During storage of ice cream a number of changes in the
physical structure of the product may potentially occur,
such as disproportionation and coalescence of air cells
(which may alter the overrun value of the product) (Sofjan
and Hartel, 2004) and ice recrystallization, whereby small
ice crystals melt and large crystals grow simultaneously
(Akalın and Erisir, 2008).
