PURPOSE:To prepare an alcohol-containing fruit juice drink having unique taste and flavor, by using an ultrafiltration membrane device in the course of the alcoholic fermentation of fruit juice. CONSTITUTION:In the alcoholic fermentation of fruit juice, the alcohol-containing fruit juice is separated by using an ultrafiltration membrane device prior to the completion of the fermentation, i.e. the comsumption of the sugar in the fruit juice reaches >=10% and <100%. The separated fruit juice is used in the preparation of a fruit juice drink having desired alcohol concentration, e.g. a fruit juice drink having an alcohol content of <1% in the final product. The fruit juice is the juice prepared by pressing the fruit of orange, apple, grape, etc., the juice of the fruit centrifuged to remove the solid component, concentrated juice, or sugared juice, etc. The ultrafiltration membrane is a synthetic resin membrane such as polyvinyl alcohol, polyester, polyacrylonitrile, etc. |
