Abstract

Studied were conducted to evaluate the combined effects of spontaneous fermentation and Amylase Rich Flours (ARF) on some nutritive value, functional and viscoelastic properties of cowpea-fortified nixtamalized maize. A 2x3x3 factorial design, with fermentation medium, fermentation time and ARF level was performed. The blends were fermented for the specific times and analysed for their titratable acidity, pH, water absorption capacity, viscoelastic properties, texture, protein and mineral content. Fermentation and ARF addition influenced titratable acidity, pH, water absorption, viscoelastic properties and texture of the cowpea-fortified nixtamalized maize. Addition of ARF decreased the viscoelastic properties, texture and pH of all the blends with corresponding increase in acidity. Slight increases in protein and ash content were noted with products fermented in coconut water, but ARF addition had only marginal effect. Thus, fermentation and ARF addition could be applied to cowpea-fortified nixtamalized maize to enhance the functionalities with reduced viscosity and texture suitable for weaning food formulations.
