Problems solved by technology

Cowhide collagen peptides currently on the market, compared with fish skin collagen peptides, most products are yellowish in color and have a light fishy smell of cowhide, which has a certain impact on the taste of food. As an added raw material, it also affects the quality of the end product
Since the yield of collagen peptides produced by terrestrial vertebrates is lower than that of marine animals, and a large amount of unhydrolyzed debris is produced in the process of enzymatic hydrolysis, which increases the burden on filtration, the cost of producing small molecular peptides that are conducive to human absorption is quite high, so that the production of bovine collagen Many parts of the protein peptide have not been improved

Abstract

The invention discloses a method for preparing yak skin micromolecular collagen peptide by continuous rotary evaporation desolvation and double enzymolysis. The method comprises the following steps of: (1) yak skin pretreatment, (2) homogenization, (3) enzymolysis, (4) centrifugal separation, (5) decolorization, deodorization and desalination, and (6) concentration and drying. The method is characterized in that the enzymolysis in the step (3) comprises the steps of primary enzymolysis, superfine treatment and secondary enzymolysis. Through combination of double enzymolysis and continuous rotary evaporation desolvation, the enzymolysis time can be greatly shortened, the process efficiency is improved, and the prepared yak skin collagen peptide is high in purity, colorless, odorless, smallin molecular weight and beneficial to direct absorption by human bodies.

Description

technical field [0001] The invention belongs to the technical field of collagen peptide extraction, and in particular relates to a method for preparing yak skin small-molecule collagen peptide by continuous rotary evaporation, desolvation and double enzymatic hydrolysis. Background technique [0002] Qinghai is the largest yak production base in the country, accounting for more than one-third of the total number of yaks in the country, and it is widely known as the "Yak Capital of the World". The unique plateau environment makes yaks have extremely strong immunity, strong ultraviolet radiation makes yaks a treasure house of sterile resources, and the natural way of stocking makes yaks have unique nutritional value and reliable safety. Therefore, the yak known as the "roof of the world" is an excellent raw material for extracting collagen peptides, which further increases the utilization value of yak hide and reduces the problem of slaughter "waste". [0003] Among the exist...
