The present disclosure relates to a process for removal of pesticide residues from aqueous solutions and food products by ionizing radiation. Standard pesticides concentrations recognized by international organizations as maximum residues limit (MRLs) were used as the targeted concentrations in both aqueous solutions and food products. Commercially known pesticides and recommended irradiation doses by International Atomic Energy Agency (IAEA) were selected for this investigation. Aqueous solutions and food products fortified with pesticide residues were subjected to selected doses of ionizing radiation. Radiation-induced removal of pesticide residues is generally greater in aqueous solutions than in food products. Ionizing radiation can reduce the residues of pirimiphos-methyl in potatoes, grapes and dates; malathion and cypermethrin in grapes to below MRLs at the recommended irradiation doses.
本公开涉及一种通过电离辐射去除
水溶液和食品中农药残留的工艺。国际组织公认的最大残留限量(MRLs)标准农药浓度被用作
水溶液和食品中的目标浓度。本次调查选择了商业上已知的农药和国际原子能机构(IAEA)推荐的辐照剂量。对含有农药残留的
水溶液和食品进行了选定剂量的电离辐射。在
水溶液中,辐射诱导的农药残留去除率通常高于食品。在建议的辐照剂量下,电离辐射可使马铃薯、葡萄和椰枣中的
甲基吡啶磷残留量以及葡萄中的马拉
硫磷和
氯氰菊酯残留量降至最高残留限量以下。
