Some consumers are replacing cow's milk with plant-based milk alternatives (PBMAs). The present study aimed to characterize the lipid profiles of cow's milk ( = 60) and PBMA types (soya, oat, rice, almond, coconut, and hazelnut; = 10 per type). Significant differences were found in the fatty acid (FA) profiles of PBMAs and milk, particularly in FA diversity (15 FAs in PBMAs vs 54 FAs in milk) and the proportion of prime FA groups. The FA profile of coconut was dominated by saturated FAs (SFA), whereas monounsaturated FAs (MUFA) or polyunsaturated FAs (PUFA) were dominant in the remaining PBMA types. Cholesterol was not detected in any PBMA type. The FA profile of milk FAs was dominated by SFA; however, different individual SFA have varying health outcomes. Additionally, milk contains some FA groups with health-promoting properties, such as methyl-branched-chain FAs (BCFA) and conjugated linoleic acid (CLA), both of which are absent in PBMAs.
一些消费者正在用植物性奶替代品（PBMAs）替代牛奶。本研究旨在描述牛奶（n=60）和 PBMAs 类型（大豆、燕麦、大米、杏仁、椰子和榛子；n=每种类型 10）的脂质特征。在 PBMAs 和牛奶的脂肪酸（FA）分布中发现了显著差异，特别是在 FA 多样性（PBMAs 中有 15 种 FA，而牛奶中有 54 种 FA）和主要 FA 组的比例方面。椰子的 FA 分布以饱和脂肪酸（SFA）为主，而其余 PBMAs 类型则以单不饱和脂肪酸（MUFA）或多不饱和脂肪酸（PUFA）为主。在任何 PBMAs 类型中都未检测到胆固醇。牛奶 FA 的 FA 分布以 SFA 为主；然而，不同的 SFA 对健康的影响也不同。此外，牛奶还含有一些具有促进健康特性的 FA 组，如甲基支链脂肪酸（BCFA）和共轭亚油酸（CLA），而这些在 PBMAs 中都不存在。
