Starch from the rhizomes of Canna edulis was isolated, purified and its physico‐chemical properties are compared with maize starch. Scanning electron microscopy of the granules show that they are oval to eliptical in shape. It has low contents of lipids, ash and proteins, and has significantly higher content of amylose. It displays low water‐binding capacity and gelatinization temperature. Swelling and solubility are higher when compared with maize starch. Brabender viscosity of C. edulis starch is more than three times higher than maize starch and has shown no thinning. It retrogrades more than maize starch.
