Ice cream and related products are generally aerated and characterized as frozen foams. The gas phase volume varies greatly from a maximum of 50% to a minimum of 10-15% (GOFF, 2002). As seen in Figure 2, the overrun was comprised between 35 and 40%. According to Moretti (1979), the incorporation of air in mixtures that contain cocoa solids, which have higher viscosity, is more difficult. In addition, Chang and Hartel (2002) reinforce that other formulation factors such
