Abstract: Mannoprotein abstracted from spent yeast has shown significant effect to wine tartar stability when added into wine.It could keep the tartar stable in white wine, but it showed no effect to the tartar in red wine. When mannoprotein was added intowine, the conductivity of the wine would increase. The descendant value of conductivity would fall when using the POLAR POINTMINI CONTACT to check the cold stability of the wine. When excessive mannoprotein was added, the possibility of non-crystal precipitation would increase.

Key words: mannoprotein, wine, tartar stability
