中性电解水对水产品接触的工器具杀菌效果

Germicidal efficacy of neutral electrolyzed water against the apparatus for the production of aquatic products

  • 摘要: 选取菌悬液浓度约为107CFU/mL致病菌金黄色葡萄球菌(Staphylococcus aureus)、福氏志贺氏菌(Shigella flexneri)、副溶血弧菌(Vibrio parahaemolyticus)、大肠杆菌(Escherichia coli)、鼠伤寒沙门氏菌(Salmonella typhimurium)进行杀菌及工器具消毒实验,考察中性电解水对染菌工器具的杀菌效果。结果显示,在2min内,中性电解水有效氯大于78.6mg/kg时,杀菌率均在98%以上。工器具染菌后,2min内,金黄色葡萄球菌、副溶血弧菌、大肠杆菌三种染菌基本全部被杀死。洗手消毒实验和舒适度调查表明,在30s内,中性电解水可将双手污染的250CFU/mL细菌活菌数量减少至5CFU/mL以下,且无味,对皮肤无刺激性。因此,中性电解水在水产品加工过程中可作为理想的消毒剂。 

     

    Abstract: In order to test the germicidal efficacy of neutral electrolyzed water against the apparatus used in aquatic products processing factories and Staphyloccocus aureus, Shigella flexneri, Vibrio parahaemolyticus, Escherichia coli and Salmonella typhimurium with respective concentrations of bacterial suspensions of 107CFU /mL were chosen as the subjects of the test. The results showed that within 2min, when the available chlorine in neutral electrolyzed water reached more than 78.6mg /kg, the bactericidal rates of all bacterial strains reached more than98%.The bacterial contamination and bacteriostatic tests showed that when the apparatus were contaminated, neutral electrolyzed water killed almost all three kinds of bacteria ( Staphylococcus aureus, Vibrio parahaemolyticus, Escherichia coli) within 2min. The handwashing sterilization test and the comfort survey of operators found out that neutral electrolyzed water could reduce the bacterial concentration from 250CFU /mL to 5CFU /mL within 30s and below; neutral electrolyzed water was odorless, non- irritating. Thus, neutral electrolyzed water could be used as the ideal sterilizer for aquatic food processing.
