摘　　要：文章旨在优化酸性电解水对罗非鱼片的杀菌工艺,开发一种新型的罗非鱼片减菌预处理方式。考察酸性电解水杀菌方式、氧化还原电位(ORP)、杀菌时间及料液比对罗非鱼片杀菌率的影响,采用单因素试验和正交试验优化杀菌工艺,并以过氧化氢作对照,评价酸性电解水的杀菌效果及其对罗非鱼片感官和质构的影响。结果表明:酸性电解水对罗非鱼片的最佳杀菌工艺条件为:浸泡方式,ORP 1163 mV,杀菌时间6 min,料液比3:80,在此条件下杀菌率可达98.0%;酸性电解水对罗非鱼片的杀菌率显著优于过氧化氢(P<0.05),酸性电解水能较好地保持罗非鱼片原有的色差和质构。The purpose of this article is to optimize the sterilization process of tilapia fillets with acidic electrolyzed water and develop a novel bacteria reducing pretreatment method for tilapia fillets.The effects of acidic electrolyzed water sterilization method,oxidation-reduction potential (ORP),sterilization time and material-liquid ratio on tilapia fillets were investigated.Single factor and orthogonal array design methods were used to optimize sterilization process,and hydrogen peroxide was used as a control to evaluate the sterilization effect of acidic electrolyzed water and its influence on the sensory and texture of tilapia fillets.The results showed that the optimal sterilization process for tilapia fillets was achieved under following conditions:soaking method,ORP 1163 mV,sterilization time 6 min,material-to-liquid ratio 3:80.Under these conditions,the sterilization rate of tilapia fillets reached 98.0%.The sterilization rate of acidic electrolyzed water on tilapia fillets was significantly higher than that of hydrogen peroxide (P<0.05).Acidic electrolyzed water can maintain the original color and texture of tilapia fillets.
