A preparation method and application of bone marrow protein and polypeptide

Abstract

The invention relates to a bone marrow protein and polypeptide ultrafiltration membrane preparation method and an application thereof. Fresh bone marrow in animal bones in a slaughter house for cattle, sheep, horses, camels or other animals serves as a raw material, the bone marrow and bones are classified, cleaned with clear water, frozen by liquid nitrogen and crushed to obtain bone marrow powder, warm water solution is used for extraction, grease components are sufficiently degreased, and the protein with the molecular weight cut-off of 10KDa is prepared by modern ultrafiltration membrane technology and then refined by modern spray drying technology or freeze-drying. The antibacterial and antifungal activity of the bone marrow protein is verified, and the bone marrow protein has wide antimicrobial activity, has the function of enhancing humoral immunity and general immunity and is rich in human easily digestible and absorbable pure natural plant source polypeptide and protein. The protein has the advantages that original protein of the bone marrow is retained, waste is turned into wealth, resources are sufficiently used, and the protein serving as a natural antibacterial agent, a food additive or a medicine can be used for food and pharmaceutical industries.

Description

Technical field

[0001] The invention relates to a method for preparing bone marrow protein and polypeptide and its application. It is a protein with antibacterial activity prepared by using Xinjiang's resource-rich bones as raw materials. It has antibacterial, antifungal and other biological activities, and is very useful in the fields of medicine and food. Good application prospects. Background technique

[0002] my country is a big country of livestock and poultry consumption, but it is mostly concentrated on the consumption of livestock and poultry meat. "A large amount of livestock and poultry bones cannot be used" not only wastes this nutrient-rich and reasonable ratio resource", but also pollutes the problem of bone treatment. The "environment" caused a certain environmental pressure.

[0003] The utilization of protein in the bones of livestock and poultry, bone protein, the protein content in bone is very high, and it is a relatively complete soluble protein, and the biolog...
