Production process of whole silkworm chrysalis powder containing lactoferrbumin and its peptide

Abstract

The invention is a method of producing all-pupa powder containing lactoferrin and its peptide, adopting bacilliform viruses as carrier, and using silkworm pupas as host to produce the gene engineering product with the bioactivity similar to that of the natural lactoferrin and the corresponding peptide. The producing and using course is safe and has no latent danger to human beings and animals and the environment. The all-pupa powder acting as feed additive can supplement feed proteins and simultaneously play a role in sterilizing and resisting viruses, and enhancing self-immunity of animals, and can effectively prevent and cure the diarrhea of weaner piglets, thus producing a high-quality animal product without residual antibiotics.

Description

technical field

[0001] The invention relates to a preparation method of whole silkworm chrysalis powder containing lactoferrin and its peptide. Background technique

[0002] Lactoferrin (Lactoferrin referred to as LF), isolated from milk in 1960, is an iron-binding glycoprotein with a molecular weight of about 80KDa. LF has the effect of transporting iron ions and sterilizing and antiviral. Its expression level in mammary glands The highest, and the highest content in human milk, the content in cow's milk is relatively small. Its unique mechanism of action has attracted people's attention, and it is separated and purified from milk and added to infant milk powder. Lactoferrin peptide (Lactoferricin, referred to as Lfcin) is the product of lactoferrin degraded by protease in the digestive tract of animals, and some of its biological activities are stronger than lactoferrin. Whole silkworm powder is rich in nutritional value and has some special eff...
