大豆中胰蛋白酶抑制剂的钝化方法研究
Research on the Passivation Methods of Soybean Trypsin Inhibitor
摘要
Abstract
[Objective]To passivate the trypsin inhibitor in soybean,reduce its activity and increase the nutrient value of soybean feeds. [ Method ] Orthogonal experiment was adopted to compare the chemical (sodium sulfite method) and physical (microwave and ultrasonic method) passivation method,and determine the optimum passivation conditions. [Result]The optimal conditions for chemical passivation were:0.03 mol/L Na2SO3,75℃,and 60 min. The optimal conditions for microwave passivation were;240W microwave power,90 s.and 60 mesh sieve. The optimal conditions for ultrasonic passivation were:30 ml water,30 min and 60 mesh sieve. [ Conclusion ] The activity of soybean trypsin inhibitor which was passivated with the three methods was significantly lowered.关键词
