| Popis: | Buttermilk (BM) has recently received much attention as a source of milk fat globule membrane (MFGM) due to its high polar lipid (PL) content, which gives it functional properties and health benefits. Nevertheless BM can be obtained from two different technological processes, i) the BM from the butter oil industry (BM1) and ii) BM from the butter manufacture (BM2). Neutral lipids (NL) and PL characterization from both BM and their MFGM isolated fractions have been qualitatively and quantitatively characterized including the individual phospho- and sphingolipids by HPLC-ELSD as well as triacylglycerols (TAG) and cholesterol and FAME by GC-FID. The results revealed that while BM (either from BM1 or BM2) had a PL fraction of 12–16 %, the MFGM isolated fraction contained about 40 % of PL with major presence of phosphatidylethanolamine (PE), phosphatidylcholine (PC) and sphingomyelin (SM). Besides, MFGM showed a significant increase in the medium molecular weight TAG and cholesterol and almost two fold amount of PUFA content than BM due mainly to linoleic acid. The results of this study provide deeper information on the lipid composition of BM and MFGM isolated fractions of great importance for the design of dietary supplements with potential beneficial effects on human health. This study was supported in part by the Spanish Ministry of Science, Innovation and Universities. Project AGL2017-87884 (MINECO/AEI/FEDER, UE). |
