The biological membrane surrounding milk fat globules (MFGM) exhibits lateral phase separation of lipids, interpreted as gel or liquid-ordered phase sphingomyelin-rich (milk SM) domains dispersed in a fluid continuous lipid phase. The objective of th

The biological membrane surrounding fat globules in milk, the MFGM, is poorly known despite its importance in the functional properties of many dairy products and in the mechanisms of milk lipids digestion occurring in the gastrointestinal tract of m

Increasing knowledge about the composition and biophysical properties of milk lipids is essential to better understand, modulate and control their properties in food products, to developinnovative functional foods but also to tailor specific lipid st

Introduction P. freudenreichii is used both as Swiss-type cheese starters and as probiotics. For these purposes, it should be converted into a powdered form to be stabilized, without significant loss of viability. Freeze-drying and spray drying can b

Sphingomyelin (SM) and cholesterol are major lipid components of biological membranes involved in the formation of ordered domains. In this study, we investigated the biophysical properties of milk-SM bilayers and determined the effect of cholesterol
