A novel approach for the valorization of wine lees as a source of compounds able to modify wine properties
A De Iseppi, M Marangon, S Vincenzi, G Lomolino… - Lwt, 2021 - Elsevier
Wine lees, a sludge-like material mainly consisting of yeast cells, are rich in mannoproteins.
However, no reports on the extraction of mannoproteins from wine lees to be used as
winemaking additives are available. This study aimed at developing efficient methods for
yeast glycocompounds extraction from wine lees, and to assess their impacts when added
back to wine. White wine lees were extracted using physical (autoclave and ultrasonication)
and enzymatic (a β-glucanases) approaches. The autoclave extract was the richest in …
