Process for preparing bird's nest polypeptide and use

Abstract

The present invention provides a preparation process and use of bird's nest polypeptide obtained through degrading bird's nest protein with composite ficin. The preparation process includes freeze drying fresh bird's nest, crushing into powder, degrading bird's nest protein with ficin, freeze precipitating, filtering, sterilizing and freeze drying to obtain bird's nest polypeptide. The bird's nest polypeptide is superior to bird's nest in nutrients, absorption rate, utilizing rate and protein synthesizing rate, and may be used as medicine material, medicine, health article, food or food additive. The present invention has simple technological process, low cost and high benefit, and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of bioactive peptides, and uses ficin to degrade bird's nest protein to obtain bird's nest polypeptide. Background technique [0002] In recent years, with the improvement of people's living standards, people's requirements for high-grade supplements have increased. Therefore, a lot of research and innovation have been carried out on the preparation and eating methods of bird's nest at home and abroad. Even so, the macromolecular protein of bird's nest is not easily absorbed by the human body and the problem of being utilized by human tissues has not been resolved. The invention utilizes ficin to degrade the macromolecular protein of bird's nest, so that the human body can easily absorb and utilize it, and synthesize human protein at a high rate in the human body, which is of great significance to human health. Contents of the invention [0003] The invention discloses a preparation method and application of bird's...
