ABSTRACT The aim of this work was to improve sweet bread (R1) nutritionally by partially replacing the wheat flour with other non-traditional flours through linear programming. Chemical Score, lipid profile, microbiological quality and acceptability were determined. Both recipes, R2 and R3, were formulated according to the Dietary Guidelines for Americans; and R3 according to the maximum amounts of flours that impart negative sensory attributes, as well. The resulting proportions were: wheat/broad bean/chia/ amaranth flours 64/22/13/0 (R2) and 83/2/4/11 (R3). The obtained products presented adequate contributions of proteins and lipids, while fiber increased significantly. The Chemical Score increased from 46% (R1) to 95% (R2) and to 91% (R3) respectively, and the fatty acids ratio ω3: ω6 improved. R2 was not sensorially accepted while R3 presented high acceptability in adults and school-aged children. Recipe R3 could be included in school menus to improve children's nutritional status.
