Recovery of Compressed Dehydrated Foods. Phase 2
Abstract
Twelve foods, along and in combination, were frozen at various rates, freeze-dried in different ways and brought to certain predetermined water contents by exposure, via the vapor phase, to water at controlled activities (aw's). The moist freeze-dried materials were subjected to compression and to further drying, after which they were rehydrated. Freeze-drying by sublimation and direct desorption of remaining water to various predetermined water activities was subjected to further analysis. Supplementary studies were completed in continued attempts to define factors responsible for recovery.
