二元制剂二氧化氯消毒剂对瓜果蔬菜消毒效果的研究

Research on disinfection effect of chlorine dioxide disinfectant on vegetables and fruits

目的:了解二元制剂二氧化氯消毒剂的部分杀菌性能。方法:采用悬液定量杀菌试验和模拟现场鉴定试验方法进行了实验研究。结果:含二氧化氯100 mg/L该消毒剂溶液对悬液内大肠杆菌作用5 min,杀灭对数值大于5.00;用含100 mg/L二氧化氯消毒液浸泡消毒黄瓜,作用15 min,对黄瓜上污染的大肠杆菌的杀灭对数值各样本均≥3.00。结论:该二氧化氯消毒剂对大肠杆菌有较好的杀灭效果,可以用于瓜果蔬菜消毒。

Objective： To understand the bactericidal performance of chlorine dioxide disinfectants. Methods： Suspension quantitative germicidal test and simulated field identification test were involved in this study. Results： Escherichia coli in suspension and poison cucumber were killed by disinfectant solution including 100 mg/L chlorine dioxide in 5 min and 15 min respectively, with killing log value all above 3.00. Conclusion： The chlorine dioxide disinfectant had good effectiveness of killing, so it can be applied to disinfection of vegetables and fruits.
