  • Abstract:

The study aimed to explore the potential of African locust bean pulp, which is usually washed off during processing of
iru, as a food and functional materials in food application. The proximate composition, pH, functional properties,
pasting properties and phytochemical composition of African locust bean pulp were determined using standard
methods. The pulp contained 7.96% crude protein, 2.56% crude fat, 6.97% crude fibre, 2.69% ash, 7.14% moisture
and 72.68% carbohydrate. The pH, swelling power, water absorption capacity, oil absorption capacity, least gelation
concentration, wettability and bulk densityof the pulp were 4.1, 4.98 g/g, 4.80ml/g, 2.40ml/g, 8.00%, 1.22 mins and
0.36g/ml, respectively. The peak viscosity (85cP), trough viscosity (80cP) and final viscosity (122cP) of the pulp were
low indicating low starch content with poor pasting profile.Phytochemical analysis showed the presence of tannin
(5.53mg/g), flavonoid (4.72mg/g), steroid (18.37mg/g), terpenoid (10.35mg/g), alkaloid (45.02%) and cardiac
glycosides (8.22mg/g).The results suggest that African locust bean pulp could be a potential food and functional
material in food processing.
