The storage of whole rice with brown, black, and red pericarp for 6 months at 40 C resulted in a decrease in the extraction yield of starch and loss of the characteristic color of starch, which industrially limits its use in applications where clarity of paste is important. There was reduction in amylose content of starch isolated from grains stored for 6 months at 40 C compared to that of starch isolated from grains at the 1st day of storage. These storage conditions also showed the maximum reduction in solubility and retrogradation, possibly due to the action of amylolytic enzymes. Storage at 40 C also reduced crystallinity, which facilitates gelatinization, as measured by reducing the enthalpy of gelatinization. Reductions in peak viscosity and final viscosity of starch isolated from grains stored at 40 C are possibly caused by interactions between starch and amino acids. Grain stored at 16 C showed the least number of changes in the starch properties.
