| Abstract: | A pilot plant system for dealcoholizing wine using solid carbon dioxide snow was evaluated. Wines were stripped of alcohol content by spraying them over solid phase CO2. Gas leaving the solid-liquid contact zone carried ethanol which was recovered by condensation. White wine lost alcohol easier than red wine and some higher alcohols were removed at levels which paralleled ethanol removal. Other solutes remained at about the same levels as in the untreated wine. |
