Physicochemical Properties of Starches obtained from Anchomanes difformis and Tacca involucrata Tubers.

Anchomanes difformis and Tacca involucrata are wild tuberous plants rich in starch.  Starches were isolated from the tubers of these plants using the wet milling method of extraction and were subjected to physicochemical characterization by standard experimental procedures. Anchomanes difformis afforded starch with a percentage yield of 28.15% while T. involucrata yielded 12.25% starch. The physicochemical analysis of the starches revealed a swelling power of 8.5 and 12.0, gelatinization temperature of 73˚C and 750C, pasting temperature of 79.96˚C and 77.890C, with a pH of 5.8 and 6.5 and bulk density 0.77 g/cm3 and 0.76 for A. difformis and T. involucrata respectively. The microscopic and x-ray diffraction analysis indicates that the starch granules are generally small in size, with clustered arrangement. This study has revealed that both A. difformis and T. involucrata are not only rich in starch, but that the starches have high potential for industrial applications and could serve as alternative sources to avoid competition with the staple crop, cassava.
