Effect of Silicate Application on Grain Quality and Storage Characteristics in Rice

  • 4

This study was carried out to clarify the effect of silicate application on rice grain quality and storage characteristics in Ilpumbyeo cultivar. In yield and yield components, panicles and spikelet numbers were increased and ripened grain rate was also increased by 2%. Head rice yield was increased by 7.7~9.5% in silicate application. Protein content of milled rice was reduced by 0.2~0.3% and head rice rate was increased by 2.9~6.7% in silicate application due to decrease of chalky and damaged rice rate. In milling characteristics, color separation rate was improved by 4.2~7.2% and colored rice rate was decreased by 5.5~16.6% in silicate application. Acid value of stored brown rice were increased slowly in low temperature and silicate application, but that in room temperature and no silicate application was increased remarkably. The best degree rate of stored brown rice (over than 7.5 of pH) mea-sured by the pH of grain was increased by the silicate application in both low and room temperature. Therefore, it was suggested that the storage characteristics of rice grain was improved by the silicate application.
