A factorial design was used to study the effect of dietary fish oil (1.25% and 2.5%), all-rac-alpha-tocopheryl acetate (70 and 140 mg/kg), and Zn supplementation (0 and 200 mg/kg) on the composition and consumer acceptability of chicken meat stored at -20 degrees C for 5 mo. Supplementation of the diet with all-rac-alpha-tocopheryl acetate increased the alpha-tocopherol content in meat. The fatty acid composition of the meat was affected only by the amount of fish oil. Diets supplied with 2.5% fish oil produced meat with an eicosapentaenoic and docosahexaenoic acid content double that of diets supplied with 1.25% fish oil. Zn supplementation did not affect the content of this mineral in the meat. Moreover, the consumer acceptability of meat samples showed no significant differences between dietary treatments after 5 mo of storage at -20 degrees C or with respect to a freshly cooked commercial sample used as a blind control.
采用析因设计研究了日粮中鱼油（1.25%和2.5%）、消旋α-生育酚醋酸酯（70和140 mg/kg）以及锌补充剂（0和200 mg/kg）对在-20℃储存5个月的鸡肉组成和消费者可接受性的影响。在日粮中添加消旋α-生育酚醋酸酯可提高肉中α-生育酚含量。肉的脂肪酸组成仅受鱼油添加量的影响。添加2.5%鱼油的日粮所产肉中的二十碳五烯酸和二十二碳六烯酸含量是添加1.25%鱼油日粮所产肉的两倍。补充锌对肉中该矿物质的含量没有影响。此外，在-20℃储存5个月后，不同日粮处理的肉样在消费者可接受性方面与用作盲法对照的新鲜烹制商业样品相比，没有显著差异。
