Characterization of modified pearl millet (Pennisetum typhoides) starch.
Pearl millet starch (Pennisetum typhoides) was isolated and subjected to hydrothermal, acidic and enzymatic modifications. Native and various modified starches were characterized in terms of yield, moisture, protein, ash, bulk density, swelling power, solubility, colour, sediment volume, gel consistency, water binding capacity, pasting properties, freeze thaw stability and paste clarity. Hydrothermal modification (HTMS) caused an increase in swelling power and solubility. L value was higher for acid and enzymatically modified starches (EMS). A significant reduction (p ≤ 0.05) in sediment volume and water binding capacity was observed for acid modified starch (AMS) and EMS. Peak viscosity values declined for all modifications. However, EMS and AMS showed an improved freeze-thaw stability and paste clarity.
