用水产下杂鱼鱼为原料料进行酶解 ,采用反向高效液相色谱法测定了酶解产物的游离氨基酸和水解氨基酸 ,并用凝胶色谱法对酶解产物的多肽分子量分布进行了测定。发现其总蛋白质为 72 0 5% ,其中游离氨基酸占 15 0 4 % ,其余为多肽分子混合物。必需氨基酸占总氨基酸的 38% ,赖氨酸和牛磺酸含量丰富。酶解产物可望开发成蛋白质补剂或功能食品 The fish was used as raw material to carry on the enzymolysis, the free amino acids and hydrolyzed amino acids of the hydrolyzate were determined by reverse-phase high performance liquid chromatography, and the molecular weight distribution of the hydrolyzate was determined by gel chromatography . Total protein was found to be 72 0 5%, of which 15 0 4% were free amino acids and the rest were peptide mixtures. Essential amino acids account for 38% of total amino acids, and lysine and taurine are abundant. Enzymatic hydrolysis products are expected to develop into protein supplements or functional foods
