The dried product also provided excellent taste and flavor with no shrinkage or change in color (Drouzas & Schubert, 1996). In microwave vacuum drying of model fruit gel (simulated concentrated orange juice), a reduction in the moisture content from 38.4% to less than 3% was achieved in less than 4 min whereas conventional air drying took more than 8 h to reach 10% moisture (Drouzas, Tsami, & Saravacos, 1999).
