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.
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).
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. © 2017 Society of Chemical Industry.
无论农场位置或所产肉的来源性别如何,跳羚均被用于肉类生产。本研究调查了农场位置(三个包含不同植被类型的农场)和性别对跳羚胸腰最长肌感官品质的影响。除了测定肉的物理品质、近似成分和脂肪酸组成外,还通过描述性感官分析确定了感官特征(香气、风味和质地)。
农场位置对跳羚肉的感官品质(野味和类似肝脏的香气;牛肉、类似肝脏、类似羊肉和草本的风味;甜味;嫩度;残渣;粉状感;Warner-Bratzler剪切力;水分、蛋白质和肌内脂质含量)和脂肪酸含量(油酸;α-亚麻酸;总饱和脂肪酸和单不饱和脂肪酸;多不饱和脂肪酸与饱和脂肪酸的比例;总ω-3多不饱和脂肪酸;以及ω-6与ω-3多不饱和脂肪酸的比例)有显著影响。性别影响跳羚肉的化学成分;然而,对感官特征的影响较小(甜味;P < 0.001)。
农场位置可能影响跳羚肉的感官品质和成分,在为肉类生产进行屠宰时应予以考虑。在跳羚肉的销售中无需考虑性别。© 2017化学工业协会。
