谷氨酰胺转氨酶在鱼类加工副产品中的应用

Application of transglutaminase in fisheries by-products

以渔业加工中的废弃物——富含营养的鱼鳞、鱼鳍为材料,研究谷氨酰胺转氨酶在鱼鳞、鱼鳍提取物中的应用。结果表明,使样品达到最佳凝胶质构的条件是:酶添加1U/g样品、温度40℃、反应时间3h和pH5.0。结果显示谷氨酰胺转氨酶能显著地提高提取物的凝胶强度。

It took the by-products left in fish processing, which are full nutrient fish scale and fish fin as materials, and found out the application of transglutaminase in the extraction of fish scale and fish fin. The results are the followings： In the polymerization between transglutaminase and the free amino acid in the extractions of fish scale and fish fin, it indicated that the best conditions for its reaching the gel structure were those： enzyme with 1 U/g sample, temperature of 40 degree celsius, 3 hours of reaction time and pH5.0. The result showed that the transglutaminase could obviously increase the gel tenacity of the extraction.
