The relationship between chemical compositions, meat quality traits, and palatability attributes in 10 primal cuts from Hanwoo steer carcasses were assessed. Sensory palatability attributes of Hanwoo beef were more closely related with fat content than to moisture or protein content. Among the chemical compositions, only fat had a significant correlation with juiciness (0.67, p<0.001), tenderness (0.32, p<0.05), and overall palatability (0.56, p<0.001). Oleic acid (%) was not significantly related with overall palatability (p>0.05). Overall palatability was negatively correlated with drip loss (-0.32, p<0.05), cooking loss (-0.36, p<0.05), and shear force (-0.54, p<0.01). The correlation between fat content and overall palatability was increased when higher fat cuts (Ansim, Dungsim, Chaekeut, Yangjee, and Kalbi) were analyzed, compared to lower fat cuts (Moksim, Abdari, Udun, Suldo, and Satae). Also, the correlation between shear force and overall palatability was decreased in lower fat cuts compared to higher fat cuts. Our results suggest that the palatability of Hanwoo beef can be improved by increasing fat content in muscles, as increased fat content leads to an increase in sensory tenderness, flavor, and juiciness.
评估了韩牛阉牛胴体10个主要切块的化学成分、肉质性状和适口性属性之间的关系。韩牛肉的感官适口性属性与脂肪含量的关系比与水分或蛋白质含量的关系更密切。在化学成分中,只有脂肪与多汁性(0.67,p<0.001)、嫩度(0.32,p<0.05)和总体适口性(0.56,p<0.001)有显著相关性。油酸(%)与总体适口性无显著相关性(p>0.05)。总体适口性与滴水损失(-0.32,p<0.05)、烹饪损失(-0.36,p<0.05)和剪切力(-0.54,p<0.01)呈负相关。与低脂肪切块(목심、Abdari、Udun、Suldo和Satae)相比,分析高脂肪切块(안심、둥심、책귀、양지和갈비)时,脂肪含量与总体适口性之间的相关性增加。此外,与高脂肪切块相比,低脂肪切块中剪切力与总体适口性之间的相关性降低。我们的结果表明,通过增加肌肉中的脂肪含量可以提高韩牛肉的适口性,因为脂肪含量增加会导致感官嫩度、风味和多汁性增加。
