为评估新型杀菌剂——中性氧化电位水的应用性能,对其稳定性、安全性进行了研究,并与过氧乙酸、二氧化氯、双氧水对比分析了中性氧化电位水对金属腐蚀性的影响和其杀菌性能。结果表明,中性氧化电位水在密闭、避光条件下稳定性良好;浓度为0.5%~5%的中性氧化电位水对啤酒老化无显著影响,对啤酒风味无安全隐患;浓度低于5%的中性氧化电位水对铜、铝、不锈钢(304和316)、碳钢涂层T541基本无腐蚀,浓度为1.5%的中性氧化电位水可有效杀灭2×(106~107)CFU/mL的单一污染菌和混合菌。

In this paper,we focused on the stability and security of Neutral Electrolyzed Oxidizing Water( NEOW),which is a new kind of bactericide,and evaluated theapplication performance. By choosing acetic acid peroxide,chlorine dioxide and hydrogen peroxide as references,we analyzed the influence of NEOW on metal corrosion and test its bactericidal performance. The experiments proved that NEOW had good stability under the sealed and dark condition. If the concentration of NEOW was 0. 5% ~ 5%,there was no significant influence on beer aging,while no adverse effects on beer flavor were found. NEOW with the concentration lower than 5% barely corrodes copper,aluminum,stainless steel 304,stainless steel 316 and tank steel coating T541. When the concentration was 1. 5%,NEOW could effectively sterilize single bacterium or mixed microorganisms in 2 ×( 106~ 107) CFU/mL.
