摘 要：
为研究时间对不同贮藏温度下速冻羊肉品质的影响,采用了菌落总数、挥发性盐基氮、pH、酸价及水分含量为指标,对速冻羊肉在-15、-20、-25℃三种不同温度冻藏温度和5、15、25℃三种不同冷藏温度下中的上述指标的变化进行了研究。实验结果显示,菌落总数、挥发性盐基氮、pH、酸价随贮藏时间的延长而增加,随贮藏温度的增加而上升。与冷藏温度下贮藏的速冻羊肉相比,冻藏能更好保持速冻羊肉的品质,减缓细菌的生长,减少水分的散失,能更久地保持其品质与延长其货架期。

摘 要：
This experiment mainly aimed at investigating effect of storage temperature on quality of frozen lamb. total bacteria counts(TBC), TVBN, acid value(AV), pH and water content were studied respectively which were taken as testing indices to reflect the quality changing of frozen mutton at -15, -20, -25, 5, 15, 25℃ as the developing of storage time in the experiment. The result indicated that, water content was decreasing with the storage time while the other four indices increased with storage time. Compared to cold storage, frozen storage can keep the quality and prolong the shelf life of frozen lamb.
