摘要
为了优选鲍鱼杀菌的最佳工艺条件,采用臭氧水进行杀菌处理,利用单因素试验研究料液比、臭氧水浓度、杀菌时间和温度对菌落总数的影响,结果表明:当料液比1∶7~1∶9、臭氧水浓度2.0~3.0 mg·L^(-1)、杀菌时间7~9 min、臭氧水温度70~15℃时,鲍鱼经臭氧水杀菌能保持较理想的微生物水平。基于单因素研究结果,通过响应面优化法确定最佳工艺条件,得到鲍鱼臭氧水杀菌的最佳工艺条件为料液比1∶7、臭氧水浓度2 mg·L^(-1)、杀菌时间7 min、臭氧水温度9℃,为臭氧水对鲍鱼杀菌技术的进一步优化提供了理论基础。
In order to optimize the best technological conditions for the sterilization of abalone,the ozone water was used for the sterilization treatment,and the effects of the solid-liquid ratio,ozone water concentration,sterilization time and temperature on the total number of colonies were studied by using the single factor test.The results showed that when the ratio of solid to liquid was 1∶7-1∶9,the concentration of ozone water was 2.0-3.0 mg·L^(-1),the sterilization time was 7-9 min and the temperature of ozone water was 70-15℃,the optimal microbial level of abalone could be maintained by the sterilization of ozone water.Based on the results of single factor study,the optimal technological conditions were determined by using the response surface optimization method.The optimal technological conditions for the sterilization of abalone by ozone water were obtained as follows:the ratio of solid to liquid was 1∶7,the concentration of ozone water was 2 mg·L^(-1),the sterilization time was 7 min,the temperature of ozone water was 9℃,which provided a theoretical basis for the further optimization of ozone water sterilization technology for abalone.
