摘要: 本实验对牛宰后骨骼肌肉的生物电阻抗值、pH值、失水率进行了测试,且作出了相应得变化曲线图。结果表明宰后10d牛肉样三项指标均有明显的变化。电阻抗与pH值、电阻抗与失水率、pH值与失水率之间均呈现相关性,相关性在α=0.05水平下显著。

Abstract: The variations and mutual relationships of bio-impedance value, pH value and water loss rate of bovine muscles near freezing point were investigated. The results revealed that bio-impedance value, pH value and water loss rate of bovine muscles change obviously after 10 days of slaughter, and the corresponding trendlines of the three indexs were plotted; Correlativities between bio-impedance value and value pH, value pH and water loss rate, water loss rate and bio-impedance are significant (α =0.05).
