The fatty acid (FA) composition and content of whole milk (3.25% fat) from organic, omega-3 (n-3) FA fortified, and conventional retail brands available in the northeastern U.S. were assessed monthly via gas chromatography. Among the retail labels, organic milk stood out as it contained a distinct and more healthful FA profile, consistently comprising a higher content of unique bioactive FAs (short-chain FAs, odd- and branched-chain FAs, vaccenic acid, and conjugated linoleic acids) per serving, particularly during the warm season. The total content of saturated FAs did not differ by retail label. While organic and n-3 fortified milk contained a similar content of total n-3 FAs, the proportion of individual n-3 FAs differed significantly (organic milk: 18:3 n-3; n-3 fortified milk: 20:6 n-3) as a result of the production system and process, respectively. Overall, per serving, the FA profile of organic milk may provide added nutritional and health benefits.

美国东北部零售牛奶中的脂肪酸含量-对消费者有什么好处？

每月通过美国东北部的有机，omega-3（n-3）强化脂肪酸和传统零售品牌中的脂肪酸（FA）组成和全脂牛奶（3.25％脂肪）含量进行评估。气相色谱法。在零售标签中，有机牛奶脱颖而出，因为它具有独特且更健康的脂肪酸成分，始终包含较高含量的独特生物活性脂肪酸（短链脂肪酸，奇数和支链脂肪酸，牛痘酸和共轭亚油酸）。），尤其是在温暖的季节。饱和脂肪酸的总含量按零售标签无差异。尽管有机奶和n-3强化乳中n-3 FA的含量相似，但各个n-3 FA的比例却存在显着差异（有机奶：18：3 n-3； n-3强化乳：20：6 n -3）分别由于生产系统和过程。总体而言，每份有机牛奶的FA含量可提供更多的营养和健康益处。
