Abstract
Conditions for the preparation of half esters of corn and small sized (1–2 μm) waxy amaranth starch using succinic anhydride were compared in a non-aqueous medium. The synthesis was followed in terms of % succinyl content and the degree of substitution (DS). The parameters optimised included succinic anhydride concentration, reaction time and starch/pyridine ratio required in the process. Succinate derivatives from both the starches gave DS as a function of the succinic anhydride concentration and reaction time. A starch/pyridine ratio of 1:2 was found to be necessary for the reaction to be carried out smoothly.
