Abstract

Chemical modification is usually carried out to overcome the unstable properties of plant starches and improve their physical and functional characteristics during processing. Alum modification at different concentrations (1.0%, 2.0%, 3.0%, 4.0% and 5.0% w/v) with and without 10ml of IM sodium hydroxide at room temperature was carried out. Cassava starch treated with 3.5% of alum showed a profound influence on pasting properties compared to the native starch in that it exhibited a reduction in the peak viscosity of the modified cassava starch increased. Alum modification also freeze-thaw stability.
