| Abstract: | Objective] Growing period of Amorphophallus konjac powder was appraised using thermal analysis method. Method] The TG-DTG curves of Amorphophallus konjac powder of one year growing period,two years growing period and three years growing period were analyzed using TG-DTG technique in the static air. Result] Amorphophallus konjac powder was carbonized when the temperature was at 259.0-261.0 ℃ and it was burned when the temperature was 433.0-450.8 ℃. The DTG curves of Amorphophallus konjac powder of different growing period were different. Conclusion] It was easy to distinguish the Amorphophallus konjac powder of different growing period according to the mass lessen peak position in the DTG curves. |
