【摘要】：为了研究空气和茶多酚结合包装两种不同的包装方式对存在温度变化的冷链物流过程中鲈鱼品质的影响。本实验以鲈鱼为研究对象,通过模拟冷链物流过程4个不同阶段即贮藏(-18℃)、运输(0℃)、销售(2℃)及家用冰箱贮藏(4℃),研究了冷链物流过程中茶多酚结合包装对鲈鱼品质的影响。结果表明,茶多酚结合包装对冷链物流过程中鲈鱼品质的劣化具有明显的缓冲作用,能使鱼肉保持良好的感官品质、到物流末期第20 d时TVB-N值、TBA和菌落总数显著低于对照组,分别为18.11、7.07 mg/kg和5.68 lg CFU/g,保证鲈鱼在物流末期仍处于可食的安全范围。因此,在低温冷链物流尚不完善的情况下,采用茶多酚结合包装能够有效减缓鱼肉品质下降。
[Abstract]:In order to study the air and tea polyphenols combined with two different packaging packaging effect on the quality of cold chain logistics perch in the presence of temperature change. In this experiment, perch as the research object, through simulating the process of cold chain logistics in 4 different stages of storage (-18 C), transportation (0 C), sales (2 c) and refrigerator storage (4 C), the process of cold chain logistics of tea polyphenols combined impact of packaging on the quality of sea bass. The results showed that tea polyphenols combined with the deterioration of the quality of sea bass cold chain logistics in the process of packaging has obvious cushioning effect, can make the fish maintain good sensory quality, to the end of the twentieth D logistics when the value of TVB-N, TBA and the total number of colonies was significantly lower than the control group, respectively 18.11,7.07 mg/kg and 5.68 LG CFU/g, which is still in the safe range of edible perch in the logistics stage. Therefore, in the cold chain logistics is not perfect, the tea Phenol combined packaging can effectively slow down the quality of fish.

【正文快照】： 鲈鱼,又名花鲈、寨花、鲈板等,是重要的经济鱼类之一,同时也是我国高档淡水鱼品种之一[1]。其肉质较嫩,骨刺较少且营养价值丰富,含有丰富的蛋白质、碳水化合物及微量元素,如维生素、烟酸、磷、铁等物质。不仅对肝肾不足的人能够起到较好的补益作用,而且对于胎动不安、产后少乳
