Reduction of pesticide residues from tomatoes by low intensity electrical current and ultrasound applications

The most effective conditions for reduction of captan, thiamethoxam and metalaxyl residues were 1400 mA + 40 kHz, 800 mA + 24 kHz and 1400 mA + 24 kHz, respectively. The residues of captan, thiamethoxam and metalaxyl were reduced in the order of 94.24%, 69.80% and 95.06% by using these combinations. EC and US strategies can be considered as effective treatments in industrial scale in order to remove the pesticide residues from vegetables.
