Abstract

"French" bread is a highly food consumed by all social classes, however its production from wheat flour is very often questioned. In this way, the use of different flours sources for bread production has been widely explored in the last years. However, in general, it could be observed that researches, and also products developed in market, have "sliced" bread as the focus, while the production of functional French bread remain still little explored. Furthermore, research in this area only characterize the final product, i.e., little information about the creation and development of structure, primarily responsible for texture and other properties of the final product, is available in literature. Thus, the aim of this project is to evaluate the effect of partial replacement of wheat flour by passion fruit peel flour, in the development of crumb and crust structure of French breads during the baking process. Different formulations of French bread, which provide different structures, will be studied in order to better understand how and when the microstructures are created and developed, and their relationship to technological and sensory properties of final product. An in-situ trial will be conducted to characterize not only the final cellular structure, but also to follow the whole process of product development during the baking. The study will be extremely important in the technological area because: (1) it aims to produce foods with functional attributes, (2) involves the appreciation and use of waste in the food industry, which may represent an alternative for country economic independence of imported wheat.
