中文摘要：

研究了经过0.2%茶多酚浸泡的大黄鱼片和对照组在0℃冷藏条件下20 d内品质变化特性。定期分析了处理组和对照组大黄鱼片样品的微生物指标（菌落总数）和理化指标（pH、MDA、K、MetMb、Mb、Caspase-3）。结果表明,冷藏过程中茶多酚处理能够降低化学指标活性,抑制微生物的生长,保持和延长鱼片保质期。因此,在0℃真空包装冷藏保鲜过程中茶多酚处理能更长时间保持大黄鱼片的良好品质。

英文摘要：

The effect of tea polyphenols（TP,0.2%,W/V） on the fillet quality of large yellow croaker（Pseudosciaena crocea） were evaluated over a 20 day storage under refrigerated temperature（0℃）.The control and the treated fillet samples were analysed periodically for physicochemical（pH,MDA,K value,percentage of metmyoglobin,myoglobin value,Caspase 3 activity） and microbiological（total viable counts） indexes.Dipping treatments predominantly decreased chemical changes,inhibited bacterial growth and prolonged the quality of samples,compared to control fillets.The results indicated that the effect of the TP treatments on the fillet samples were to enable the good quality characteristics to be retained for longer time under the cold storage（0℃）.
