| Abstract: | The suitability of sorghum as a starch source and its chemical
modification to carboxymethyl starch was investigated. The reaction conditions
during modification of starch such as reaction time and pH of the reaction medium were
optimized. Reaction time of 90 minutes at a pH of 10.5 results in maximum yield of
carboxymethyl starch. The functional properties of carboxymethyl starch like
swelling power, solubility characteristics and rheological properties were also
studied. The solubility and swelling power of modified starch were maximum at
70°C.
The viscosity of carboxymethyl starch was found to be several folds lower as
compared to native starch. The Sorghum genotype AK-809 starch is comparable to
corn in its starch content. |
