Optimization of a rice cooking method using response surface methodology with desirability function approach to minimize pesticide concentration

Rice is contaminated with pesticides applied in pre and post-harvest. These contaminations could be reduced through household operations like washing cooking. Therefore, the present research, a pre-soaking rice cooking method was used to reduce residues. Response Surface Methodology Central Composite Design minimize concentration by choosing best soaking time water:rice grain relation before A quadratic polynomial equation obtained. Desirability function approach gave optimal conditions as 14 h of 3. This process allowed pesticide elimination 100.0%, 93.5%, 98.4%, 98.5%, 99.0%, 95.0%, azoxystrobin, cyproconazole, deltamethrin, epoxiconazole, kresoxim-methyl penconazole, respectively.
