The effect on lamb muscle of five dietary supplements high in polyunsaturated fatty acids (PUFA) was measured. The supplements were linseed oil, fish oil, protected lipid (high in linoleic acid (C18:2 n-6) and α-linolenic acid (C18:3 n-3)), fish oil/marine algae (1:1), and protected lipid/marine algae (1:1). Eicosapentaenoic acid (C20:5 n-3) and docosahexaenoic acid (C22:6 n-3) were found in the highest amounts in the meat from lambs fed diets containing algae. Meat from lambs fed protected lipid had the highest levels of C18:2 n-6 and C18:3 n-3, due to the effectiveness of the protection system. In grilled meat from these animals, volatile compounds derived from n-3 fatty acids were highest in the meat from the lambs fed the fish oil/algae diet, whereas compounds derived from n-6 fatty acids were highest in the meat from the lambs fed the protected lipid diet.
测定了五种富含多不饱和脂肪酸(PUFA)的膳食补充剂对羔羊肌肉的影响。这些补充剂分别是亚麻籽油、鱼油、保护脂质(富含亚油酸(C18:2 n-6)和α-亚麻酸(C18:3 n-3))、鱼油/海藻(1:1)以及保护脂质/海藻(1:1)。在喂食含藻类日粮的羔羊的肉中,二十碳五烯酸(C20:5 n-3)和二十二碳六烯酸(C22:6 n-3)的含量最高。由于保护系统的有效性,喂食保护脂质的羔羊的肉中C18:2 n-6和C18:3 n-3的含量最高。在这些动物的烤肉中,来自n-3脂肪酸的挥发性化合物在喂食鱼油/海藻日粮的羔羊的肉中含量最高,而来自n-6脂肪酸的化合物在喂食保护脂质日粮的羔羊的肉中含量最高。
