Abstract


This research work investigated the effect of processing (sulphiting and steam blanching) on the proximate, phytochemical and functional properties of Dioscorea bulbifera flour. the There were significant (𝑃 < 0.05) differences in the proximate composition in all the samples. Steam blanching significantly increased crude fibre, protein, ash and carbohydrate when compared with the raw and sulphited samples.  Alkaloid, flavonoid and saponin contents ranged from 2.04-3.63, 8.84 -12.34 and 0.46-0.73 in the steam blanched samples. Sulphiting significantly increased the phytate and carotenoid contents from 0.24 -0.82 and 0.08 -4.83 respectively. Steam blanching significantly (𝑃 < 0.05) increased the water absorption capacity, swelling capacity and least gelation capacity compared to the raw and sulphited sample.
