以流通、销售中常用的水产品冻藏温度-20℃和-40℃为条件，对新鲜沙蛰进行贮藏试验，并定期对贮藏期内的样品进行指标测定，得到沙蛰冷冻贮藏过程中的品质变化规律。试验测定指标为感官评定、质量变化、水分活度、总挥发性盐基氮（TVB-N）、 TCA可溶性氮、α-氨态氮、三甲胺氮（TMA-N）和菌落总数。试验结果表明，沙蛰在-20℃下最长贮藏时间为150 d，-40℃下贮藏第150天时仍具有较好的品质，且贮藏过程中各项指标与-20℃相比均表现出较大优势。-40℃可作为沙蛰长期贮藏的温度条件，使其维持较优品质，但仍不能很好地解决汁液流失问题。

FreshStomolophusmeleagrisare stored at -20 ℃and -40 ℃. Various indexes are measured during the storage stage to obtain the variation law on the quality ofStomolophusmeleagris. The indexes are sensory index,drip loss,water activity,total volatile basic nitrogen(TVB-N),TCA-soluble nitrogen,amino nitrogen,trimethylamine nitrogen(TMA-N) and total colony count. The research shows thatStomolophusmeleagriscan be preserved for 150 days at -20 ℃,while the quality of samples storing at -40 ℃is superior. All indexes of -40 ℃are better than -20 ℃during the 150 days. Stomolophusmeleagriscan be long-term stored at -40 ℃with good quality. Even so,the increase of drip loss can not be solved.
