摘要： Lipids are very important for human health and milk is a rich dietary source of lipids. In this study, the lipid content in three types of milk (goat, soy and bovine) were determined by using UPLC-Q-Exactive Orbitrap Mass Spectrometry. A total of 13 classes of lipids (including Cer, SM, LPC, PC, PE, DG, TG, PA, PG, PI, PS, LPE, FA) were measured. Moreover, lipid profiles differed significantly between the different milk types. Soymilk is rich in phospholipids including PC, PE, PS, PG, while goat milk is rich in medium chain triglycerides (MCT), USFA, omega-6 FA and omega-3 FA, especially EPA and DHA. Furthermore, a PLS model was established for differentiation of milk types based on the lipid profiles. A total of 14 lipids were identified as biomarkers for differentiation of milk types, thus providing a basis for milk authentication and detection of adulteration. (C) 2016 Elsevier Ltd.
