Problems solved by technology

Collagen peptides are extracted by acid and alkali methods. The molecular weight distribution of the product is wide and the uniformity is poor. In order to prepare collagen peptides with a small molecular weight, a large amount of acid and alkali must be consumed in the extraction process, and the extracted product components are very complicated. Subsequent purification deal with trouble

Abstract

The invention discloses a method for producing fish collagen peptides from tilapia scale raw materials, which is prepared by the following steps: pretreatment; activation treatment; collagen extraction; collagen peptide extraction. The method of the present invention can completely enzymatically hydrolyze collagen, the molecular weight of the enzymolyzed product is small and concentrated, the amino acid content of the enzymatically hydrolyzed product is low, and the obtained collagen peptide is a white odorless powder with high yield and the ash content is less than 0.6g / 100g, which not only guarantees the The high yield of protein peptide, and the molecular weight of the prepared collagen peptide is small and concentrated, the finished product is delicate, and the water solubility is good, which is conducive to large-scale production.

Description

technical field [0001] The invention relates to the field of preparation of fish collagen peptides, in particular to a method for producing fish collagen peptides from tilapia scale raw materials. Background technique [0002] Collagen (Collagen) is a kind of macromolecular protein, which is the protein with the most content in animals, accounting for about 25-33% of human protein, equivalent to 6% of human body weight, and has the functions of supporting organs and protecting the body. Collagen is a helical fibrous protein twisted by 3 peptide chains, widely distributed in connective tissue, skin, bone, visceral interstitium, muscle cavity, ligament, sclera and other parts. 70% to 80% of the organic matter in the bone is collagen. When the bone is formed, sufficient collagen fibers must first be synthesized to form the framework of the bone. Therefore, some people call collagen the bone in the bone. Collagen is also the main component in the skin, accounting for more than...
