Abstract: Taking turkey ossein protein solution as materials, it researched on the primary factors which are influential in the ability of turkey ossein protein hydrolyzing, and optimized the conditions of enzyme hydrolyzing, and finally got the best conditions of oral liquid of turkey ossein peptide. The test shows the best enzyme hydrolyzing conditions of turkey ossein protein: reactant concentration is 10%, dosage of enzyme is 30μl/g, hydrolyzing temperature is 60℃ and the pH value is 7.0; the best conditions of oral liquid of turkey ossein peptide: turkey ossein peptide is 40%, Xylitol is 1.0% and honey is 5%.

Key words: turkey ossein protein, enzyme hydrolyzing, ossein peptide, oral liquid
