Abstract:
1. An apparatus for removing at least one solute selected from the group consisting of ethyl acetate and acetic acid from an untreated wine alcoholic beverage comprising: a receptacle containing the untreated wine alcoholic beverage; a nano-filtration unit in fluid communication with the receptacle; a pump for driving the untreated wine alcoholic beverage through the nano-filtration unit to produce a retentate at a retentate outlet and a raw permeate at a raw permeate outlet, wherein the raw permeate contains an increased concentration of the at least one solute selected from the group consisting of ethyl acetate and acetic acid; a treatment column selected from at least one member of the group consisting of an ion exchange column, a hydrophobic interaction column, an affinity column, a gel filtration-column, and a gel exclusion column for absorbing at least a portion of the at least one solute from the raw permeate, the treatment column having an inlet in fluid communication with the raw permeate outlet of the nano-filtration unit and a treated permeate effluent outlet in fluid communication with the retentate outlet for combining the retentate egressing from the retentate outlet with the treated permeate egressing from the treated permeate effluent outlet to provide a treated wine as an alcoholic beverage, the apparatus for single pass nanofiltration.
