The efficiencies of rice-bran for removing pesticides from vegetables was studied. Chlorothalonil was successfully removed from commercial eggplant and cucumber with an average removal efficiency of 95% after 5 min when vegetables were pickled in rice-bran paste. Moreover, tetradifon was removed from commercial eggplant, commercial cucumber, and cultivated cucumber with an average removal efficiency of 80% after 10 min. The mechanism of pesticides removal by rice bran was attributed to the uptake of pesticides into intracellular particles called spherosomes.
