摘　　要：蒲公英作为一种既可食用,又可药用的植物,是具有开发前景和广泛应用的经济作物资源。针对传统干燥存在生产效率低、能耗大、卫生条件差、贮藏期品质下降等缺陷问题。运用对干制品影响较小的振动远红外干燥方法对蒲公英进行干燥试验研究,采用单因素和二次通用旋转组合试验设计方法,探讨加热温度、振动频率、物料厚度对蒲公英复水比、褐变程度和黄酮含量的影响规律,建立了各指标与试验因素间的回归数学模型。采用加权综合评分法和线性功效系数法,将多目标综合优化,确定干燥工艺的最优参数,即加热温度74℃,振动频率0.8 Hz,物料厚度7 mm时,复水比(Rf)为3.88,褐变程度为14.50,黄酮含量为1.89%,综合评分为0.825。研究为振动远红外干燥蒲公英技术提供了试验研究基础和理论依据。As a kind of edible and medicinal plant,dandelion is a cash crop resource with development prospects and wide application.In view of the defects of traditional drying,such as low production efficiency,high energy consumption,poor sanitary conditions,and decline in quality during storage,the vibration far-infrared drying method,which has little effect on dry products,was used to conduct drying experiments on dandelion.The single factor and the second general rotation combined test design method was used to explore the influence of heating temperature,vibration frequency,material thickness on the rehydration ratio,browning degree and flavone content of dandelion,and a regression mathematical model between each index and the test factors was established.The weighted comprehensive scoring method and linear efficacy coefficient method were used to comprehensively optimize the multi-objective and determine the optimal parameters of the drying process,that is,the heating temperature was 74℃,the vibration frequency was 0.8 Hz,the material thickness was 7 mm,the water recovery ratio(Rf)was 3.88,the browning degree was 14.50,the flavone content was 1.89%,and the comprehensive score was 0.825.It provideds experimental and theoretical basis for vibration far infrared drying of dandelion.
