Starches from the seeds of C. arborea and A. assamica were isolated, bleached, purified and their physicochemical properties were compared with maize starch. SEM of the granules showed oval shape of C. arborea starch and elliptical for A. assamica starch. Amylose content of C. arborea was less than A. assamica starch but comparable with maize starch. Gelatinisation temperature of both the starches was higher than maize starch, swelling was comparable and solubility of both was considerably higher. Brabender viscosity curves showed almost the same peak viscosity for both the starches but lesser than maize starch. Retrogradation of C. arborea starch was significantly higher than A. assamica starch.
