鉴于某些婴儿对母乳潜在的食物过敏，对从母乳库获得的七个母乳样本和四个婴儿配方奶粉的脂质谱进行了比较。人类样本中的胆固醇 (0.15-0.26 mM) 含量比婴儿配方奶粉中的胆固醇含量低约 50%，而这些产品的甘油三酯 (TG，173-386 mM) 含量则相当。主要饱和脂肪酸(SFA)和单不饱和脂肪酸(MUFA)分别为16:0和18:1。主要多不饱和脂肪酸 (PUFA) 与 C18、C20 和 C22 家族的其他 PUFA 成员的比例为 18:2，并进行了鉴定和定量。尽管在所有测试的婴儿配方奶粉中均未检测到共轭亚油酸 (CLA)，但未发现脂肪酸模式的其他重大差异。然而，母乳样品中 n-6 PUFA/n-3 PUFA 比率的平均值 (13.6) 比婴儿配方奶粉样品中观察到的值高约 50%。尽管我们的结果表明，胆固醇和 CLA 含量以及 n-6 PUFA/n-3PUFA 的比例存在微小但显着的差异，但奶库母乳和婴儿配方奶粉的脂质成分相当相似。
Lipid profiles of seven human breast milk samples obtained from milk banks and four infant formulas were compared in view of the potential food hypersensitivities of certain infants to human milk. The cholesterol (0.15-0.26 mM) content of the human samples was about 50% lower than that found in the infant formulas whereas the triglyceride (TG, 173-386 mM) contents of these products were found to be comparable. The major saturated fatty acid (SFA) and mono-unsaturated fatty acid (MUFA) were 16:0 and 18:1 respectively. The major poly-unsaturated fatty acid (PUFA) was 18:2 with other PUFA members of the C18, C20 and C22 families identified and quantified. Although conjugated linoleic acid (CLA) was not detected in any infant formulas tested, no other major differences in the fatty acid patterns were found. However, the mean (13.6) of the ratio of n-6 PUFAs/n-3 PUFAs in the human milk samples was about 50% higher than that observed in the infant formula samples. Although our results indicate that there are small yet significant differences in cholesterol and CLA content and the ratio of n-6 PUFAs/n-3PUFAs, the lipid composition of milk bank breast milk and infant formulas is quite comparable.
