The influence of fermentation on proximate composition, antioxidant capacity and functional properties of okra seeds (NCRI- 05, IFE-1, NGAE- 96-012-3, NGAE -05 and AKURE -2-2) flour were investigated. The proximate composition shows that the moisture ranged from 11.08-13.35%; protein (18.37-19.36%); fat (12.79-13.55%); ash (2.13-4.40%); fibre (5.30-6.56%) and carbohydrate content (44.4-46.96%). The physicochemical properties revealed the bulk density to be between 0.11-0.22 g/cm3; swelling capacity (1.72-2.91mL); pH (5.28-5.59) and Titratable acidity (0.24-0.48%). The functional properties shows that water absorption capacity as 1.93 to 3.50 g/cm; oil absorption capacity (1.80-2.96 g/cm); emulsion capacity 2.25-3.44%); emulsion stability (1.15-1.81); foam capacity (4.33-6.4 cm) and foam stability (2.11-4.50%). The antioxidant activity shows the range of 18.62 to 38.26 and 25.56 to 152.88 for % inhibition of DPPH and Teac value respectively. Total phenolics and flavonoids 307-419.73 µg CE/g 61.33 - 81.72 µg CE/g respectively. The fermented okra seed flour showed an improvement in nutrient composition, antioxidant and some functional properties. Selecting a high protein variety of okra seed can have a good potential of being consumed as a complete diet or incorporated in human food in developing countries where protein foods are not adequate in supply. It can also serve as a functional ingredient in a variety of food formulations. Incorporation of okra seed flour in various food formulations will be beneficial to human health due to the improved antioxidant activity.

Keywords: Proximate composition, Functional properties, Antioxidant properties.
