Abstract
In this study, the rheological properties of dough prepared from gluten free flours (rice, sorghum, moong, water chestnut and unripe banana) and wheat dough were determined. Pasting properties and viscoelastic properties were analyzed using rheometer and dough rheology experiment was performed on texture analyzer. Water chestnut flour exhibited highest peak viscocity (22.6Pas), trough viscosity (12.1), breakdown viscosity (10.5Pas) and final viscosity (14.92Pas) than others while unripe banana flour showed highest setback viscosity (4.54Pas). Pasting temperature was found to be highest for sorghum followed by wheat and others. The highest elastic (G') and loss (G″) module were obtained for moong flour. Wheat and gluten free flours were found to exhibit thixotropic effect. Moong flour dough was found to be the stickiest (dough stickiness 57.83g) followed by WCF, UBF, wheat, rice and sorghum. Similar trend was observed for dough strength. These flours can be proved as key materials for the gluten-free products market and can provide additional inexpensive advantage to the food processing industry.
