毒死蜱常用来防治水稻上的主要害虫,会在稻米上残留并造成潜在危害。研究残留毒死蜱在稻米加工过程中的消解规律,阐明不同烹饪方式对稻米中残留毒死蜱的影响。采用清洗、蒸煮、煮粥、蒸煮后再炒饭等加工方式对稻米进行加工,研究表明清水清洗能有效去除稻米上残留毒死蜱,随着清洗次数的增加,去除效果更加明显,清洗3 次后去除率达到64.54%,加工因子为0.3546。而家庭烹饪方式能有效去除稻米中的残留毒死蜱,蒸煮后稻米中残留毒死蜱的去除率为87.83%,加工因子为0.1217;煮粥后,稻米中毒死蜱的去除率为96.07%,加工因子为0.0395;蒸煮后再炒饭,稻米中毒死蜱的去除率为98.35%,加工因子为0.0165。在上述3 种加工方式中,残留的毒死蜱会降解产生3,5,6- 三氯-2- 羟基吡啶。 |
英文摘要: |
Chlorpyrifos is commonly used to control rice pests,but it will residue on rice and cause potential harm.
Degradation dynamics study of chlorpyrifos residues on rice during processing could provide an instruction for removal
efficiency of chlorpyrifos on rice during different processing methods. Rice processing methods such as cleaning,
cooked,porridge,cooked and then fried were used to remove the chlorpyrifos residues on rice and their removal effects
were evaluated. Tap water could effectively remove the chlorpyrifos residues on rice. With the increase of cleaning time,
the removal effect was obvious. After washed for 3 times,the removal rate of chlorpyrifos residues was 70.29% and the
processing factor was 0.2971. Home cooking could effectively remove the chlorpyrifos residues on rice. The removal
rate of chlorpyrifos residues in boiled rice was 87.83% and the processing factor was 0.1217. The removal rate of the
chlorpyrifos residues on porridge was 96.07% and the processing factor was 0.0395. The removal rate of chlorpyrif residues on fried rice was 98.35% and the processing factor was 0.0165. But the chlorpyrifos residues would degrade into 3,5,6-trichloro-2-hydroxy-pyridine. |
