The presence of trans octadecenoic acid isomers was detected and analyzed in 24 hr pooled samples of human milk. Amounts of the trans isomers of the C18 monoenes ranged from 2% to 4% of the total fatty acids. For purposes of comparison, three commonly used brands of infant formula were also analyzed and found to contain 0.1% to 1.3% of trans monoene isomers. Data indicate that breast-fed and bottle-fed infants are receiving minimal levels of trans fatty acids via milk.
在人乳的24小时混合样本中检测并分析了反式十八碳烯酸异构体。C18单烯反式异构体的含量占总脂肪酸的2%至4%。为作比较，还分析了三种常用品牌的婴儿配方奶粉，发现其反式单烯异构体含量为0.1%至1.3%。数据表明，母乳喂养和奶瓶喂养的婴儿通过乳汁摄入的反式脂肪酸水平极低。
