Effect of Fermentation on the Proximate Composition of Ripe and Unripe Plantain Flour
Journal Title: Journal of Advances in Microbiology - Year 2017, Vol 2, Issue 3
Abstract
Aim: The aim of the study was to investigate the effect of fermentation when ripe and unripe plantain flour was fermented for 72 hours at room temperature (32°C+2°C). Methodology: The effect of fermentation on the flours was accessed by determining the microbiological quality, proximate composition as well as the anti-nutritional content. Mixed flora of bacteria and fungi were isolated. Different species of fungi (Aspergillus niger, Penicillium spp, Rhizopus spp and Fusarium spp) and bacteria (Staphylococcus aureus, Streptococcus spp, Lactobacillus spp, Leuconostoc spp, Bacillus substilis, Bacillus cereus) were identified. Results: The result of the proximate analysis showed that there was an increase in the crude fibre, protein and carbohydrate contents of both ripe and unripe fermented samples. The contents of protein, crude fibre and carbohydrate of the fermented ripe plantain flour increased from 0.86 +0.03 to 2.91+0.04, from 1.68+0.03 to 2.81+0.11 and from 79.25+0.01 to 85.43+ 0.01 while that of the unripe fermented plantain increased from 1.75+0.03 to 2.86+0.12, from 1.10+0.07 to 1.61+0.05 and from 79.78+0.01 to 88.28+0.08 respectively. Anti-nutrients properties such as tannin, alkaloids, glycosides and flavonoids of the fermented samples decreased. Conclusion: This research work has proven that fermentation increases the nutritional value of food and helps to reduce the anti-nutrient content of food samples that can be hazardous to health.
