Their hydrophilic and lipophilic characteristics allow
them to form bridges between fatty and aqueous phases.
So, we found both in the cream (about 60%) and butter in
skim milk (40%) or buttermilk (Table 8). There are three
main phospholipids: lecithin, Cephalin and Sphingomyelin.
Approximately 85% of fatty acids constituting
phospholipids are long chain fatty acids. Other complex
lipids present in minor amounts are gangliosides,
glycolipids and glycosphingolipids (Florence, 2010).
