Abstract
Pentaclethramacrophylla (African oil bean) seed is a prominent tropical tree plant in Nigeria belonging to the family leguminosae and mimosoidaesub-family, and used to supplement starch sustenance’s, and other nourishment. The present study assessed the functional properties of protein isolates from the seeds of P.macrophylla using standard methods while simple statistical analysis was used to evaluate the results. From the results, the seeds protein had in gg-1an oil absorption capacity, emulsifying capacity and emulsion stability of 148.57±1.82, 80±0 and 44.78±3.22, respectively. The bulk and tapped density were 0.49±0.01and 0.57±0.02g/ml in that order. The effects of a temperature range of 60-90oC on swelling power and solubility index were 366.61±126.73to 280.56±5.57 g/g and 10.71±9.48to 5.73±1.03 g/g. The effects of NaCl concentration and pH value of a range of 0.1-2.0 M and 2-14 on water absorption capacity were 288.4±14.57 to 237.9±15.98 g/g and 329.8±67.60to 785.2±14.14 g/g. The least gelation concentration of protein isolates was found to be 3%, and the minimum and maximum nitrogen solubility were 8.75±2.89% at pH 6 and 131.25±0.35% at pH 2, respectively. The data generated for the effect of salt concentration and pH on water absorption capacity showed that both the salt and pH might be used to enhance the functionalities of the protein flour. The results obtained in this study compared favourably with previous studies on protein isolates from other seed plants.
