蛭弧菌混合体在三文鱼片制作过程中的应用

Application of Bdellovibrio mixture in production process of salmon slices

将蛭弧菌游泳体和蛭质体按1∶1比例混合制备的蛭弧菌混合体作为微生物制剂用于三文鱼生鱼片的制作过程,将加工初洗时的生鲜原料浸渍于蛭弧菌混合体中,并对操作台、加工车间和工具进行擦涂。结果表明,蛭弧菌混合体菌液浓度达103PFU/mL时,菌落总数和致病菌的残留率均为0;其浓度大于10 PFU/mL,对操作台等擦涂量大于10 mL/m2时,菌落总数在1 h后残留率不到0.1%,致病菌未检出。

Bdellovibrio mixture, which was mixed of Bdellovibrio nectophore and bdelloplast by 1：1, as a microbial agent was used in the production process of salmon sashimi. The raw materials during rough cleaning were immersed in Bdellovibrio mixture, and the console, processing workshop and tools daubed by bdellovibrio mixture. The results showed that when the concentration of bacteria bdellovibrio mixture was 103 PFU/mL, both the total number of colonies and pathogens residual rate were 0%. When the concentration was greater than 10 PFU/mL and the amount of daub on the console was more than 10 mL/m2, the total number of colonies was less than 0.1% after 1 h, and pathogens were not detected.
