Germinated and raw finger millet (Eleusine coracana) and pearl millet (Pennisetum glaucum) were investigated for their physicochemical (pH, total titratable acidity (TTA), proximate, mineral analysis), phytochemical, and antioxidant properties. The results showed that there were decreases in pH (8.50–7.60) with a corresponding increase in TTA (0.0038–0.18 g/L) during germination of the millets. Proximate composition of the millets revealed slight increases in protein (7.61%–7.81%; 10.57%–11.87%) and crude fiber (5.54%–8.81%; 1.07%–2.55%) with reductions in fat (3.84%–2.73%; 7.69%–2.30%) after germination for finger and pearl millet, respectively. The millets were found to be rich sources of minerals, which include magnesium (1,028.42–1,763.50 ppm), calcium (36.42–4,158.40 ppm), sodium (150.00–510.00 ppm), potassium (470.00–4,500 ppm), zinc (20.00–40.00 ppm), and iron (66.00–121.00 ppm) which either decreased or increased with germination. The results of the phytochemical composition revealed that during germination, alkaloid (36.03–74.53 mg/g) and saponin (4.46–31.91 mg/g) contents were found to increase while there were reductions in tannin (0.88–1.64 mg/g) and phytate (7.00–17.72 mg/g) content of the flour. For finger millet, DPPH ranged from 70.00% to 72.14% and pearl millet (49.95%–64.01%), while for FRAP, pearl millet (53.69–53.76 mg/g) demonstrated better activity compared to finger millet (46.91–53.54 mg/g). Findings from this work may suggest that further studies should be carried out on germinated finger and pearl millets to examine their abilities to serve as functional foods.
Background The study aimed at evaluating the in-vivo nutritional qualities of extruded breakfast meal produced from flour blends of malted finger millet and watermelon seed. Results The proximate compositions of the flour blends revealed that there was progressive increase in protein (12.83–15.14) %, with increase in the watermelon substitution. The protein quality evaluation of the extrudate showed that the protein efficiency ratio ranged from 0.64 to 89.75, while the biological values were between (87.82–89.75)%. The relative organs weight of rats fed with extruded breakfast meal showed that, the weights of the kidney and liver of rats fed with extruded breakfast meal were significantly lower compared with rats fed with goldenmorn. The hematological indices showed that the packed cell volume and the red blood cell counts of rats fed with the formulated diets were significantly lower compared with those fed with goldenmorn but significantly higher than rats fed with basal. Meanwhile, the values of the white blood cells count for the formulated diet shows no significant difference compared with rats fed with goldenmorn. Conclusions Evidently, the growth performance of the rats fed with the extruded breakfast meal revealed that the formulated diets promote growth status of the animals with relatively low effect on organs of experimental rat used in this study. Hence, formulated diet may serve as alternative to expensive commercial breakfast meal.
This study was carried out to evaluate the qualities of breakfast cereal meals produced from blends of finger millet and toasted African yam beans flour. Flour samples of processed finger millet were blended with roasted African yam beans flour at substitution levels of 0, 10, 20, 30, and 40%. The blended flours were processed into breakfast cereal. The breakfast cereal products were subjected to proximate, vitamin, mineral, and microbial analyses (mould count and total viable count) and sensory evaluation. The result showed that there was a significant increase in the protein, moisture, carbohydrate, and energy content of the breakfast cereals with a corresponding decrease in the ash and fiber content as the level of African yam bean flour increased in the blends. The proximate composition result of the breakfast cereal product ranged from 11.65-37.78% for protein, 13.70-4.91% for ash, 3.00-7.20% for fiber, 2.88-3.88% for moisture, 0.74-1.00% for fat, 46.41-76.77% for carbohydrate and 360.98-380.36% for energy. Vitamin composition of the products ranged from 43.17-72.14 UI for vitamin A, 0.058-0.184 mg/100 g for vitamin B1, 0.058-0.184 mg/100 g for vitamin B2, 0.006-0.015 mg/100 g for vitamin B3 0.289-0.516 mg/100 g. Mineral composition ranged from 6.50-10.01 mg/100 g for iron, 355.53-454.37 mg/100 g for calcium, and 27.65-28.75 mg/100 g for phosphorus content. The total viable count ranged from 2.7 × 102 to 2.8 × 102 cfu/g while the mould was not detected in any of the samples. Results of sensory evaluation showed that FAY60 was the most acceptable breakfast cereal meal.
