The objective of this work was to investigate the feasibility of the pell and flesh of the baru, while ingredient in the development of bread-form. From the formulation of a bread standard were developed four types of breads so using to peel and flesh of baru in different proportions (PCB25 - 25.00%, PCB50 - 50.00%, PCB75-75, 00% and PCB100 - 100.00%) to replace the farelo of wheat. The peel and flesh of baru were analyzed for microbiological quality, levels of moisture, protein, lipids, carbohydrates, fiber, ash, pH, content of soluble solids. With the exception of the last two analisys, the others have been held for breads, even to the sensory analysis, specific volume and density. The results were analyzed by the coefficient of variation, analysis of variance, test Tukey (p <0.05) and correlation of Pearson. The analysis of the composition centesimal of the peel and flesh of the baru revealed a high content of carbohydrates (65.00%) and fiber (4.00%), a low concentration of protein and lipid (4.00% and 3.00%, respectively). The peel and flesh of baru presented concentration of soluble solids with a value of 5.00 ° Brix and pH equal to 5.40. The breads have developed an average 34.00% moisture, 2.00% ash, 2.00% of lipids, 13.00% of protein, 42.00% of carbohydrates and 6.00% of total fiber food. There was an increase in up to 58.20% in the content of FAT with increasing proportion of the peel and flesh of the baru. All samples were accepted on the attributes appearance, texture and flavor, and is considered low in total fat, not showing significant difference between them on the content of protein and moisture. The results of microbiological analysis was favorable. The survey showed that the peel and flesh of baru are feasible for implementing technological ingredient in breads, giving improves the nutritional characteristics and sensory attributes.
