摘要:

以Ca2+-ATPase 活性为主要的生化特性指标,同时结合pH 值、挥发性盐基氮(TVB-N)、细菌总数等指标,考察草鱼在4℃冷藏期间与品质和新鲜度相关的各指标的变化情况。结果表明:随着贮藏时间的延长,Ca2+-ATPase活性呈下降趋势,冷藏9d 后活性下降了67.74%;冷藏过程中pH 值、TVB-N 值和细菌总数均呈逐渐上升趋势,pH 值、TVB-N 值和细菌总数存在一定的相关性。

关键词: 草鱼, 冷藏, 新鲜度, 食用品质

Abstract:

Quality change and freshness of grass carp during storage at 4 ℃ were studied by measuring Ca2+-ATPase activity, pH, total volatile basic nitrogen (TVB-N) and total bacteria counts. Results indicated that Ca2+-ATPase activity in grass carp exhibited a declined trend during the storage and 67.74% reduction after storage for 9 days. In contrast, pH, TVB-N and total bacteria counts in grass carp revealed an increase trend during chilled storage.

Key words: grass carp, chilled storage, freshness, edible quality
