Abstract
- Total lipid, total cholesterol, and phospholipid contents per gram of egg yolk were found to be the same for eggs from 21 and 57 week-old hens. 2. In contrast, fatty acid composition of total egg yolk lipid was different for the 2 groups of hens. The contents of long-chain (20 C and 22 C) polyunsaturated fatty acids of n-6 and n-3 series were 20% to 25% higher in egg yolks from the younger hens. 3. This finding is discussed with respect to the nutritional value of eggs from hens of different ages regarding the use of egg yolk lipid in the production of infant formulae.
摘要
- 研究发现，21周龄和57周龄母鸡所产鸡蛋每克蛋黄中的总脂质、总胆固醇和磷脂含量相同。2. 相比之下，两组母鸡所产鸡蛋的蛋黄总脂质脂肪酸组成不同。年轻母鸡所产蛋黄中n-6和n-3系列长链（20碳和22碳）多不饱和脂肪酸的含量高出20%至25%。3. 针对不同年龄母鸡所产鸡蛋在用于生产婴儿配方奶粉时蛋黄脂质的营养价值，对这一发现进行了讨论。
