| Paddy storage may cause considerable losses and changes in quality of rice. The objective of this study is to determine changes in some physical and chemical properties of rice grains during storage. The experiment was conducted at Pathumthani Rice Research Center during May 2012 – January 2013. PTT1 variety was used for low amylose rice, and PSL2 for high amylose. Samples were taken and stored in 2 kg woven plastic sack at room temperature. The PTT1 and PSL2 samples were stored for 8 and 6 months, respectively. Changes in the physical and chemical properties of rice grains were observed. The paddy samples increased in percentage of head rice, yellow grains and fat acidity, while whiteness of milled rice decreased. But amylose content and percentage of... |
