Partial coalescence of the fat emulsion and its control by manipulation of the oilywater interface continues to be an active area
of ice cream research and understanding at both the basic and applied levels have greatly improved. Interactions between all the
discrete phases are increasingly being studied in more complex systems, leading to an appreciation of such things as the effect of
air bubble size distribution on ice recrystallization. The importance of protein polysaccharide phase separation in the freezeconcentrated
unfrozen phase and its effect on ice recrystallization has also been recognised.
