摘要:

测定杜长大三元杂交猪的背最长肌(LDM)、腰大肌(PM)两种不同部位猪肉在宰后0~4℃冷却成熟过程中的钙蛋白酶粗酶液活性、肌原纤维小片化指数和剪切力,对3 个指标的变化进行相关性分析。结果表明:3 个指标均与猪肉宰后成熟时间呈现较高的相关性,而且在猪肉宰后成熟过程中三者之间均呈现较高的相关性,说明钙蛋白酶粗酶液活性和肌原纤维小片化指数与剪切力一样,均可作为评价猪肉嫩度的指标。

Abstract:

The changes in Ca2+-activate-factor (CAF) activity, myofibril fragmentation index (MFI) and shearing force value (SFV) of longissimus dorsi muscle (LDM) and psoas muscle (PM) from Duroc × Landrance × Yorkshire cross breed pigs were studied during storage at 0-4 ℃ for postmortem aging and correlation analysis among the three indexes was conducted. The results showed that all the three indexes had significant correlations with postmortem aging time, and there were significant correlations among the three indexes during postmortem aging, which indicate that both CAF and MFI are two significant indexes of pork tenderness as SFV.

Key words: pork, chilling aging, tenderness indexes, correlation
