Lipidome changes, with a focus on phospholipids, due to feeding systems and processing in goat milk

Comparative lipidomics analysis of different-sized fat globules in sheep and cow milks

“…4 A), these differences in the TGs and polar lipids between the MFG groups drove the small MFGs to be different from the large MFGs. This is consisted with previous studies on other species that the content of polar lipid was natively correlated to MFG size in goat milk ( Argov-Argaman et al, 2021 ) and cow milks ( Mesilati-Stahy and Argov-Argaman 2014 ). In comparison with sheep milk, cow milk contained significantly ( P < 0.05) lower proportions of LMW TGs in all MFG groups, which is in line with the fatty acid composition result that cow milk contained fewer MCFAs than sheep milk ( Table 1 ).…”

Underlying evidence for the health benefits of fermented foods in humans

“…, not grazing) animals. 135 Some LAB can also metabolise PLs. Pediococcus acidilactici isolated from Gouda cheese contains a PL-hydrolysing phosphoesterase that may enhance the digestibility and intestinal absorption of PLs.…”

“…134 Similarly, higher PL levels were observed in goat milk yoghurt versus goat milk, where the source material was obtained from confined (i.e., not grazing) animals. 135 Some LAB can also metabolise PLs. Pediococcus acidilactici isolated from Gouda cheese contains a PL-hydrolysing phosphoesterase that may enhance the digestibility and intestinal absorption of PLs.…”

Untargeted lipidomics of ovine milk to analyse the influence of different diet regimens

“…Recently, the change of goat lipidome and compositional characteristics of milk from two feeding treatments, grazing vs . hay-feeding in confinement, were reported (Argov-Argaman et al ., 2021). Milk fat and protein contents were higher in grazing goats.…”

“…Except for saturated fatty acids, dietary management affected fatty acid composition, in particular polyunsaturated fatty acids content. Omega 6 and omega 3 fatty acids increased and omega6/omega3 ratio decreased in goat milk under grazing when compared with confined managements (Argov-Argaman et al ., 2021).…”
