of collagen and hydroxyapatite, and products made from fish scales can be widely used in food, pharmaceutical and cosmetic industries.
