Abstract: The process of Trypsase,Alcalase protease and Papain hydrolysis of fresh antler velvet was investigated.Alcalase protease showed the highest degradation efficiency.it was founded that enzymatic concentration,hydrolysis temperature,pH and hydrolysis time were the main parameters which affect the degradation yield of fresh velvet antler.by single factor experiments.The optimal hydrolysis conditions were obtained by the orthogonal tests as follows: substrate concentration 0.08 g/ml,enzymatic hydrolysis temperature 65 ℃,pH 9.0 and hydrolysis time 6.0 h.Under the conditions,the degradation yield of fresh antler velvet is up to 92.6%,and the yield of the amino acids product reached to 12.1%.
