Experiments were conducted to investigate the effects of household processing on removal of acephate, profenofos and triazophos residues in brinjal. Brinjal crop was raised in the field and sprayed with insecticide at recommended rate (RR). Brinjal fruit samples were collected at 1, 3 and 5 day interval after spraying and subjected to household processings like washing with tap water, salt water washing (2% NaCl), lukewarm water washing, open pan cooking and microwave cooking after processing brinjal fruits were analysed by QuEChERS method and insecticide residues were estimated by GC-FPD. Washing processes of brinjal fruits provided 21.95-54.54 per cent relief from acephate, 22.10-61.40 per cent relief from profenofos and 20.00-61.81 relief from triazophos residues. Open pan cooking provided 52.43-56.97 per cent, 52.63-68.42 per cent and 50.21-67.27 per cent relief from acephate, profenofos and triazophos residues, respectively. Microwave cooking provide higher relief from residues in compariso to the other processes like washing and open pan cooking.
