Extraction process of fish collagen peptide

Abstract

The invention discloses an extraction process of fish collagen peptide in the technical field of extraction processes of fish collagen peptide. The process comprises the following specific steps: step 1, adding fish scales into a cleaning device, thoroughly cleaning, and drying; step 2, adding the dried fish scales into a crushing and grinding device, and grinding into powder; step 3, adding the fish meal particles and protease into an emulsifying device for reaction; and step 4, filtering the enzymatic hydrolysate by a third-stage filtering membrane to obtain fish collagen. According to the extraction process of fish collagen peptide, when fish scales are cleaned, a lifting top plate is used for continuously jacking a conveying net belt up and down when the fish scales are conveyed, so that the conveying net belt quickly vibrates to drive the to-be-cleaned fish scales at the top of the conveying net belt to be scattered and turned over, and then a water spraying gun is used for flushing the fish scales, so that the fish scales are thoroughly cleaned, the condition that the scales are bonded together or the bottom surface cannot be thoroughly washed during cleaning is avoided, and the scale cleaning effect is improved.

Description

technical field [0001] The invention relates to the technical field of extraction technology of fish collagen peptides, in particular to an extraction technology of fish collagen peptides. Background technique [0002] Collagen, also known as collagen, is a fibrous protein formed by intertwining three peptide chains. It is a glycoprotein that contains a large amount of glycine, proline, hydroxyproline and sugar. It is widely found in animal skin, bones, In tissues such as cartilage and tendon, it is the most abundant type of protein in the body. There are 19 types of collagens that have been discovered, among which type I collagen, type II collagen and type III collagen are the main components of collagen fibers, which mainly exist in the connective tissue of animals, and play the functions of supporting organs and protecting the body. structural proteins. [0003] In the invention case of the extraction process of fish collagen peptide disclosed in the prior art, the Chin...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a kind of extraction process of fish collagen peptide, to solve above-mentioned background technology, propose in the prior art that fish scale is carried out collagen protein extraction, need first fish scale be cleaned, existing fish scale cleaning device When cleaning the fish scales, when the fish scales are continuously rinsed with a high-pressure water gun, it is impossible to completely guarantee that both sides of the fish scales are thoroughly rinsed, and the fish scales will stick together, making it difficult to completely remove the dirt on the fish scales. The rear surface will be sticky with dirt, which will affect the extraction purity of protein peptides in fish scales
