Polysaccharide effects on cross-flow microfiltration of two red wines with a microporous alumina membrane

Two red wines, from the same cultivar, differing by polysaccharide content were filtered using cross-flow microfiltration with an alumina membrane, pore size 0.2 micromole. Filtration flow rates were different. The wine richest in polysaccharides (A) showed a typical external fouling profile with pr...

Summary:Two red wines, from the same cultivar, differing by polysaccharide content were filtered using cross-flow microfiltration with an alumina membrane, pore size 0.2 micromole. Filtration flow rates were different. The wine richest in polysaccharides (A) showed a typical external fouling profile with progressive stabilization, while wine B showed a permanent decrease in flux (external and internal fouling). Retention of polysaccharides negatively correlated with their hydrodynamic volume, overall losses being higher for wine B. Polysaccharides had a possible role in fouling related to their structures and molecular weight distribution in the two wines
