Trehalose desiccant product and dehydration therewith

摘要

Disclosed are a novel desiccant containing a non-reducing anhydrous trehalose as an effective ingredient; a dehydration of hydrous matters, e. g. food products, pharmaceuticals and cosmetics, therewith; and dehydrated products obtained by the dehydration. Such hydrous matters are dehydrated without causing alteration or deterioration by incorporating anhydrous trehalose into the hydrous matters to convert the anhydrous trehalose into hydrous crystalline trehalose. The anhydrous trehalose are anhydrous crystalline trehalose and hydrous amorphous trehalose.
