Abstract

Several bioactive compounds (from fruits, vegetables, grains and cereals) can be applied in the formulation of bread, to improve its nutritional characteristics. Taking this into account and the applications of the freezing technique as a bread dough preservation method, it becomes clear the importance of knowing the behavior of these bioactive compounds in cases where the dough is exposed to a condition of freezing. For this study, we intend to evaluate the fructooligosaccharides (FOS) and inulin present in the yacon (Smallantus sonchifolius), adding yacon flour to the bread dough formulation. In this way, bread produced from frozen dough, pre-baked dough, and fresh dough, with different amounts of yacon flour, would be evaluated, so that it was possible to make a direct comparison between the characteristics of the bread produced. In addition to increasing the nutritional properties of bread, the inulin, depending on the degree of polymerization, can be consumed by the yeast during fermentation, therefore the analysis of total sugars and fructans content will also conduct.
