Cowhide processing method for preparing collagen

Abstract

The invention provides a cowhide processing method for preparing collagen, and belongs to the technical field of biological food. The method is used for performing fine processing on cowhide before collagen preparation, and the cowhide serves as the main raw materials for preparing the collagen. The method comprises the steps that cow dermis tissue is unfrozen, wherein the frozen cow dermis tissue is placed into a beaker and soaked by adding ultrapure water of which the volume is four times of that of the cow dermis tissue until the cow dermis tissue is unfrozen into loosen tissue particles, and the tissue particles are evenly stirred with a glass rod into paste; the cow dermis tissue particles are mashed into even suspension liquid free of obvious cowhide particles through a tissue masher; the pasty tissue particles are transferred to a glass cup of the tissue masher, ten times volume of ultrapure water is added, homogenization is performed for three times according to the operating instruction of the tissue masher until homogenate is completely suspended, and the tissue homogenate is transferred to a plastic drum; glacial acetic acid is added into the tissue suspension plastic drum to regulate the concentration of the solution to be 0.5 milligram / milliliter. According to the method, the pasty liquid obtained by processing the cowhide is used for collagen extraction, and therefore the purification rate and purity of the collagen can be obviously improved.

Description

technical field [0001] The invention belongs to the technical field of biological food. Background technique [0002] Collagen is the most abundant protein in the human body, accounting for more than 30% of the total protein in the body. Collagen is rich in amino acids such as glycine, proline, and hydroxyproline that the human body needs. Collagen is the most important component of the extracellular matrix. Collagen has been eaten and used as a beauty filling material because it has the functions of firming and wrinkling, moisturizing, repairing tissue, whitening and blemishes; collagen is generally extracted from pigskin and cowhide, and currently it is extracted from cortex There are many methods for protein, but due to the rough treatment of the cortex in the early stage of the existing process, the purification rate and purity of collagen are seriously affected in the later stage, thus affecting its application value.
