Mathematical modeling results showed that Logarithmic model and Two-term model werthe best in describing HA and SMIR drying process of jujube slices, respectively. Value of D
increased gradually to the maximum value then declined as the decrease of moisture content (db), and higher temperature resulted in higher value of Deff. Jujube slices dried by SMIR showed lower “△E”, higher contents of VC, TFC and cAMP than HA drying. SMIR drying was a more effective and promising drying method for jujube.
