Effect of ozone on the reduction of pesticide residue in baby corn (Zea mays L.)

Effect of ozone on the reduction of pesticide residue in baby corn (Zea mays L.) was studied. Baby corns were dipped in the solution of standard chlorpyrifos at a concentrations of 10 mg/L for 10 min. They were exposed to ozone gas (O3) and dipped in ozonated water at concentration of 200 mg/L for 1...

Description
Summary:Effect of ozone on the reduction of pesticide residue in baby corn (Zea mays L.) was studied. Baby corns were dipped in the solution of standard chlorpyrifos at a concentrations of 10 mg/L for 10 min. They were exposed to ozone gas (O3) and dipped in ozonated water at concentration of 200 mg/L for 15, 30, 45 and 60 min. The results showed that both ozone gas and ozonated water could reduced pesticide residue in baby corns. Dipping in ozonated water for 60 min. was more effective than exposing to ozone gas with the degradation percentage of pesticide residue at 68.35 and 31.87%, respectively. The second experiment, baby corns were exposed to ozone gas and dipped in ozonated water for 60 min. and then stored at 10°C for 21 days. During storage time when compared with control, All methods were not significantly different in losing weight, color change, total soluble solid (TSS) and browning. Moreover, after storage time for 21 days, it was found that pesticide residue degradation was increased from 12.38 to 21.88% and 65.81 to 77.92% in which exposed to ozone gas and dipping in ozonated water, respectively.
