Results Different concentrations of vinegar with different disinfection duration showed significantly different bactericidal effect on Staphylococcus, Escherichia and Candida albicans (F=6.89~156.83, P.05). The effect was better along with higher concentration and longer duration. The average kill rate against natural bacteria on hands was 0.9915±0.0032 after exposed to vinegar solution for 2 min. The average kill rate against natural bacteria on kitchenware, such as table top, chopping block, knife, cupboard, porcelain bowl and the surface of refreshing box of the refrigerator were all above 0.9720 when cleaning and polishing with vinegar solution for 10min. The bactericidal efficacy of vinegar against natural bacteria in room air was enhanced with fumigating duration prolonged (F=1212.13, 5024.46; P.05), while lowered when there were persons in it (t=5.08-30.48, P.05). The content of acetic acid in vinegar dropped by 8.372 g/L when it was stored at 54℃(relative humidity 0.75) for 14 days.

结果 不同浓度的食醋溶液作用不同时间对金黄色葡萄球菌、大肠杆菌和白色念珠菌的杀灭效果不同，浓度越大、作用时间越长杀菌效果越好(F=6.89~156.83，P.05)；对手自然菌作用2min，平均杀灭率为0.9915±0.0032；对厨房内台面、砧板、菜刀、碗柜、瓷碗、冰箱保鲜室表面擦拭消毒10min，对自然菌的平均杀灭率在0.9720以上；对室内空气自然菌的杀灭率随熏蒸时间的延长而提高(F=1212.13、5024.46，P.05)，当室内有人时，杀灭率有所降低(t=5.08~30.48，P.05)；置于54℃恒温箱（相对湿度≥0.75）存放14d，醋酸总含量下降
