Abstract: A fundamental pattern was proposed for rapid autolysis of scallop disposal from processing by a series of experiments on factors of UV radiation, mineral ions, pH value and temperature. It was found that there was the maximal amino acid nitrogen concentration （3. 389 g/L） in the scallop disposal solution under 40 min UV radiation ; good autolysis was observed at pH value of 7.0; the rate of autolysis was accelerated at 60℃ or a gradient temperature of 5℃/h from 40℃ 5 to 65 ℃ ; The rate of hydrolysis for scallop disposal increased at Na ion of 0.07 mol/L and Ca ion of 0.03 mol/L while there was no significant effect of Zn ion concentration on the rate of autolysis. The amino acid nitrogen of 4. 006 g/L was found in the hydrolysate under the optimal autolytic conditions for 3 hr. The analysis of molecular distribution of the autolyzed hydrolysates by SephadexG - 15 resin showed that the molecules primarily consisted of small molecular peptides with the molecular weight of about 784.25 Da, which can be used as essential part of the nutritious and delicate fishery seasonings.
