Abstract: Hot air-assisted radio frequency（HA-RF） disinfestation effects for rough rice had been validated, to explore its application potential on simultaneously disinfestation and drying, this study focused on the HA-RF drying efficacy for rough rice, and developed the HA-RF drying technique and investigated the associated quality changes. Results indicated that the optimal HA-RF drying technology was: electrode gap 10.0 cm（RF heating rate:6.10 ℃/min）, drying temperature 60 ℃ and sample thickness 3.0 cm, HA-RF drying could reduce the drying time by 34.6% and lower unit energy consumption compared with HA drying. Besides, HA-RF drying had no significant difference on the effect on head rice yield（HRY）, total rice yield（TRY） and fissure ratio compared with HA drying. However HA-RF drying better maintained Vitamin E content and had less influence on color and microstructure of milled rice. This study indicated that HA-RF was a more efficient drying method for rough rice than HA drying, and had better product quality, thus it holds application potential in simultaneously disinfestation and drying of rough rice.
