Preliminary Research on Sterilization Effect of Chinese Patent Medicine by Nanosecond Pulsed Electric Fields

Abstract:

Objective: To investigate sterilization effect on Chinese patent medicine by nanosecond pulsed electric fields. Method: Taking Dashanzha pills,Shuxin syrup and Yimucao pastes as research objects,field strength was 40,50,60 kV· cm^-1 and pulse frequency was 10,100 times,by interaction of these two parameters,Chinese patent medicine was electric shocked by nanosecond pulsed electric fields generator,sterilization effect was detected by plating method. Result: Sterilization by nanosecond pulsed electric fields was effective to Shuxin syrup and Yimucao pastes while invalid to Dashanzha pills. Conclusion: Sterilization is effective to liquid and semi-solid Chinese patent medicine by nanosecond pulsed electric fields.
