An exploratory study on the quality of the Longissimus thoracis et lumborum muscle of impala (Aepyceros melampus), mountain reedbuck (Redunca fulvorufula) and springbok (Antidorcas marsupialis) in South Africa

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) pH₂₄ 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.
