Article 5: Improving the nutritional quality of ben-saalga, a traditional fermented milletbased gruel, by co-fermenting millet with groundnut and modifying the processing method. Figure 1. Description of the two processing methods (the traditional one and the modified one) experimented on blends of pearl millet and groundnut to produce enriched fermented gruels. Figure 2. Changes in pH (A) ( : Millet-groundnut and : millet) and concentrations of sugar (B) ( :Glucose, :Fructose, :Melibiose and : Maltose), ethanol, lactate and acetate (C) ( : Lactate, : Ethanol and : Acetate) in the soaking of milletgroundnut blend. Bars indicate standard deviation. Figure 3. Changes in pH during the fermentation step in MG-T and MG-CMI processing methods ( : MG-T and : MG-CMI). Bars indicate standard deviation. Figure 4. Changes in sugar concentrations ( :Glucose, :Fructose, :Melibiose and : Maltose) in MG-T (A) and MG-CMI (B), and in ethanol, lactate and acetate concentrations ( :Lactate, :Ethanol and :Acetate) in MG-T (C) and MG-CMI (D) in supernatant of pastes during the fermentation step. Bars indicate standard deviation.
