【摘要】 本试验以水解度为指标,研究了5种蛋白酶酶解虾加工下脚料的能力,确定了Flavourzyme和Alcalase为最佳复合酶。利用响应曲面法,得到了复合酶的最适酶解参数:起始pH值6.74,酶解温度48.3℃,底物浓度7.3%。在此优化条件下,重复试验3次,平均水解度达23.16%。更多还原

【Abstract】 According to the degree of hydrolysis,five different kinds of proteinase were studied on hydrolysis of the shrimp offal in this experiment.Flavourzyme and Alcalase were determined as the optimum mixed enzymes.Through response surface method,the optimum hydrolysis parameters of these mixed enzymes were figured out as follows : initial pH 6.74,temperature 48.3℃,substrate concentration 7.3%.Thrice repeat experiments were conducted under this condition and the degree of hydrolysis can reach 23.16%.更多还原
