为了建立牛肉大理石花纹评分的估算方法，为牛肉生产管理提供依据，研究了牛腰肉部分的生物电阻抗特性、核酮糖部分粗脂肪含量和牛肉大理石花纹标准（BMS）值之间的相关性。在一个月的屠宰处理前，对28头日本黑肉牛进行了测量。我们采用四电极法稳健地测量生物电阻抗特性。将针电极插入最后一个腰椎的四个点：100、125、225、250[mm]。使用测量数据计算细胞外电阻雷克斯、细胞内电阻Rin和细胞膜电容Cm。结果表明，Rin与BMS数（r = 0.61，RSME = ± 20.6，P <0.01）和粗脂肪含量（r = 0.71，RSME = ± 19.32，P <0.01）呈显著正相关。研究结果表明，生物电阻抗分析法对牛肉中BMS数量的估计具有潜在的影响，对牛肉生产管理行业具有一定的指导意义。
To establish an estimation method of beef marbling score for beef production management, we have investigated correlations among bioelectrical impedance properties in the sirloin part, the content of crude fat in the ribulose part, and the beef marbling standard (BMS) number. The measurement was conducted with 28 Japanese Black Beef Cattle before one-month slaughter treatment. We adopted the four-electrode method robustly to measure the bioelectrical impedance properties. The needle electrodes inserted into the four points: 100, 125, 225, 250[mm] in a line from the last lumbar vertebra. The extracellular resistance Rex, the intracellular resistance Rin, and the cellular membrane capacitance Cmcalculated using the measured data. As the result, the correlations observed between Rin, the BMS number (r = 0.61,RSME = ±20.6, P <; 0.01) and between Rin, the content of crude fat (r = 0.71,RSME = ±19.32, P <; 0.01). The results revealed that the bioelectrical impedance analysis has potential impact to estimate the BMS number, which would be helpful for beef production management industries.
