ABSTRACT
This paper examines the physicochemical properties of starch extracted from seeds of Faidherbia albida collected form different locations within Sokoto metropolis. After extraction by hot water method, the starch was subjected to physicochemical analysis. The results of the analysis showed that the starch yield was 39.2% while the starch pH was 7.2. Also, the moisture content, ash content, starch protein, starch lipid, and amylose content of the starch were 7.3%, 0.02%, 0.72%, 0.27% and 26.7% respectively. Equally, the results showed that the swelling power, solubility and extent of amylose leaching were 10.7g/g, 2.9% and 5.9% respectively. Thus, the study concludes that F. albida starch may require some modifications in order to serve as a raw material for industrial products.
