Abstract: Vitamin-fortified extruded rice grains were packed in different packages and stored in different storage conditions, and the changes of vitamins, moisture content and acid value during storage were determined. Results showed that packages and storage conditions had effects on the changes of above indices in the rice during storage. The optimal storage conditions are that the vitamin-fortified extruded rice grains are stored at 4 ℃ in tinplate can. More than 80% of VC and VD3, 95% of VB in the rice remained after stored under the optimal conditions for 180 d, with the acid value below 1.0 mg/g and the water contents below 8%.

Key words: vitamin-fortified extruded rice grain, nutrients, storage conditions, storage stability
