摘要

摘要分析了人乳、婴儿配方奶和动物乳(牛、山羊、骆驼、驴和牦牛乳)中总脂肪酸(FA)、sn - 2在三酰甘油和磷脂(PL) FA上的位置分布。动物奶的饱和脂肪酸含量(45.08% ~ 66.29%)高于人乳(37.44%)和婴儿配方奶粉(33.46%)。从脂肪酸角度看，人乳与商业配方奶具有较好的相似性。人乳中含有显著的(p <0.05)，比婴儿配方奶粉(23.09%)和动物奶(28.95% ~ 46.72%)高16:0(50.88%)。至于PL‐FA，人乳中含有显著的(p <0.05)比其他牛奶的16:0和18:0高，但比其他牛奶的18:1 n‐9低。人乳中花生四烯酸(AA)、二十二碳六烯酸(DHA)和神经酸(NA)的相对含量在PL‐FA中高于总FA。值得注意的是，人乳中总FA和PL‐FA中AA、DHA和NA的含量都高于其他牛奶。上述结果表明，在sn‐2位置添加16:0，在总FA和总PL‐FA中添加AA、DHA和NA，可以提高婴儿配方奶粉的质量。

Fatty acid concentration and distribution in human milk: Comparison with infant formulas and animal milk

Abstract The lipid profile including total fatty acid (FA), sn ‐2 positional distribution on triacylglycerol, and phospholipid (PL) FA in human milk, infant formulas, and animal milk (cow, goat, camel, donkey, and yak milk) were analyzed. Animal milk contained higher saturated fatty acids (45.08%–66.29%) than human milk (37.44%) and infant formula (33.46%). In the perspective of FA, human milk and the commercial formulas showed a better similarity. Human milk contained significantly ( p < 0.05) higher 16:0 at the sn ‐2 position (50.88%) than infant formulas (23.09%) and animal milk (28.95%–46.72%). As to PL‐FA, human milk contained significantly ( p < 0.05) higher 16:0 and 18:0 but lower 18:1 n‐9 than other milk. The relative contents of arachidonic acid (AA), docosahexaenoic acid (DHA), and nervonic acid (NA) in human milk were higher in PL‐FA than that in total FA. Noteworthy, the contents of AA, DHA, and NA in both total FA and PL‐FA were higher in human milk than other milk. These results indicated that the fortification of 16:0 at the sn ‐2 position, and AA, DHA, and NA in both total FA and PL‐FA could improve the quality of infant formulas.

期刊介绍： The Journal of the American Oil Chemists’ Society (JAOCS) is an international peer-reviewed journal that publishes significant original scientific research and technological advances on fats, oils, oilseed proteins, and related materials through original research articles, invited reviews, short communications, and letters to the editor. We seek to publish reports that will significantly advance scientific understanding through hypothesis driven research, innovations, and important new information pertaining to analysis, properties, processing, products, and applications of these food and industrial resources. Breakthroughs in food science and technology, biotechnology (including genomics, biomechanisms, biocatalysis and bioprocessing), and industrial products and applications are particularly appropriate. JAOCS also considers reports on the lipid composition of new, unique, and traditional sources of lipids that definitively address a research hypothesis and advances scientific understanding. However, the genus and species of the source must be verified by appropriate means of classification. In addition, the GPS location of the harvested materials and seed or vegetative samples should be deposited in an accredited germplasm repository. Compositional data suitable for Original Research Articles must embody replicated estimate of tissue constituents, such as oil, protein, carbohydrate, fatty acid, phospholipid, tocopherol, sterol, and carotenoid compositions. Other components unique to the specific plant or animal source may be reported. Furthermore, lipid composition papers should incorporate elements of yeartoyear, environmental, and/ or cultivar variations through use of appropriate statistical analyses.
