Method for preparing novel silkie bone polypeptides

Abstract

The invention discloses a method for preparing novel silkie bone polypeptides. The method comprises the following steps: (1) cooking silkie bones in boiling water for 10-20 minutes, taking out the bones, and draining for later use; (2) grinding the silkie bones treated in the step (1) by adopting a grinder, and screening by using a 40-80-mesh sieve; (3) filling the silkie bone powder ground in the step (2) and water according to a ratio of 100-200g / L, wherein the temperature of enzymatic hydrolysate is 40-55 DEG C, adding trypsin according to the volume of the enzymatic hydrolysate after the temperature of the enzymatic hydrolysate is stabilized, ensuring that the concentration of the trypsin in the enzymatic hydrolysate is 1-4g / L, regulating the pH value of the enzymatic hydrolysate to be 8-9, regulating the pH value of the enzymatic hydrolysate to be 8-9 every 10-20 minutes, performing enzymolysis for 3-6 hours, and heating the enzymatic hydrolysate until the solution is boiling; (4) filtering the enzymatic hydrolysate obtained in the step (3), thereby obtaining the filtrate; and (5) heating and concentrating the filtrate obtained in the step (4), thereby obtaining the silkie bone polypeptides.

Description

Technical field: [0001] The invention relates to the development of a health care product, in particular to a preparation method of a novel black-bone chicken bone polypeptide. Background technique: [0002] Black-bone chicken (also known as bamboo silk chicken) is a kind of omnivorous domesticated bird. The United States calls it the smooth bantam, which is short, with a small head and short neck. After evolution and reproduction distribution, it is now found in many countries. Not only are their beaks, eyes, and feet black, but their skin, muscles, bones, and most of their internal organs are also black. Due to the different breeding environments, the characteristics of black-bone chickens are also different. There are white feathers and black bones, black feathers and black bones, black bones and black meat, white meat and black bones and so on. The color of black-bone chicken feathers also becomes more varied with the way of feeding. In addition to the original white...

Problems solved by technology

[0004] However, when people eat black-bone chicken, they only eat its meat, and its bones are thrown away as waste. In this way, a large amount of protein in black-bone chicken bones is discarded, which damages the environment in nature and is difficult to decompose.
