The chemical composition of the total dietary fibers and the heat treated milk bases are shown in Table 1. In general, the chemical composition of apple, banana and passion fruit fibers are in accordance with the results of Nawirska and Kwasniewska (2005), Mohapatra et al. (2010) and Salgado et al. (2010), respectively. As expected, the addition of fiber increased by 1 g/100 g the total solids (total weight − moisture) of the heat treated milk bases.
