高浓度臭氧水对柑橘多菌灵的降解及其精油品质的影响

Degradation of cabendazim on citrus and effect of essential oil qualety by the high concentration of ozone water

利用高浓度臭氧水降解柑橘表面的多菌灵(N-(2-苯骈咪唑基)-氨基甲酸甲酯),并研究降解过程对柑橘精油品质的影响。结果表明:自来水和高浓度臭氧水均能降解柑橘上的多菌灵农药,高浓度臭氧水对多菌灵的降解率是自来水的1.72倍,经11mg/L臭氧水流动漂洗15min,多菌灵的降解率达86.3%;高浓度臭氧水处理的柑橘皮中的多菌灵大部分在前10min内降解。高浓度臭氧水在降解农残同时,并不影响柑橘精油品质。

Used high concentration of ozone water to degradation the carbendazim （N-（2-imidazole truxene base）-methyl carbamate ） on the surface of the citrus, and studyed the influence of the degradation process of citrus essential oils quality. The results： the tap water and high concentration ozone water could degrade carbendazim pesticide on citrus, and the degradation of high concentration ozone water rate was 1.72 times as great as tap water, the degradation rate reached 86.30% with 11 mg/L ozone water for 15 rain. Most of carbendazim on the citrus was degraded in the first 10 minutes by the high concentrations of ozone water. At the same time of the degradation process, the high concentrations of ozone water did not affect the quality of citrus essential oils.
