Hot-air and freeze dried powder from aged black ginger were mixed under the ratio conditions of sample ¡°A¡± (8:2), ¡°B¡± (5:5), ¡°C¡±(2:8), ¡°D¡± (10:0) and ¡°E¡± (0:10), respectively. The physicochemical properties and antioxidant activities in the 5 kinds of powder were compared. The water absorption index was significantly higher in freeze dried powder, and it tended to be significantly increased depend on the ratio of freeze dried sample. The browning intensity was significantly higher in the hot-air dried samples, but the color intensity was not significant. Total and reducing sugar contents were significantly higher in freeze dried sample. Total sugar content in mixed sample tended to significantly increased as the amount of freeze dried sample. Total phenol content was significantly higher in the sample ¡°A¡±. The contents of gingerol and shogaol were significantly higher in mixed sample ¡°A¡±, 6-gingerol content showed no significant difference according to the drying method. Cholesterol absorption activity was significantly higher in the freeze dried sample ¡°E¡±. The DPPH radical scavenging activity showed a little difference according to the drying method, but the ABTS radical scavenging activity and reducing power in the hot-air dried sample were significantly higher than those of freeze dried. And the activity of mixed powder ¡°A¡± was significantly higher than others. These results suggest that aged black ginger was superior in terms of quality and functionality of the hot-air drying compared to freeze-drying, and it would be economically effective to the mixed sample ¡°A¡±.
