The effect of dehydration in saccharose or starch medium at 30°C and 80°C on the kinetics of convection drying of apples (Idared or Lobo variety) was studied. Osmotic pre-treatment was shown to cut down the drying time of apples with the dry weight moisture content of about 3 g H20/g after dehydration. The water removal rate during drying decreased independent of the degree of dehydration in either...
