Recently, fluidized bed drying has been proposed to perform the process of rice drying (Poomsa-ad et al., 2002 and Poomsa-sa et al., 2005) and their works showed that the head rice yield after drying could be maintained or even higher than that before drying. The information about this technique to the rice aging process has not been reported in the literature. Therefore, the accelerated rice aging by fluidized bed drying was studied at the present work. Since there is some loss of paddy moisture content during fluidized bed drying, which is generally not desirable, the initial moisture content and treatment temperature are important operating parameters that must be considered when aging rice using this technique.
