Hammami et al. [4.27] determined 0.5 mbar and rSh = 55 °C as the optimum (for quality and operational data) drying conditions for the freeze-drying of apple slices, loaded with 17 kg/m2 and dried in 48-50 h. The rehydration ratio was -0.55 g/g of water removed and the texture loss of rehydrated apples was estimated to be more than 85%. Sa et al. [4.28] used DSC to measure the Tg of freeze-dried Golden Delicious apples after exposure to aw from 0.12 to 0.93. The sorption isotherms are reported.

Enzymatic procedures were also reported for the recovery of organo-As species. A two-step procedure for the extraction of As from freeze-dried apples using a treatment with a-amylase enzyme followed by sonication with 40 percent acetonitrile was found to provide good extraction efbciency [44],...

It has been shown that apples dried by osmosis and then frozen compared favorably with the conventional frozen fruits [144,179], Osmotic dehydration preceding freeze drying shortens the time of the process and yields fruits superior to those not treated by osmosis [15,79,97], Osmotic dehydration followed by vacuum drying gives products that are very stable upon storage [65],...
