Bioactive Lipids and phospholipids classes of Buffalo and Goat Milk affected by Seasonal variations
(This article belongs to Vol - 01, Issue - 03)
This research was figuring out the impact of seasonal variations on bioactive lipids content in both Egyptian buffalo and goat milk. Thirty-two samples of buffalo-milk and eighteen goat milk samples were collected and well- mixed to obtain 4 and 3 composite samples respectively. Chemical composition, total conjugated diene (C18:2) & triene (C18:3) and fatty acids profile were estimated using GC-MS apparatus. Phospholipids (PLs) were determined using 31P-NMR technique. Data detected that buffalo and goat milk contained higher contents of Butyric acid (BA) in winter than summer. Results manifested that total Odd and Branched Chain Fatty Acids (OBCFAs) contents of buffalo milk were higher during summer than in winter. Buffalo milk had higher total PLs either in summer or winter seasons than goat milk. Goat milk had higher contents of Phosphatidylcholine (PC), phosphatidylethanolamine (PE), sphingomyelin (SM) and phosphatidylglycerol (PG) but buffalo milk had higher content of phosphatidylserine (PS) and phosphatidylinositol (PI).
