摘要

为解决新鲜莲藕采后易霉变、品质下降等问题,以莲藕为原料,以藕片干燥速率、复水性,藕粉色泽、水分含量为指标,研究切片厚度、干燥温度和装载量对干燥后莲藕和全藕粉品质的影响.结果表明,当干燥温度70℃、切片厚度5 mm、装载量3 kg/m2时,藕片干燥速率较快、复水性较好,全藕粉色泽鲜亮,含水量较低,为莲藕热泵干燥的最优条件.试验将新鲜莲藕加工成全藕粉,可有效保留莲藕的营养成分,为莲藕采后贮藏和加工提供理论依据.

Abstract

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.
