乳脂含有大约400种不同的脂肪酸，是所有天然脂肪中最复杂的。乳脂肪酸几乎同样来自两种来源，即饲料和奶牛瘤胃中的微生物活性，牛乳中的脂质主要以水包油乳剂的形式存在于小球中。瑞典牛奶中近70%的脂肪是饱和脂肪，其中约11%是短链脂肪酸，其中近一半是丁酸。牛奶中大约25%的脂肪酸是单不饱和脂肪酸，2.3%是多不饱和脂肪酸，omega-6/omega-3的比例约为2.3。大约2.7%是反式脂肪酸。
Milk fat contains approximately 400 different fatty acid, which make it the most complex of all natural fats. The milk fatty acids are derived almost equally from two sources, the feed and the microbial activity in the rumen of the cow and the lipids in bovine milk are mainly present in globules as an oil-in-water emulsion. Almost 70% of the fat in Swedish milk is saturated of which around 11% comprises short-chain fatty acids, almost half of which is butyric acid. Approximately 25% of the fatty acids in milk are mono-unsaturated and 2.3% are poly-unsaturated with omega-6/omega-3 ratio around 2.3. Approximately 2.7% are trans fatty acids.
