摘要:
为了探讨三甲胺+二甲胺与氧化三甲胺摩尔比值[(TMA+DMA)/TMAO]指标评价鱼产品在-18 ℃条件下腐败进程的可能性,应用比色法测定冷冻4种鱼类(鲈鱼、草鱼、大菱鲆、罗非鱼)贮藏过程中的(TMA+DMA)/TMAO摩尔比值变化,用以判断鱼片的腐败进程。结果显示:TMA含量、DMA含量、甲醛(FA)含量、TMAO含量和菌落总数(TVC)不能对这4种鱼做出准确的新鲜度评价;在-18 ℃条件下,(TMA+DMA)/TMAO摩尔比值呈稳定的上升趋势,并且同一贮藏温度下的(TMA+DMA)/TMAO摩尔比值与挥发性盐基氮(TVB-N)含量存在极显著相关性。表明(TMA+DMA)/TMAO摩尔比值可以作为判定冷冻条件下鲈鱼、大菱鲆、草鱼和罗非鱼新鲜度的指标。
Abstract:
The possibility of evaluating the spoilage progress of fish at -18 ℃ using N-oxide molar ratio of trimethylamine+dimethylamine and trimethylamine-oxide [(TMA+DMA)/TMAO] was studied by employing calorimetric method to detect (TMA +DMA)/TMAO molar ratios of four kinds of fish during frozen storage. The contents of TMA, DMA, formaldehyde (FA), TMAO and total bacterial count (TVC) of the four fish were not able to make an accurate evaluation of the freshness. At -18 ℃, (TMA+DMA)/TMAO molar ratios showed a steady increasing trend over time and was significantly correlated with TVB-N content. The results indicated that the molar ratio of (TMA+DMA) /TMAO was applicable for detection of the freshness of frozen perch, turbot, grass carp and tilapia.
