Process for preparing composite high-protein antibacterial peptide

The present invention relates to the preparation process of one kind of composite high protein antibacterial peptide. One or several kinds of soybean, rice, corn, milk and other animal and plant protein powder or liquid is mixed with maggot protein or liquid; the mixture is fermented in biological converting liquid and filtered to obtain filtrate; and the filtrate is concentrated at normal temperature and bottled or spray dried at normal temperature and bagged. The said process can obtain active bacterial protein with all the functions of available protein peptide and growth promoting factor, and the composite high protein antibacterial peptide can promote digestion and absorption, resist virus and pathogenic bacteria and raise immunity. The composite high protein antibacterial peptide may be used widely in food, health article, feed additive, etc. and especially in medicine.
