Production technique of bone peptide calcium

Abstract

The invention relates to a manufacturing technique of bone protein peptide calcium, comprising the following steps: (1) beast and bird bone is made into minced bone which is used as hydrolyzing substrate; (2) pH value is adjusted to 5-7, ossein enzyme is firstly used, common proteinase is then used for hydrolyzing, and temperature is risen for killing enzyme; (3) bone protein hydrolyzing liquid is filtered, the filtered liquid is dried after membrane filtration, and bone protein peptide powder can be obtained; filter residue is dissolved by adding acid, then the solution is filtered and dried, and bone calcium phosphate powder can be obtained; at last, the bone protein peptide powder and the bone calcium phosphate powder are mixed to obtain the bone protein peptide calcium powder. The invention has the following advantages: firstly, the absorption for a human body is easy, and the calcium-phosphorus ratio is 2 to 1 which is reasonable, and the bone protein peptide calcium is favorable calcium enriching product; secondly, the nutrition is abundant, in the bone protein peptide calcium of the product, the content of total protein is 10.38 percent, the content of the bone protein peptide is 8.56 percent, the content of the calcium is 6.16 percent, and the content of the phosphorus is 2.73 percent.

Description

Technical field: [0001] The invention belongs to a preparation method of nutrition and health products, in particular to a production process of bone protein calcium. Background technique: [0002] Because bone is an ideal cheap protein resource, and the processed products have high economic value and nutritional and health effects, livestock and poultry bones have been processed into bone powder, bone paste, etc. abroad and applied to sausages, bread and other foods as nutritional fortification Drugs or further processed into health care products for sale to meet people's growing needs. However, since the main component of protein in livestock and poultry bones is collagen, the collagen molecule has a unique 3-strand superhelical structure, that is, each of the 3 polypeptide chains forms a left-handed rotation to the left, and the 3 peptide chains are then The hydrogen bond interlocks to form a firm right-handed superhelix. This superhelix structure is very stable. It cann...

AI Technical Summary

Problems solved by technology

Proteases belonging to hydrolytic enzymes occupy an important position in the food industry, but at present, the production of calcium supplement products of bone protein hydrolyzate in my country is relatively small, and there are still shortcomings such as low content of small molecular peptides, poor solubility, and low human absorption rate.
