SUMMARY:

This study proposes the development of gluten-free sorghum (Sorghum bicolor L. Moench) pasta produced by thermoplastic extrusion, using two genotypes that differ in tannin content (tannin-rich and tannin-free), which have undergone germination and browning. The pasta formulations will be prepared under fixed conditions of moisture and emulsifier content and evaluated for cooking properties (optimal cooking time, water absorption, volume expansion, and loss of soluble solids), instrumental texture, color, phenolic compound content, antioxidant capacity, and in vitro digestibility. The formulations with the best integrated technological, antioxidant, and digestibility performance will be selected for sensory evaluation by a panel of tasters and subjected to microbiological analyses. It is expected that this study will help determine which type of sorghum and pre-processing method results in pasta with the best balance between technological quality and nutritional value, suitable for consumption by the general population and, in particular, as an alternative in the diet of individuals with celiac disease. The results will provide insights for the technological use of sorghum in the production of gluten-free pasta with higher added value, contributing to the expansion of inclusive and healthy foods and to the promotion of crops adapted to Brazilian production conditions.
