Proton mobility for the description of dynamic aspects of freeze-dried fruits

The partitioning of water sorption isotherms into different zones, according to the strength of water interactions with solids has very important practical applications. However, the dynamic properties of water play an important role in complementing the information provided by water sorption isothe...
