The ice cream flavor and color is normally generated through adding a small
amount (i.e. approximately 0.3% ice cream mix) of liquid flavors and
colors after aging and before freezing (Schmidt, 2004). Homogenization
can reduce the particle size and aggregation of fat globules at low
temperature, compensate the function of stabilizer, enhance ice cream
viscosity but elevate the oxidation of milk fat and instability of
proteins (Bodyfelt, Tobias, & Trout, 1988; Goff, 1999; Spreer, 1998;
Sweetsur & Muir, 1983).
