Removal of Pesticide Residues in Farm Productsby Ultrasonic Washing (part 2)

Abstract

In this study, we examined the utilization of washing by ultrasonic waves for reduction of four pesticide residues on surface of strawberry and grape in order to reduce a risk on pesticide residues to consumer. The removal rates was high in the order of acetamiprid, diethofencarb, chlorfenapyr and pyridalyl according to solubility in water. In particular, it was found that appending powderly activated carbon in proper quantity was effective on improvement of removal rate of pyridalyl which is water-insoluble.
