Physico-chemical investigations on varietal differences in rice
- 8 Downloads
The increase in conductivity with time of rice and rice powder suspensions in water has been studied at different temperatures. Varietal differences in the rates of increase have been observed, but they are not characteristic of quality. The increase in conductivity cannot be attributed to electrolytes liberated by hydrolysis of amylopectin as such hydrolysis is inappreciable, but is to be accounted for, by the dissolution of electrolytes already present in the free state in rice.
