Problems solved by technology

[0005] Because bone collagen is the binder of calcium hydroxyphosphate molecules, the synthesis of collagen is slow and it is difficult to be replenished. The old collagen is continuously decomposed and degraded, resulting in bone calcium that cannot be fixed in a certain way and enters the blood, and then is eliminated from the body.

Abstract

The invention discloses a method for co-production of yak ossein peptide chelated calcium and bone polypeptide.The method comprises the steps of 1, extracting collagen polypeptide with the molecular weight of 2-4 KDa and other collagen polypeptide from yak bone; 2, chelating the collagen polypeptide with the molecular weight of 2-4 KDa obtained from the step 1 with Ca2+ to obtain yak ossein peptide chelated calcium, wherein during chelation, temperature is 50-55 DEG C, pH value is 6.8-7.2, and time is 1.5-2 h; 3, concentrating other collagen polypeptide obtained from the step 1 to obtain bone polypeptide.Technological operation is easy, equipment is simple and low in manufacturing cost, and the method is quite suitable for large-scale production.The method also provides strong technical support for high-valued processing of the yak bon resource in the Qinghai-Tibet Plateau.

Description

technical field [0001] The invention belongs to the technical field of bone processing, and in particular relates to a method for co-production of yak bone collagen polypeptide chelated calcium and bone polypeptide. Background technique [0002] Yak (Bos grunniens) is a very precious and rare livestock species in the world. It is mainly distributed in the Qinghai-Tibet Plateau, Tianshan Mountains, Altai Mountains, Sayan Mountains to the southeast of Lake Baikal. It is a famous landscape cattle species on the "roof of the world". Called Jacques, commonly known as yak abroad. Yaks have strong adaptability to the ecological environment conditions of alpine grasslands, and can live freely and reproduce in the harsh environmental conditions of thin air, short pasture growth period, and cold climate. It can use grasslands that ordinary livestock cannot use, and it is a primitive livestock breed that seldom competes with humans for food, living space and natural resources. There ...
