Instant vegetable cereal was formulated from red amaranth, corn, barley, and pineapple using the drum drier technique. The mixture design using Minitab for optimization of the instant cereal was also studied in terms of antioxidant, mineral, sensory evaluation, nutritional content and microbiology. The most nutritious preferred instant vegetable cereal was determined using the method of radical scavenging activity 2,2-diphenyl-1- picrylhydrazyl (DPPH), zinc, and calcium content. In general, the optimized instant cereals using Minitab software were acceptable to the consumer with nutritional values as high as those of comparable products on the market. The best formulation (Formulation 1) contained a mixture of raw ingredients of 3.10 mg/100 g of zinc, 89 mg/100 g of calcium and 80% of radical scavenging activity (DPPH). The proximate composition showed that formulation 1 contained 77.85 g/100 g of carbohydrate, 7.64 g/100 g of protein, 371 kcal/100 g of energy, 0.36 g/100 g of fat, 12.91 g/100 g of total dietary fibre (TDF), 2.06 g/100 g of ash, and 3.70 g/100 g of moisture. Microbiological analyses showed that total aerobic plate counts, coliform count and yeast and mould count were 2.5×103 CFU/g, < 1.0×10 CFU/g, 1.0×10 CFU/g, respectively. Overall, the best instant vegetable cereal contained vitamin C (110 mg/100 g), vitamin A (4420 µg/100 g), selenium (8.15 µg/100 g), potassium (0.59 g/100 g), calcium (138 mg/100 g) and manganese (2.26 mg/100 g). In conclusion, it can be suggested that the consumption of instant vegetable cereals for daily intake is suitable for maintaining health status. |
