Storage Stability and Shelf Life Prediction of Food Formulations from Malted and Fermented Maize (Zea mays l.) Fortified with Defatted Sesame (Sesamun indicum l.) Flour

Objective: The effect of malting and fermentation on the storage stability and shelf life of maize/sesame food formulations was investigated. Subjects/ Materials and Methods: Various composite flours of malted and fermented maize and defatted sesame were produced by material balancing, to give four food formulations, consisting of unmalted maize + defatted sesame flour (UMS), malted maize + defatted sesame (MMS), unmalted, fermented maize + defatted sesame flour (UFMS) and malted fermented maize + defatted sesame flour (MFMS), all containing 16g protein and 9g fat / 100g food. The storage stability and shelf life of the food formulations were then determined using standard procedures. Results: While the viscosity of the food formulations significantly (
