摘　　要：在实验室模拟浸染农药条件下,研究了经清水浸泡、流动水冲洗、超声波清洗、热水浸泡、臭氧水清洗5种清洗方法以及磨油处理后,联苯菊酯、2,4-二氯苯氧乙酸、咪鲜胺、螺螨酯、水胺硫磷5种农药在脐橙全果中的残留量变化情况。结果表明,5种清洗方式对脐橙全果中的农药残留均有不同程度的去除效果,各农药的加工因子为(0.2989±0.0320)~(0.8996±0.0345),其中臭氧水清洗对农药的去除效果较好。5种清洗方式结合磨油处理均能显著降低脐橙全果中农药残留量,加工因子为(0.0008±0.0015)~(0.2328±0.0107),只有未磨油脐橙全果的0.10%~27.19%,其中臭氧水结合磨油法对农药的去除效果最好。研究结果对后续脐橙全果产品加工的质量安全控制提供参考。The effects of different cleaning methods combined with grinding oil treatment on the removal of pesticide residues from whole navel orange were investigated.Changes of five pesticide residues(bifenthrin,2,4-Dichlorophenoxyacetic acid,prochloraz,spiromethrin,and amiphos)from whole navel orange by five different cleaning methods(immersing with clean water,rinsing with running water,cleaning with ultrasonic,immersing with hot water and cleaning with ozone water)were studied under laboratory conditions.The results showed that these cleaning methods all could remove pesticide residues with varying degrees in whole navel orange samples.The processing factors of each pesticide varied in the range of(0.2989±0.0320)-(0.8996±0.0345).Ozone water cleaning had a better removal effect on pesticides among them.After five cleaning methods combined with grinding oil treatment,pesticide residues on whole navel orange samples were significantly removed.The processing factors were(0.0008±0.0015)-(0.2328±0.0107),only 0.10%-27.19%of the whole navel orange with no grinding oil.Ozone water combined with grinding oil was proved to be the most effective pesticide removal method.The research results provide a reference for the quality and safety control of the subsequent processing of whole navel orange products.
