摘要
为探究碱性电解水对罗非鱼的活体杀菌工艺,以鲜活罗非鱼为原料,评价碱性电解水p H值、盐度及处理时间对罗非鱼体表减菌率的影响,在单因素试验的基础上采用响应面试验优化杀菌工艺,得到最佳工艺条件:碱性电解水的p H值为10,盐度为8‰,处理时间为60 min。在此条件下罗非鱼体表减菌率高达94. 1%,表明碱性电解水对罗非鱼活体杀菌效果较强。
In order to explore disinfection technology of alkaline electrolyzed water for living tilapia,effects of p H value,salinity of alkaline electrolyzed water and treating time of tilapia in alkaline electrolyzed water on bacteria reduction rate of tilapia epidermis by using fresh tilapia were evaluated.On basis of single factor experiment,response surface method was used to optimize sterilization process,and optimal process conditions were obtained:10 of p H value of alkaline electrolyzed water,8‰of salinity,and 60 min of treating time of living tilapia in alkaline electrolyzed water.Under these conditions,bacteria reduction rate of tilapia epidermis was up to 94.1%,indicated that alkaline electrolyzed water has a stronger bactericidal effect on living tilapia.
