中文摘要：以细菌总数和大肠菌群为指标,探讨了臭氧对近江牡蛎的净化效果;并分析了臭氧净化处理对牡蛎存活率的影响以及净化前后牡蛎的主要营养成分变化。在净化温度20℃条件下,探讨了循环海水流量、贝水比对净化工艺的影响,得出最佳的近江牡蛎净化条件,并对该条件下净化前后牡蛎的存活率、主要营养成分进行了分析。实验结果表明:利用臭氧制备无菌海水(臭氧浓度0.15mg/L),在温度20℃、净化海水流量1.68t/h.m3、贝水比1:10的条件下净化24h,细菌总数和大肠菌群指标符合海水贝类卫生标准(GB2744-1996)。在净化过程中牡蛎的存活率达到100%,主要营养成分无显著变化。

外文摘要：Taking the total count of bacteria colonies and coil forms level as the parameter index, the effect of Crassostrea Rivularis depuration using ozone were studied.The survival rate and the variation of the main nutritional components of Crassostrea Rivularis during depuration using ozone were also investigated.The ratio of shellfish to seawater and seawater current capacity influencing the depuration effect of Crassostrea Rivularis were discussed at 20℃, and the optimal depuration was obtained. The survival rate and the variation of the main nutritional components of Crassostrea Rivularis under that condition were analyzed. The result suggested that prepared aseptic seawater by using ozone（concentration of ozone was 0.tSmg/L） under the conditions that the temperature was 20℃; seawater current capacity was 1.68t/h · m3; the ratio of shellfish to seawater was 1：10; and the depuration time was 24h,the total count of bacteria colonies and coil forms level accorded with hygiene standards of marine shellfishes（GB2744-1996） after depuration.During depuration,the survival rate reached 100%, and the main nutritional components of Crassostrea Rivularis showed no significant change.
