DISCUSSIONโข The plantain flours showed significant difference (p<0.05) for the studied parameters
โข The plantain flours produced from the four varieties of unripe plantain showed high
starch content but low in ash, fat, protein, fibre and sugar content.
โข Plantain flour produced from PITA 27 cultivar had the highest potassium, magnesium,
calcium and low sodium mineral content
โข Plantain flour produced from MBI EGOME cultivar had the highest total carotenoid
content and colour parameters (L*, a*, b* and ฮE)
โข Plantain flour produced from Agbagba (control) cultivar had the highest trough, final
and setback viscosities and lower breakdown viscosity with higher water absorption
capacity, oil absorption capacity, dispersibility and solubility.

CONCLUSION
The results obtained from the study revealed that
the four varieties of unripe plantain flours of good
quality in terms of the parameters studied and can
be kept for longer period because of their low
moisture content.
