Combined impact of freezing and soaking times on different cowpea varieties' flour functionality and resultant gel strength, sensory and product yield of moi-moi

  • The preparation of moi-moi either from cowpea flour (processed by dry-milling) or paste (processed by wet-milling) has evolved from the indigenous processing methods. Feasibly, freezing should enhance the characteristics of the cowpea grain, and when combined with conventional processing, help to improve emergent products. In this current work, therefore, the combined impact of freezing with soaking times on different cowpea varieties' flour functionality and resultant gel strength, sensory and product yield of moi-moi were studied. Analysis of flour functionality involved the determinations of moisture content, bulk density, oil absorption capacity, swelling index and water absorption capacity, whereas those of moi-moi products involved gel strength, sensory and (product) yield. Across the cowpea flour samples, the functional attributes significantly differed (p < 0.05). Moi-moi products' gel strength of dry-milled appeared higher than wet-milled by specific variety and soaking times. Moi-moi products' sensory attributes of taste, color, texture and general acceptability resembled (p > 0.05), except for the aroma (p < 0.05). Moi-moi products' yield varied widely (p < 0.05) by different reconstituted water volumes. Overall, combining freezing with conventional processing that involved reconstituted water volumes of cowpea promises an enhanced moi-moi yield.
