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.
