Milk and cream are examples of fat-in-water (or oil-in-water) emulsions. The milk fat exists as small globules or droplets dispersed in the milk serum. Their diameters range from 0.1 to 20 µm (1 µm = 0.001 mm). The average size is 3–4 µm and there are some 10 globules per ml. The emulsion is stabilized by a very thin membrane only 10-20 nm thick (1 nm = 10–9m) which surrounds the globules and has a complicated composition. Milk fat consists of triglycerides (the dominating components), di- and monoglycerides, fatty acids, sterols, carotenoids (giving the yellow colour of the fat) and vitamins (A, D, E, and K). Trace elements are minor components. The composition of a milk fat globule is outlined in Figure 2.16. The membrane consists of phospholipids, lipoproteins, cerebrosides, proteins, nucleic acids, enzymes, trace elements (metals) and bound water. It should be noted that the composition and thickness of the membrane are not constant, because components are constantly being exchanged with the surrounding milk serum. As the fat globules are not only the largest particles in the milk but also the lightest (density at 15.5 °C = 0.93 g/cm they tend to rise to the surface when milk is left to stand in a vessel for a while. The rate of rise follows Stokes’ Law, but the small size of the fat globules makes creaming a slow process. Cream separation can, however, be accelerated by aggregation of fat globules under the influence of a protein called agglutinin. These aggregates rise much faster than individual fat globules. The aggregates are easily broken up by heating or mechanical treatment. Agglutinin is denatured at time-temperature combinations such as 75 °C/2 min and the possibility of aggregation disappears.
