Preparation of hydrolyzed animal protein from chicken bone paste with Alcalase

Xuehong Li

Abstract

Fresh chicken clay was hydrolyzed by Alcalase.The result showed that optimal conditions for hydrolysis were preheating treatment 90 ℃ for 30 min,chicken clay suspension concentration 10%.At the temperature of 60 ℃,pH=9.5 for 2.5 h,enzyme dosage is 6 000 U/g,degree of hydrolysis is up to 17.3%.Enzymatic hydrolysis is yellow,fragrant and suitable for chicken flavor.
