Abstract:
An experiment was conducted to evaluate the effects of some technological processes on the residual levels of profenofos, imidacloprid and penconazole in tomato fruits and products. According to their half-life (t (A1/2)) values, tomato fruits can be safely harvested for human consumption or for processing purposes 3 days after the spray time of imidacloprid and penconazole and 7 days after in the case of profenofos. Pesticide residues were greatly decreased in tomato juice under cold or hot break compared with that taken from unwashed tomato fruits. A sharp decline in profenofos level was noted after treatment by pectinex ultra SP-L and benzyme M during tomato crushing.
