Optimization of Lotus Root Heat Pump Drying Process and Quality Evaluation of Whole Lotus Root Powder
In order to solve the problems of postharvest quality degradation of fresh lotus root,using lotus root as material,taking the drying rate,rehydration property,color of lotus root powder,and moisture content as indicators,the effects of slicing thickness,drying temperature,and loading capacity on the quality of dried lotus root and lotus root powder were studied.The optimal condition for drying lotus root heat pump was that the temperature was 70 ℃,the slice thickness was 5 mm and the loading capacity was 3 kg/m2.The drying rate of dry lotus root flakes was faster,the rehydration was better,the lotus root pink color was bright and the water content was low.The experiment will process fresh lotus roots into whole lotus root powder,which can effectively preserve the nutrients of lotus roots,and provide theoretical basis for post-harvest storage and processing of lotus roots.
