【摘要】 观察纳米银对中西餐厨房餐饮具的消毒效果。以细菌总数、大肠杆菌数作为检测指标,研究5个浓度的纳米银对中餐厨房餐饮具(抹布、不锈钢操作台、不锈钢盆、工作服、不锈钢刀具、塑料菜板及地板)的消毒效果。通过测定中西餐厨房餐饮具的细菌总数和大肠杆菌数,比较0.05 mg/L纳米银与250 mg/L含氯消毒液、紫外臭氧的消毒效果。结果表明纳米银的最低有效杀菌质量浓度是0.05 mg/L。0.05 mg/L纳米银对餐饮具的消毒效果优于250mg/L含氯消毒液,极显著优于紫外臭氧的消毒(p<0.01)。更多还原

【Abstract】 The research aims to observe the disinfection effect of silver nanoparticles(Ag NPs) on Chinese and Western kitchen utensils. Based on the total number of bacteria and Escherichia coli, this research discussed the disinfection effects of five different concentrations of Ag NPs on Chinese kitchen utensils(dishclothes, stainless steel table, stainless steel basin, work clothes, stainless steel cutter, plastic chopping board and floor). By measuring the total number of bacteria and E. coli of Chinese and Western kitchen utensils to compare the disinfection effect of 0.05 mg/L Ag NPs, 250 mg/L chlorine disinfectant with ultraviolet ozone disinfection. The minimum effective bactericidal concentration of Ag NPs was 0.05 mg/L. And the effectiveness of 0.05 mg/L Ag NPs on the kitchen utensils was better than 250 mg/L chlorine disinfectant, extremely significantly better than ultraviolet ozone disinfection(p<0.01).更多还原
