“…Processing methods such as fermentation, germination, roasting, boiling, grilling, steaming, etc, have also been shown to have significant effect on the nutrient density, bulkiness, and viscosity of most traditional complementary foods (Ikujenlola & Fashakin 2005;Anigo et al, 2010). Fermentation is a common way of preserving food, improving digestibility and increasing appetizing flavours (Dewey & Brown, 2003;Igyor et al, 2010).
