Popis: Abstract Flake is consumed in many parts of the world. Flakes are majorly prepared from cereals. However, most flakes are deficient in protein and some other healthful substances. High-protein soymeal is rich in protein, mineral, amino acids, antioxidants, and other healthful substances. Formulating flakes with high-protein soymeal would improve the health status of consumers. This work investigated consumer-ready flake from amaranth, high-protein soymeal, and modified corn starch produced under the optimized condition and characterized with the aim to develop models that would give a healthful consumer-ready flake. Amaranthus viridis, corn, and soybean grains were sorted, wet-cleaned, and dried. Soybean grains were processed into high-protein soymeal, starch was extracted from corn grains while A. viridis grains were processed into flour. Formulated flour mixtures were developed into flakes using three-level factorial categoric factor design of response surface methodology. The flakes were analyzed using standard procedures. Optimal flour mixtures of high-protein soymeal (34.78 g/100 g), amaranth (56.52 g/100 g), and modified corn starch (8.70 g/100 g) were established. Results showed the optimized flakes contained per 100 g: 29.05 g protein, 6.00 g fat, 4.10 g fibre, 3.84 g ash, 8.96 g moisture, 249.74 mg calcium, 272.35 mg magnesium, 12.08 mg iron, 618.42 mg phosphorus, 6.41 mg niacin, 4.85 mg pyridoxine, 0.21 g tannin, 1.85 mg phytate, 2.96 mg alkaloids, 908.24GAE total phenolics and 12.75mgRE flavonoids with good quality characteristics in amino acids. The study illustrated the feasibility of formulating quality consumer-ready flakes from amaranth, high-protein soymeal, and modified corn starch. The production process is scalable and could be employed for both domestic and industrial purposes. Graphical abstract
