This study investigated the influences of paddy aging at 60 C and 70% relative humidity for 5 days on pasting properties of rice flours and molecular structures of major constituents in rice grain. The rice cultivars investigated included waxy rice Sanpah-Tawng 1 (SPT1), which contained 1.3% amylose and 8.3% protein. Non-waxy rice paddies; namely Pathum Thani 1 (PTT1), which had 14.1% amylose and 6.7% protein, as well as and Leuang Pratew 123 (LPT123), which contained 28.6% amylose and 9.6% protein, were also investigated. Paddy aging significantly changed the RVA pasting characteristics of rice flour pastes from all cultivars investigated (p<0.05). All aged rice flour pastes had higher final viscosity than that of new rice flour paste. Fourier... |
