According to the peptide content,the collection of enzymes for jellyfish was carried out,hydrolyzation of Flavourzyme and fungal acid protease were better than the other enzymes. The results of single factor experiment showed that when the substrate concentration was 2%,the better hydrolysis conditions of Flavourzyme and fungal acid protease were 45℃,pH6.0,enzyme dosage 2700U/g and 55℃,pH2.5,enzyme dosage 2000U/g,hydrolyzation time 90min,respectively. Under these conditions,the peptide extraction rate was 62.5% and 74.7%,respectively.
