RESUMO
Most gluten-free bakery formulations have starch sources of low nutritional value. The objective of this work was to use fava beans (Phaseolus lunatus) for the production of gluten-free sponge cakes, in addition to evaluating the effects of the partial substitution of fava bean flour by galactomannan and xanthan gum, isolated or mixed at 0.5 and 1.0% proportions, compared with a commercial reference. The properties such as viscosity, specific gravity and microscopy of the air bubbles were evaluated in the raw cakes, while the cooked cakes were analyzed according to physicochemical (chemical composition, specific volume, texture and color) and sensorial properties. Hydrocolloids increased the viscosity, specific gravity, and incorporation of air into the batters. Xanthan gum increased the cakes' firmness after cooking; in what concerns color parameters, hydrocolloids did not interfere. Cakes based on fava beans had better sensory acceptance with or without the presence of hydrocolloids and presented higher levels of moisture, proteins, lipids and ashes when compared to the commercial reference, proving to be an excellent food option without gluten and high nutritional value.
