摘　　要：以等离子体活化冰与自来水冰室温下(20℃)贮藏对虾,对比二者pH、TBA、TVB-N、菌落总数、细菌群落、质构和色差等指标的变化。结果表明:试验期间,等离子体活化冰处理对虾的TBA和pH值增长速率减缓,TVBN值的升高速度远小于自来水冰组,且等离子体活化冰处理虾的硬度下降幅度也小于自来水冰处理的;等离子体活化冰能够明显抑制对虾中细菌的生长,贮藏第6天时,自来水冰处理虾中菌落总数比等离子体活化冰处理的高2lg CFU/g;二代高通量测序结果表明,等离子体活化水主要对弧菌具有抑制效果,贮藏6d时对照组弧菌属占比62.52%,而试验组仅为40.45%。To verify the effect of plasma-activated water(PAW)ice on shrimps(Penaeus Orientalis)preservation,we stored shrimps with PAW ice and tap water(TW)ice at 20℃and compared their differences in pH,TBA,TVB-N,total number of colonies,bacteria diversity,texture and color.The results showed that during 0~6 days storage period,the TBA and pH growth rate of the shrimps treated by PAW ice decreased,and the TVB-N value increased much faster than the TW ice-treated group.Moreover,the hardness of the shrimps treated with PAW ice was also less than that of TW ice-treated.This work also showed that PAW ice could significantly retard the bacterial growth in shrimps.On the 6 th day,the total number of colonies in TW ice-treated shrimps was 2 lg CFU/g higher than that in PAW ice group.In addition,the results from high-throughput sequencing revealed that PAW could inhibit Vibrio.On the 6 th day of preservation,the proportion of vibrio in the control was62.52%,while it was only 40.45%in the treated group.
