Physicochemical quality, fatty acids, volatile compounds and shelf-life profiles of the longissimus thoracis et lumborum muscle of three game species: impala, mountain reedbuck and springbok harvested from a private game estate were measured. Average live weight at slaughter that ranged from 28 to 36 kg was included in the study. The carcass weights were recorded 24 h after slaughter. The longissimus thoracis et lumborum (LTL) muscle was sampled for meat analyses. Impala and springbok LTL had higher (P ≤ 0.05) pH and cooking loss values than the mountain reedbuck. In addition, the springbok had more tender (P ≤ 0.05) meat than the impala and mountain reedbuck. The mountain reedbuck and springbok had higher (P ≤ 0.05) proportions of oleic acid, total monounsaturated fatty acids (FA), linoleic acid, omega (n)-6 polyunsaturated FA, and alpha-linolenic acid compared to impala. During retail display, redness and chroma decreased over time, while yellowness and hue showed an upward trend for all species (P ≤ 0.05). It was observed that species affected meat quality, total proportions of fatty acids and volatile compounds.
对来自私人狩猎场的三种猎物(大羚羊、马羚和跳羚)的背最长肌的理化特性、脂肪酸、挥发性化合物和货架期进行了研究。该研究纳入了宰前平均活重为 28-36kg 的动物。宰后 24 小时记录胴体重。对背最长肌进行了肉质分析。大羚羊和跳羚的背最长肌 pH 值和蒸煮损失值均高于马羚(P≤0.05)。此外,与大羚羊和马羚相比,跳羚的肉质更嫩(P≤0.05)。与大羚羊相比,马羚和跳羚的油酸、总单不饱和脂肪酸(MUFA)、亚油酸、ω(n)-6 多不饱和脂肪酸和α-亚麻酸比例更高(P≤0.05)。在零售展示过程中,所有物种的红色值和色差值随时间的推移而降低,而黄度和色调呈上升趋势(P≤0.05)。研究发现,物种影响了肉质、脂肪酸和挥发性化合物的总比例。
