Abstract
BACKGROUND: Springbok are harvested for meat production irrespective of farm location or sex from which the meat is derived. The present study investigated the influence of farm location (three farms containing different vegetation types) and sex on the sensory quality of springbok longissimus thoracis et lumborum muscle. The sensory profile (aroma, flavour and texture) was determined by descriptive sensory analysis, in addition to determination of the physical meat quality, proximate and fatty acid composition. RESULTS: Farm location had a significant influence on the sensory quality (gamey and liver-like aroma; beef, liver-like, lamb-like and herbaceous flavour; sweet taste; tenderness; residue; mealiness; Warner-Bratzler shear force; moisture, protein and intramuscular lipid content) and fatty acid content (oleic acid; α-linolenic acid; total saturated and monounsaturated fatty acids; polyunsaturated to saturated fatty acid ratio; total omega-3 polyunsaturated fatty acid; and omega-6 to omega-3 polyunsaturated fatty acid ratio) of springbok meat. Sex influenced the chemical composition of springbok meat; however, the influence on the sensory profile was minor (sweet taste; P < 0.001). CONCLUSION: Farm location could influence the sensory quality and composition of springbok meat and should be considered when harvesting for meat production. Sex does not have to be considered for the marketing of springbok meat.
