Abstract
Starch finds use in a myriad of industrial applications. In its native form however, its functionalities are limited. In this study, starch was isolated from Treculia africana, a lesser-known starch source, kernels and modified to produce the acetylated, oxidized, and acid-thinned derivatives. The effects of modifications on the native starch chemical properties, swelling power and solubility, water and oil absorption capacities, gelation, and morphological were investigated. Significant (p < 0.05) reductions in the native starch moisture, ash, crude protein, crude fat, and crude fibre compositions were observed. Starches increased in swelling power and solubilities with increase in temperature. The oxidised starch showed the most significant increase (p < 0.05) in oil absorption capacity while the native starch had better water absorption capacity than the modified starches. Improved gelation property was most significant in the acid-thinned starch. Scanning electron microscopy, showed oblong and oval starch granules with rough surface morphology with no significant differences for the native and derivatised starches. The study showed that modification improved T. africana kernel starch properties.
