Fatty acid profile, cholesterol content and sensory properties of meat from Podolian young bulls were evaluated. The percentage of saturated fatty acids was higher for LD and lower for SM and ST muscles (P<0.001). Oleic and stearic fatty acids constituted more than 50% of the total fatty acids in all muscles studied. The meat produced by Podolian young bulls showed a favourable percentage content of polyunsaturated fatty acids and a beneficial ratio P/S. Conversely, the ratio n-6/n-3 exceeded the recommended value in the human diet. Changing the time of ageing from 8 to 15 days produced an increment of MDA (P<0.01). The differences in MDA content observed between meat samples aged 8 and 15 days were still detectable after 4 and 8 months of frozen storage. The extension of the ageing period from 8 to 15 days produced an increase in tenderness (P<0.05) and flavour intensity (P<0.01).
研究了波德奥利亚年轻公牛的肉的脂肪酸组成、胆固醇含量和感官特性。饱和脂肪酸的百分比在 LD 中较高,在 SM 和 ST 肌肉中较低(P<0.001)。所有研究肌肉中的油酸和硬脂酸构成了总脂肪酸的 50%以上。波德奥利亚年轻公牛生产的肉具有较高的多不饱和脂肪酸百分比含量和有益的 P/S 比值。相反,n-6/n-3 的比值超过了人类饮食中的推荐值。将老化时间从 8 天延长至 15 天会导致 MDA(丙二醛)含量增加(P<0.01)。在 8 天和 15 天老化的肉样之间观察到的 MDA 含量差异在冷冻储存 4 个月和 8 个月后仍可检测到。将老化时间从 8 天延长至 15 天会增加嫩度(P<0.05)和风味强度(P<0.01)。
