Background: Ogi from locally available cereals remains a relatively affordable complementary food in West Africa, but has a tendency to spoil due it high moisture content. This study explored effects of garlic and ginger as biopreservatives in ogi flour. Methods: Ogi flour was prepared from sorghum and quality protein maize grains with different concentrations of garlic and ginger powder (2 and 4% w/w) by fermentation technique. These samples were stored for 16 weeks during which the total titratable acidity, pH, proximate composition, mineral content and total antioxidant activities were determined. Results: The proximate compositions of bio-preserved ogi samples were relatively stable throughout storage. The addition of garlic and ginger slightly increased the ash (0.04%), crude protein and mineral contents (mg/ 100g) of the samples. Magnesium (10.85-13.13 and 5.17-9.72); zinc (1.37-1.78 and 7.01-8.50), manganese (1.30-1.71 and 0.45-0.86) and iron (1.53-1.77 and 0.68-2.77) contents increased on addition (of garlic and ginger) to maize ogi and sorghum ogi flours respectively. The free radical scavenging activity; total phenolic and flavonoid contents increased correspondingly with the antioxidants activity. Conclusion: Although not well known to ogi consumer, the bio-preserved ogi flours showed better nutritional values and have potential as a health food. |
