Decontamination of pesticide residues on tangerine fruit using non-thermal plasma technology

Abstract

© 2019 IOP Publishing Ltd. All rights reserved. Plasma Technology is a well-known approach to decontaminated not only pesticide residues but also fungus on fruits and vegetables. In the present paper, Non-Thermal Plasma (NTP) were successful generated via plasma activated water technique, pin hole. NTP were applied to decontaminated pesticide residues named, cypermethrin, on "Sai Num Pueng", tangerine fruit. A electrical power 125 watt and air flow rate 15L/min has been used. It was observed that cypermethrin concentration is significantly reduce from 1 ppm to 0.25 ppm which meet international food standard requirment (Codex standard). In particular, the NTP tangerine orange exhibits longer shelf-life as compared to the conventional tangerine orange. There are no significantly different related to appearance, acid flavor, sweetness and smell as also compared to conventional products.
