Abstract

Recent years have had an increased demand for goat milk and its products. The quality of goat milk is determined, in part, by the fatty acid (FA) profile, but there is little information about breed influence on the FA profile of goat milk. The aim of this study was to describe and compare FA profiles of goat milk produced by Saanen and Swedish Landrace breeds. FA profiles were analysed by gas chromatography with a flame ionisation detector using 100 m capillary column coated with ionic liquids of extreme polarity (SLB-IL111). The amounts of 19 FAs were measured. Analyses indicated that FA profile in the milk of Saanen goats differs from that of Swedish Landrace goats with the first having higher proportions of most SFA-s and the second having lower proportions of C16:0, C16:1 and C18:1. This knowledge enables the improvement of the quality of goat milk and goat milk-derived products.

摘要

近年来，人们对山羊奶及其产品的需求不断增加。山羊奶的质量部分取决于脂肪酸（FA）谱，但关于品种对山羊奶 FA 谱影响的信息很少。本研究的目的是描述和比较萨能奶山羊和瑞典兰德瑞斯奶山羊产奶的 FA 谱。使用带有极端极性离子液体（SLB-IL111）的 100m 毛细管柱通过气相色谱法和火焰离子化检测器分析 FA 谱。测量了 19 种 FA 的含量。分析表明，萨能奶山羊乳的 FA 谱与瑞典兰德瑞斯奶山羊乳的 FA 谱不同，前者含有更高比例的大多数 SFA，后者含有更低比例的 C16:0、C16:1 和 C18:1。这一知识可以提高山羊奶和山羊奶衍生产品的质量。
