Chemical analysis revealed that germinated mixture flour crackers (GMFCs) were higher in ash (2.14–2.40%), fiber (1.26–1.75%), protein (5.59–8.31%), and energy (379.64–404.77 kcal/100g) but lower in carbohydrates (70.51–61.05%).

Maize crackers exhibited higher color characteristics (L*, a*, and b*) compared to the other GMFCs. Mean sensory evaluation indicated that the GMFCs were generally accepted by panelists. Overall acceptability and taste of crackers in Formula F4 were preferred by the panelists, particularly with the increased ratio of millet flour. This study demonstrated the potential of composite flours from GMFCs to produce acceptable, healthy, and nutritious crackers.
