| Abstract: | We developed a technique for storing rice below ice point using natural coldness. We conducted a basic study to examine the effect of storage temperature on the overall quality of Japonica rice. Rice storage experiments on a laboratory scale were carried out at environment temperature, low temperature (below 15°C), ice point and at −15°C. The results showed that the rice storage at −15°C preserved rice quality. Next, a rice storage experiment on a farm scale was conducted. A total of 378 metric tons of rough rice was stored in a farm-scale silo and aerated for 113 hours in February. The temperature of the rough rice in the silo fell below ice point. The temperature of the rough rice in the middle of the silo remained below ice point until July. The quality of the stored rice was consequently preserved at a level similar to that of freshly harvested rice even after 9 months of storage. A combination of rice storage below ice point and natural coldness in winter could be used as a new technique to preserve the rice quality without the need of a cooling unit or electricity. |
