Biocollagen and its production process

Abstract

The biocollagen with bioactivity is extracted form animal skin. The production process includes; selecting skin of health fragrant hog in 3 month age, eliminating hair and fat; sterlilzing, water washing, steaming in physiological saline at 30-40 deg.c temperature and 0.2-0.4 MPa pressure for 2-4 hr, extracting and degrading collagen at high temperature, filtering to purify, separating to eliminate fat and grease, freeze drying to dewater, and forming. The biocollagen has excellent bioactivity, good biocompatibility to human body, fast hemostasis function, no allergy, no stimulation, no toxic side effect, no rejection, easy absorption in human body and fast wound repairing function.

Description

(1) Technical field:

[0001] The invention relates to gelatin extracted from animal skin, also known as protein collagen, in particular to biologically active biological collagen, and a production process for the above-mentioned collagen. (two) background technology:

[0002] The protein collagen extracted from animal skin is called gelatin for short. It can be extracted from animal bone and skin. In fact, it is the first-class bone glue and skin glue with light color, high transparency and high purity. Existing gelatin all adopts common pigskin as raw material, and the application number as the inventor's application is 981046223, and the name is called "the technique of producing medicinal gelatin with broken leather" and the application number is 03117311.x, and the name is "biological absorption Hemostatic cotton and its production process" invention patent. Because ordinary pigskin is thick and hard, it must be soaked in alkaline solution such as lime water to make it f...
