Abstract
This work studied the functional properties of native and acetylated carton brown and horse red cowpea starches as potential substitutes for conventional starches. Starch acetates were prepared by reacting previously isolated native cowpea starches with acetic anhydride using established method. Functional properties studied included the effects of temperature and pH on swelling power and solubility, water and oil absorption capacities, gelation properties, light transmittance and pasting properties. The starch acetates prepared had higher swelling and water absorption capacities than the native starches. Acetylation improved the gelling property of acetylated horse red starch. Light transmittance of all starches decreased with increase in the period of storage. Pasting properties of modified starches significantly reduced (p<0.05). Functional properties of native and acetylated cowpea starches showed that the local cowpeas are potential industrial raw materials.
