Water and almost all ethanol were eliminated during freeze-drying leaving an amorphous glassy maltodextrin microstructure (i.e., "wine powder”), containing the red wine's polyphenols (as well as other non-volatile constituents of the dry extract). Almost no loss of total polyphenols was found in the freeze-drying process. Upon milling, the maltodextrin microstructure yielded a free-flowing powder, and its glassy nature was confirmed by measuring its glass transition temperature (T g). After 15days, storage at 38°C total polyphenols content in the "wine powder” remained practically unchanged. This free-flowing powder contained 3.7 times the concentration of polyphenols in red wine, while only containing less than 1% ethanol. This might be added to other powdered foods as a source of wine polyphenols.
