Technology for Enzymolysis of Fresh Bones ofDomestic Animals and Poultry with CompoundedEnzymes and Its Application

摘要

This paper is concerning about a kind of process which is used to produce functionaland natural compounded flavourings using waste fresh bones as raw materials of domesticanimals and poultry.The author throws light on enzymolysis process of domestic animals andpoultry’s bones with compounded enzymes.Five tests are made for comparison .Three of themuse single enzymes respectively such as trypsin,neutral protease ,alkaline protease.The othertwo tests uses compounded enzymes.It is proved that the enzymolysis effect of compoundedenzymes is superior to that of single enzyme.Main components of hydrolysates after enzymolysis process with compounded enzymes arecollagen multi-peptide,amino acids , and free active Calcium.These nuitrients have the functionssuch as protecting our gastric mucosa and improving gastric ulcer resistance,depressingblood-pressure rising, promoting collagen metabolism of skin,promoting the development ofskeleton and preventing osteoporosis.There are data showing that biological active peptide ,freeactive Calcium extracted by the process can be absorbed by man at the rate of 100%.There are up to ten million tons of domestic animals’ fresh bones as waste materials in a year infactories at home.Most of the waste bones are casted away,while a little bit of them areprocessed into feeds ,fertilizers,and etc.Here the author worked out the process with waste freshbones to produce compounded flavourings of many functions.It will not only add value to wastematerials in factories,but also protect our environment.
