Preparation method of selenium-chelated collagen peptide with tuna bone collagen serving as source

Abstract

The invention relates to a preparation method of a selenium-chelated collagen peptide with tuna bone collagen serving as a source. The preparation method includes: crushing tuna bones, subjecting the crushed tuna bones to pretreatment prior to enzymolysis and adding selenium-enriched yeast so as to obtain the selenium-chelated collagen peptide. The preparation method is short in preparation cycle, high in yield and product purity and capable of removing bitter fishy smell, provides technical assistance for development of selenium-supplementing health food and drugs and also provides a new thought for high-value application of the tuna bones, and the selenium-chelated collagen peptide is good in taste and beneficial to absorption of human bodies.

Description

technical field

[0001] The invention belongs to the technical field of deep processing of aquatic products, and in particular relates to a preparation method of selenium-chelated collagen peptide derived from tuna fish bone collagen which improves purity and extraction rate, removes bitter smell, improves taste and facilitates human body absorption. Background technique

[0002] Tuna (Tunas), also known as tuna and tuna, belongs to the scombroid family of Perciformes. As a deep-sea fish, tuna is not only delicious, but also has high nutritional value, rich in protein, unsaturated fatty acids and vitamins.
