Thermal, Pasting, and Hydration Properties of Flour from Novel Cassava Cultivars for Potential Applications in the Food Industry

Abstract

Cassava root flours from five different cultivars (C-MSAF2, C-P4/10, C-P98/0505, C-P98/0002, and C-UKF8) were studied for their potential application in the food industry. Proximate composition, functional, thermal, and pasting properties were investigated. Cassava flours were high in carbohydrates (85-86%) and their amino acid profiles varied. Cultivars C-MSAF2, C-P98/0002, and C-UKF8 showed high protein content (5.06%), mineral content (2.36%), and the largest particle size (72.33 µm), respectively. Solubility of cassava flours decreased as temperatures increased, however, swelling power and water absorption capacity increased. C-MSAF2 showed the highest peak viscosity, breakdown viscosity, and shortest peak time. C-P98/0505 showed the highest final viscosity, the highest pasting temperature, and the longest peak time. Cassava flours studied are promising candidates for utilization in the baking industry, however, their incorporation into baked product formulations needs further investigation.
