The feeding activities of Egyptian geese are becoming a problem for crop farmers in South Africa. Their grain-based diet during the harvesting season compared to the diet during the rest of the year may have an influence on the meat quality, especially the sensory profile. Descriptive sensory analysis, physical measurements, and the proximate composition were used to investigate these effects. Season was a major influential factor with the meat from summer associating with sweet-oily-duck and beef attributes in contrast to the strong association towards the game, metallic, and fish attributes of the winter meat. This is due to the difference in the main fatty acids; winter was higher (P ≤ 0.05) in polyunsaturated fatty acids ( PUFA: ) (C18:3 n-3) and summer higher (P ≤ 0.05) in monounsaturated fatty acid (C18:1 n-9). This study established that season has a significant effect on the sensory profile of Egyptian goose meat and should be considered regarding the utilization and consumption.
埃及雁的觅食活动正成为南非农作物种植者面临的一个问题。与一年中其他时间的饮食相比,它们在收获季节以谷物为主的饮食可能会对肉质产生影响,尤其是感官特征。采用描述性感官分析、物理测量和近似成分分析来研究这些影响。季节是一个主要影响因素,夏季的肉与甜-油-鸭和牛肉的属性相关,而冬季的肉则与野味、金属味和鱼的属性有很强的关联。这是由于主要脂肪酸的差异;冬季的多不饱和脂肪酸(PUFA:C18:3 n-3)含量较高(P≤0.05),夏季的单不饱和脂肪酸(C18:1 n-9)含量较高(P≤0.05)。本研究表明,季节对埃及雁肉的感官特征有显著影响,在利用和消费时应予以考虑。
