Notes:
The efficiency of decorticating cowpeas was improved by hydrating to 25%, then drying to ˜10% moisture. Effects of drying temperature (50°, 70°, 90°, 110°, and 130°C) on functional and nutritional properties of cowpea meal were assessed. Extraction rate (yield) was unaffected by heating. Average particle size and water absorption of meal were greatest for intermediate temperatures. Starch was not gelatinized at any temperature. Reduction in protein solubility, which occurred at temperature 〈inlineGraphic alt="geqslant R: gt-or-equal, slanted" extraInfo="nonStandardEntity" href="urn:x-wiley:00221147:JFDS805:ges" location="ges.gif"/〉 90°C., was associated with changes in gel electrophoresis patterns. Protein solubility was negatively correlated with previously reported values for specific gravity and apparent viscosity of cowpea pastes. Increases in drying temperature reduced thiamin content and increased browning of the meal.
