“…Namely, a freeze-dried sugar sample contains a large number of cylindrical pores that had been occupied by ice crystals and the pores serve as channels for the water vapor permeation. Compression substantially decreases the number of pores present in a sample (Imamura et al, 2010) and thus lowers the water diffusivity relative to that for an uncompressed sample. However, the remaining pores in the compressed sample results in the water diffusivity being higher than that for a nonporous sugar paste.…”

“…Our previous study demonstrated that the compression at hundreds of MPa markedly decreased the surface area of freezedried sugar samples (Imamura et al, 2010). Taking into account the fact that water sorption involves "adsorption" on the surface as well as "absorption" into the bulk, the decrease in water content as the result of the compression (Fig.…”

“…Processes, such as milling, spray-drying, and compaction, may lead to phase change of organic solids (25)(26)(27)(28)(29). We therefore examine materials after both jetmilling and spray-drying to ensure phase stability of ACM.…”
