A bovine collagen peptide with functions of relieving fatigue and improving bone density and preparation method thereof

Abstract

The invention relates to the technical field of animal food processing, in particular to a bovine collagen peptide capable of relieving fatigue and improving bone density and a preparation method thereof. The preparation method of the bovine bone collagen peptide of the present invention comprises the following steps: using bovine bone as a raw material, enzymatically hydrolyzing the pretreated raw material to obtain an enzymatic hydrolyzate; the compound protease is neutral protease, papain and flavor Protease. The bovine bone collagen peptide prepared by the method has a high content of small molecular peptides; it has good water solubility, is easily absorbed by the human body, and has no bad smell; it has good effects of relieving fatigue and improving bone density; and the preparation method is simple and convenient to operate. Industrial production.

Description

technical field [0001] The invention relates to the technical field of animal food processing, in particular to a bovine collagen peptide capable of relieving fatigue and improving bone density and a preparation method thereof. Background technique [0002] The proportion of livestock and poultry bones to its body weight is 10% to 20%. The waste of livestock and poultry bones alone reaches tens of millions of tons every year. It is a very important by-product in the meat processing industry, but most of them are not fully utilized. Less than 2% is deep processed, resulting in great waste. Although the resources of livestock and poultry bones are very rich, the development and utilization of livestock and poultry bones is relatively backward. In addition to being directly used in ribs and cavity bones in daily diets and producing gelatin, there are also a large number of livestock and poultry bones that are processed into bone meal feed or traditional Raw materials and other...

Problems solved by technology

[0002] The proportion of livestock and poultry bones to its body weight is 10% to 20%. The waste of livestock and poultry bones alone reaches tens of millions of tons every year. It is a very important by-product in the meat processing industry, but most of them are not fully utilized. Less than 2% are processed, resulting in great waste

All of these have caused great difficulties to the development of bovine bone peptide with specific functions

Many bovine bone peptides in the prior art do not have specific functions, and there are very few bovine bone peptides that can relieve fatigue and improve bone density at the same time

In addition, in the prior art, during the enzymatic hydrolysis process, it is often necessary to add acid and alkali to adjust the pH, which not only increases the complexity and cost of the process, but also may affect the functional properties of the product and increase the ash content of the product.
