Abstract
This work aimed to evaluate the influence in the addition of the Guavira Peel Flour (GPF) on bread regarding the physical-chemical and sensorial characteristics. Three formulations of bread were prepared: standard with 0% GPF (F1); with addition of 0.84% (F2) and 1.96% (F3) of GPF. The elaborate bread with 0.84% guavira peel flour (F2) showed greater acceptability by the tasters, not differing from the standard sample (F1). As for physical-chemical composition, there was a difference between the samples (p < 0.05). Higher levels of ash, carbohydrate and calories and lower moisture and lipid levels were verified for F3. There was no statistical difference (p > 0.05) for the protein contents between the formulations. The incorporation of guavira peel flour resulted in an increase of vitamin C in formulations, however, their amount was not enough to contribute with improvements in the quality of the mass. The incorporation of guavira peel flour was responsible for browning of the breads and indicated tendency towards yellow color in the bark and red color in the crust. The specific volume found in the formulations with guavira peel flour was similar to the standard formulation. In the rheological analysis of the guavira peel flour, there was no difference of tenacity between the samples with the addition of GPF, but the extensibility was higher in the sample with 1.5% of GPF. The flour with 1.5% presented a lower curve configuration index, and the increase of GPF indicated a decrease in the mechanical work. The research demonstrated that the use of this flour was viable in the elaboration of breads with sensorial quality.
