过氧醋酸消毒剂Peroxyacetic Acid SanitizerOne of the Most Effective Sanitizers Against Biofilms Biofilms and their consequences, with particular reference to hygiene in the food industry.Journal of Applied Bacteriology. 1993. 75, 499-511.Conclusion: The most effective of the products tested on biofilms was peracetic acid. Scientific Status Summary: Microbial Attachment And Biofilm Formation: A New Problem For The Food Industry. Food Technology. 1994. Vol. 48, No. 7, 107-114. Biofims Disinfection Development of a Microorganism Carrier-Surface Method.Sciences Des Aliments. 1992. Vol. 12, 721-728. The following are articles from scientific journals that indicateperoxyacetic acid sanitizers are most effective in controlling biofilms: 过氧醋酸的优点Peroxyacetic Acid Advantages 低泡 适合任何温度 结合消毒及酸性过水 不留残余物质 不会腐蚀不锈钢及铝 较能抵受有机污垢 不含磷 环保 杀菌力广泛 能于酸碱值达7.5发挥消毒效能 过氧醋酸 - 环保Peroxyacetic Acid, Environmentally Responsible 过氧醋酸 (Peroxyacetic Acid) 和 过氧化氢 (Hydrogen Peroxide) 分解 水 (Water) 氧 (Oxygen) 醋酸 (Acetic Acid) (Vinegar) 温度对消毒剂效能的影响Effect of Temperature on Sanitizer Efficacy 过氧酸 vs. 酸性消毒剂 酸碱度对消毒剂效能的影响Effect of pH on Sanitizer Efficacy 过氧酸 vs.酸性消毒剂 葡萄球菌 Staphylococcus aureus 大肠菌 Escherichia coli 3.0 pH 5.0 40oF 70oF 5 1 LOG REDUCTIONS LOG REDUCTIONS 5 1 过氧酸 酸 过氧酸 酸 过氧酸 酸 过氧酸 酸 Acid 过氧醋酸的缺点Peroxyacetic Acid Disadvantages 对金属离子敏感 腐蚀软金属 浓缩时有醋酸味 不能完全杀灭真菌 化学消毒剂杀菌力的比较Relative Antimicrobial Activity of Chemical Sanitizers % RELATIVE EFFICACY 革兰氏阳性 GRAM + BACTERIA 革兰氏阴性 GRAM - BACTERIA 酵母YEASTS 霉菌 MOLDS 过氧醋酸Peroxyacetic Acid “ 氯“ Chlorine “ 碘”消毒 Iodophors 酸性阴离子 Acid Anionics “ 季铵” Quats 消毒剂 vs. 微生物 热水Hot Water PMO (Pasteurized Milk Ordinance) - 最少摄氏170度 , 5 分钟 IDF (International Dairy Federation) - 最少摄氏185度 , 15 分钟 结合 “ 时间 ” 和 “ 温度” 是热水消毒 (Hot Water Sanitizing)最重要一环 热水的优点Hot Water Advantages 经济 容易供应 广泛杀菌能力 不含腐蚀性 渗透 * 正确选择的益处Benefits of “Making The Right Choice” 良好的口碑 减少财务损失 合乎法规的
