This study was undertaken in order to elucidate the elimination of fenitrothion residues during the dietary fiber and bioflavonoid preparations from mandarin orange peels. Dietary fibers were prepared from contaminated mandarin orange peels through homogenization, enzyme treatment, ethanol precipitation, acetone washing and air drying, at the yields of 17.4% total dietary fiber, 13.1% insoluble dietary fiber and 1.7% soluble dietary fiber. The removal rate of fenitrothion residues at 13 and 0.5 ppm levels in orange peels was 98.4% and 91.9% in total dietary fiber, 99.7% and 97.1% in insoluble dietary fiber, 100% and 99.6% in soluble dietary fiber, respectively. When bioflavonoid was prepared from contaminated mandarin orange peels through homogenization, soaking, ethanol precipitation, hexane and butanol extractions, the removal rate of fenitrothion residues was 92.7% in intermediate extract and 100% in final extract.
