摘 要：鱼内脏中含有丰富的内源酶，利用内源酶能够水解鱼蛋白。水解鱼蛋白营养丰富，可用于制作糊、调味品和汤料，也可作为食品蛋白质强化剂。本课题主要研究以淡水鱼(以鲢鱼为例)内脏下脚料为原料,研究时间、温度、pH对提取效果的影响；得到最适提取条件为：pH7.5、温度22℃、时间3h。对无机盐离子对酶的激活作用进行试验，结果表明0.01mol/L的K+能够提高27.8%的酶活力。同时研究其保存条件，结果表明4℃，20℃条件下保存的酶液都产生腐败变臭，而-18℃条件下保存18天酶活力基本没什么变化。。通过单因素实验和正交试验研究各种因素对自溶水解效果的影响，得到最佳水解工艺条件为：提取pH7.5、时间8h、料液比1:2.5、温度50℃。

Abstract: The internal organs of fish are rich in endogenous enzyme, the use of endogenous enzymes to hydrolysis of fish protein. Nutritious fish protein hydrolysis can be used in the production of paste, spices and soup, but also can be used as food enhancer protein. The main research topics in order to freshwater fish (silver carp in the example) offal waste as raw materials, research time, temperature, pH effect on the extraction; be the optimal extraction conditions: pH7.5, temperature 22 ℃, time 3h. Of inorganic ions on the activation of the role of enzyme tests, results show that the 0.01mol / L of K + can increase the enzyme activity of 27.8 percent. At the same time, its storage conditions, results showed that the 4 ℃, 20 ℃ under the conditions of preservation of the enzyme changes are stinking corruption, and under the conditions of -18 ℃ to preserve for 18 days no changes in basic activity. . Through single-factor experiments and orthogonal test to study various factors on
