  • Process of treating alcoholic beverages by vapor-arbitrated pervaporation
    Patent number: 5143526
    Abstract: The method and apparatus of the present invention has general applicability to the manipulation of the concentration, by partial depletion or enrichment, of one or more volatile components in a given liquid while leaving the other volatile components in the liquid in a substantially undisturbed or unadulterated state.
    Type: Grant
    Filed: May 2, 1991
    Date of Patent: September 1, 1992
    Assignee: Sepracor, Inc.
    Inventors: Eric K. Lee, Vinay J. Kalyani, Stephen L. Matson

  • Production of low-ethanol beverage by membrane extraction
    Patent number: 5013436
    Abstract: Low-ethanol wines, beer, distilled spirits, and other alcoholic beverages are produced by treating ordinary alcoholic beverages with novel membrane extraction methods. Semipermeable membranes and gas-phase extraction fluids are employed to selectively extract ethanol into the gas-phase, while leaving substantially intact the complement of other organic constituents that contribute to the color, aroma, and taste of the beverage. Methods are provided for balancing the water activity of the gas-phase extraction fluid about equal to that in the beverage, so as to inhibit water transport across the membrane independent of the ethanol/water selectivity of the membrane.
