摘要：This research aimed to evaluate the influence of adding cupuassu (Theobroma grandiflorum) and pitaya (Hylocereus polyrhizus) pulps on the physicochemical and sensory properties of milk bread. We prepared four formulations: control (no fruit added), and three formulations where milk was partially replaced for different proportions of pulps. The following percentages were used: cupuassu pulp (32.37 to 41.61%), pitaya pulp (4.62 to 13.87%), and milk (5.60 to 31.52%). The nutritional composition, instrumental color analysis, and acceptability of the bread were assessed. The addition of fruit pulp into the bread reduced up to 41.44% the lipid content, 40.20% of proteins, and 10.27% of caloric value. The colorimetric analysis showed that the increase in pitaya pulp and decrease in cupuassu pulp reduced the lightness (L*) and the coordinate b*, and increased the coordinate a*. The principal components analysis showed that the most accepted bread formulations were those with 18.14% and 20.74% cupuassu pulp, and 7.78% and 5.18% pitaya pulp. Thus, cupuassu and pitaya pulp can be added into bread formulations as alternative to add nutritional value and contribute to the innovation of bakery products.
