Abstract：
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 (n = 60) and PBMA types (soya, oat, rice, almond, coconut, and hazelnut; n = 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.
摘要：
一些消费者正在用植物性牛奶替代品（PBMA）代替牛奶。本研究旨在表征牛奶(n=60)和PBMA类型(大豆，燕麦,大米,杏仁,椰子,和榛子；每种类型n=10)。在PBMAs和牛奶的脂肪酸（FA）谱中发现了显着差异，特别是在FA多样性（PBMAs中的15个FA与牛奶中的54个FA）和主要FA组的比例方面。椰子的FA谱以饱和FA（SFA）为主，而单不饱和脂肪酸（MUFA）或多不饱和脂肪酸（PUFA）在其余PBMA类型中占主导地位。在任何PBMA类型中均未检测到胆固醇。牛奶FAs的FA谱以SFA为主；然而，不同的SFA个体有不同的健康结果。此外,牛奶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），两者在PBMA中都不存在。
