Abstract:The purpose of this study was to ensure the efficient drying and superior quality of taro rounds.The diameter of taro round，microwave power，and intermittent ratio were considered as the influential factors，and the comprehensive score of the membership degree of the four indexes，namely，rehydration ratio，sensory score，cooking time，and total drying time，was used as the evaluation index.The technological conditions of microwave intermittent drying of taro rounds were optimized through single factor experiments and response surface test.The results showed that the order of effects of the selected experimental factors on the comprehensive score of membership degree was as follows：diameter of taro round>microwave power>intermittent ratio.Moreover，the optimal parameters were as follows：diameter of taro round was 0.8 cm，microwave power was 350 W，and intermittent ratio was 2.0.Under these conditions，the quality of dried taro round was the best，and the comprehensive score of membership degree was 2.417±0.007.
