Abstract

Despite the growth of the gluten-free food market in recent years, there is still limited access to these products due to the high prices, limited variety and availability and poor sensory properties. However, besides the poor technological and sensory quality, gluten-free breads (GFB) often present poor nutritional composition because they are made from refined flours and starches. Therefore, enhancing the nutritional quality of GFB is an important task for research and development, which is a concomitant challenge towards the improvement of technological and sensory properties. Pseudocereals are gluten-free raw materials, rich in nutrients and bioactive compounds. Thus, the objective of this work is to define the ideal proportions of whole pseudocereals flour to enable the preparation of GFB with good physical properties, composition and acceptability. Mixture design and response surface methodology will be used to define the ideal proportion of each pseudocereal flour (amaranth - AF, quinoa - QF and buckwheat - BF) that can be incorporated into the rice flour e - RF and potato starch - PS mixture, enabling simultaneous optimization of the expansion, crumb softness and moisture, as well as GFB acceptability. Thereby, three mixture experimental designs will be conducted: (1) AF, RF, PS; (2) QF, RF, PS and (3) BF, RF, PS. For each mixture design, twelve experimental formulations will be prepared. The optimal formulations will be evaluated for chemical composition and shelf life in comparison a control GFB formulation and bread made with wheat flour. It is expected an innovative contribution to gluten-free baking technology.
