Abstract
By using Aspergillus sp. acid protease, the preparation of skin secretion hydrolysates from giant salamander (Andrias davidianus) was studied. Through orthogonal test, the optimum hydrolytic condition as follows: temperature 55°C, pH2.0, E/S value is 0.03%, and hydrolysis time 3h. MALDI-TOF mass spectrometry showed that molecular weights of hydrolysates were below 3.5kDa.
