Vacuum drying usually can heat foods up to 98–102°C, with low pressure of 25–100 mm Hg [1,14]. Lower temperatures (60–70°C) are used for high-sugar food products to prevent decomposition [1,7,14,18]. Moisture can be evaporated more quickly at the reduced pressure, and drying times can be dramatically reduced [1].
