Abstract:
A method for processing a beet-derived sucrose-containing material, comprising the steps of:fractionating a beet-derived sucrose-containing material comprising a dissolved component in a first loop comprising a first fractionator into at least two fractions, the first of said fractions comprising a greater percentage of said dissolved component on a dry substance basis than any other fraction from said first fractionator, and said dissolved component selected from the group consisting of betaine, inositol, raffinose, galactinol, serine, and amino acid;fractionating a stream comprising said first fraction in a second loop comprising a second fractionator into a fraction comprising sucrose and another fraction comprising a greater percentage of said dissolved component on a dry substance basis than said first fraction; andsaid fractionators comprising a series of columns, beds, or parts thereof, said second fractionator having at least one column, bed, or part thereof, separate and distinct from said first fractionator;said fractionating in said first fractionator selected from the group consisting of a continuous chromatographic simulated moving bed process and a sequential chromatographic moving bed process;said fractionating in said second fractionator selected from the group consisting of a batch separation process, a continuous simulated chromatographic moving bed process, and a sequential simulated chromatographic moving bed process; andwherein said second fraction is subjected to evaporation prior to being fractionated in said second loop.
