  • Process of producing a fermentation product with reduced ethanol content
    Patent number: 5266337
    Abstract: The invention relates to a fermentation product with reduced ethanol content from sugar-containing fruit juices or other sugar-containing substrates, which is obtainable by the means that a first partial amount of the substrate having a content in fermentable sugars from 5 to 30% by wt. is treated for fermentation with 0.01 to 5% by weight of yeast (calculated as dry substance) and, if need be, with assimilable nitrogen and/or phosphorus compounds, and treated with 0.1 to 2 volume parts of air or amount of oxygen equivalent to air per volume part and minute, until there has been established in the substrate an ethanol content of 1 to 10% by vol., in particular up to 7.5% by vol.; whereupon a second partial amount of the substrated is dosed in under continued gassing with air or with oxygen.
