摘  要:
以肌肉盐溶性蛋白含量、巯基含量和ATPase活性为生化特性指标,同时结合pH值、感官评定和挥发性盐基氮等指标,考察了美国红鱼在冰藏期间生化特性及鲜度变化情况。结果表明:随着贮藏时间的延长,盐溶性蛋白含量、巯基含量和ATPase活性均呈下降趋势,冰藏12d后分别下降了70.19%、79.44%和64.26%(Ca2+-ATPase活性);冰藏过程中pH值变化不大,但挥发性盐基氮及感官指标变化比较明显,挥发性盐基氮在第9d时达到33.73mg/100g,处于Ⅲ级鲜度范围。

摘  要:
The changes of biochemical properties of Sciaenops ocellatus during frozen storage were studied by measuring the salt-solubility of myofibrillar proteins, SH content, ATPase activities and freshness indexes together with pH value, sensory scores and total volatile basic nitrogen (T-VBN).The results indicated that during 12 days the salt-solubility of myofibrillar proteins, -SH content and the ATPase activities decrease 70.19%, 79.44% and 64.26% (Ca2+-ATPase activities), respectively. During the frozen storage, the pH value dose not change obviously, but the T-VBN value and the sensory scores change remarkably. T-VBN value gets up to 33.73mg/100g after 9 days, being in Ⅲ grade of freshness.
