The results of analyses of chemical composition, morphology &
granule size distribution, thermal properties, paste & gel properties,
crystalline pattern and molecular structure of amylose and
amylopectin of starches from 12 cassava varieties having different
cooked root textures led to the conclusion that there were no
significant differences in properties of starch among the all varieties.
This indicated that the differences in cooked root texture were
not influenced by the qualities of starch. In the case of flours, there
were wider variations in these properties than in the starches.
Quite strong correlations were found between firmness and
a-amylase activity, firmness and fiber and lipid contents, as well as
paste viscosity and ash, starch content, and a-amylase activity. That
implied that the non-starch components in flours may influence
the texture of cooked cassava roots.
