  • Method for processing aqueous sugar juice for separating ketose
    Patent number: 4785794
    Abstract: A method for processing aqueous sugar juice containing a mixture of aldehyde-function saccharides and ketonic-function saccharides for separating and selecting ketonic-function saccharides, comprising (a) producing a hydro-organic medium by mixing the juice with an active methylene ketonic compound, a calcium-based catalyst and preferably ethanol, (b) mixing the medium until furanic polyalcohol is formed by condensation of the ketonic compound and the aldehyde-function saccharides and (c) allowing the furanic polyalcohol to precipitate and separating it by physical means from the liquid medium.
