摘要:

本实验以兔后腿和背最长肌为材料,研究兔肉宰后成熟过程中理化品质的变化,为兔肉成熟工艺的制定提供理论依据。结果表明:依pH值和色泽指标变化判断,兔肉成熟时间以72 h为宜;依肌原纤维小片化指数(myofibrillar fragmentation index,MFI)和剪切力指标判断,兔肉成熟时间以96 h为宜;依挥发性盐基氮(TVB-N)的变化判断,兔肉成熟时间应≤72 h。从多种因素综合考虑,兔肉的最佳成熟时间为72 h。

关键词: 兔肉, 宰后成熟, 理化品质, 成熟时间

Abstract:

Rabbit rear legs and longissimus dorsi were investigated for changes in physical and chemical qualities during
postmortem aging. The results showed that based on pH and color, the appropriate aging time was 72 h; when myofibrillar
fragmentation index (MFI) and shear value were taken into consideration, the appropriate aging time was 96 h; based on
total volatile basic nitrogen (TVB-N), the aging time was no longer than 72 h. Collectively considered, the best aging time
for rabbit meat was 72 h.

Key words: rabbit meat, postmortem aging, physical and chemical quality, aging time
