Samples were rehydrated at 30℃ for 2 hours after dried by different methods
Sun drying, dried at 25℃ and RH 65% for 48 hr; Hot-air drying, dried at 50℃ in for 14 hr; Freeze-drying, freeze-dried by vacuum freeze dryer.
Means with different small letters (a-c) in the same column are significantly different at p<0.05 by Duncan's multiple range test.
