The Effect of High Voltage Electric Field on а-Amylase’s Activity and the Study of it’s Uechanisms

Abstract

Abstract: This paper studied the effect of high voltage electric field on α-Amylase’s activity at different treatment electric field. ternperature and time. The results show that: when the temperature is 25℃ and the electric field is 22KV/cm, treat 30 seconds make the enzyme’s activity decreased by 60% , when the treatment temperature is 21℃ and electric field is 15 KV/cm, treat 1 min make the activity decreased by 30.8% , and 10 min by 45. 17%; when the treatment time is 30 seconds and the electric field is 15 KV/cm, treat at 21℃ make the activity decreased by 23. 55%, and 75C by 77.05%. The activity of treated sample significantly 10wer than the untreated one. The paper studied the mechanisms 0f the phenominens at the end
