Zhangxi taros were removed the peel,sliced,cooked,dried by sunshine (about 35℃),and hot air (about 60℃,70℃,100℃),smashed to taro powder.The effect of drying conditions on the quality of taro powder was researched with some parameters,such as color,moisture,water absorption,oil absorptivity,total sugar,protein and particle dispersion,as the indexes.The results showed that the optimal comprehensive quality of the taro powder was that dried by 60℃ low temperature hot air,with lighter color,uniform particle size,good dispersion,high content of nutrient compositions,good water absorption and oil absorbency.
