various diameters may have a greater role than
simply to deliver lipids to the infant. Thus, the full characterisation
of milk fat globules according to their size will contribute in a better
understanding of their properties and is the first step needed to
relate both the composition and the structural properties of milk
fat globules to their physiological functions.
Milk fat globules are more complex than simple emulsion droplets
because of their biological membrane, called the milk fat globule
membrane (MFGM; thickness: 10–50 nm), the structure and
composition of which depend on the mechanisms of secretion
