高压脉冲电场对大豆胰蛋白酶抑制剂的钝化效果

Effect of High Intensity Pulsed Electric Field on Inactivation of Soybean Trypsin Inhibitor

研究了高压脉冲电场对大豆胰蛋白酶抑制剂的钝化效果。结果表明:随着脉冲强度和脉冲处理时间的延长,大豆胰蛋白酶抑制剂活性下降,但效果不太显著。当脉冲电场和加热联合使用时,可以明显地钝化大豆胰蛋白酶抑制剂的活性,尤其是先脉冲处理后加热钝化效果更为显著。

Effect of high intensity pulsed electric field （PEF） on inactivation of soybean trypsin inhibitors（STU was studied in this paper. The result showed that tile activity of soybean trypsin inhibitors was decreased with the increment of the pulsed electric field intensity and the prolongation of treatment time with a less obvious effect. When the combination of pulsed electric field and heating treatment, soybean trypsin inhibitors were obviously inactivated, especially for pulsed electric fieM treatment before heating treatment.
