Abstract This research explores the development and evaluation of breakfast cereals formulated from pearl millet (P-1) and finger millet (F-1) flours, with a focus on their nutritional composition and potential anti-obesity properties. The techno-functional properties were assessed, revealing that P-1 exhibited a bulk density of 0.40 ± 0.01 g/ml and a true density of 0.61 ± 0.03 g/ml, while F-1 showed a bulk density of 0.54 ± 0.03 g/ml and a true density of 0.65 ± 0.02 g/ml. The Carr index and Hausner ratio were significantly higher in P-1 (40.33 ± 0.41 and 1.68 ± 0.03, respectively) compared to F-1 (22.3 ± 0.3 and 1.31 ± 0.02, respectively). Both flours demonstrated comparable water absorption indices, but P-1 had superior foaming capacity and stability. Nutritional analysis indicated that P-1 contained 12.64% moisture, 6.02% fat, 10.29% protein, 63.94% carbohydrates, 2.38% ash, and 2.75% fibre, whereas F-1 had 8.92% moisture, 1.78% fat, 8.65% protein, 73.65% carbohydrates, 1.77% ash, and 4.04% fibre. Composite flours (PF-1, PF-2, PF-3) exhibited varying compositions: PF-1 had 9.86% moisture, 5.83% fat, 11.62% protein, 66.04% carbohydrates, 2.19% ash, and 3.03% fibre; PF-2 had 10.79% moisture, 3.87% fat, 10.01% protein, 68.97% carbohydrates, 2.05% ash, and 3.37% fibre; PF-3 had 9.87% moisture, 2.84% fat, 9.33% protein, 71.12% carbohydrates, 1.92% ash, and 3.74% Fiber. Antioxidant activity was higher in F-1 (80.63%) compared to P-1 (59.58%), with PF-1, PF-2, and PF-3 showing 64.84%, 70.14%, and 75.4%, respectively. Lipase and amylase inhibition capacities were 73.15% and 28.66% for P-1, 28.31% and 30.65% for F-1, and varied for composites: PF-1 (79.12% lipase, 46.41% amylase), PF-2 (50.75% lipase, 53.15% amylase), and PF-3 (39.51% lipase, 41.84% amylase). These findings underscore the distinct nutritional and functional properties of these flours, highlighting their potential in obesity management.
