The present invention relates to a method of separating sugars and sugar alcohols from each other. More particularly the present invention relates to the use of a weakly basic anion exchange resin in a chromatographic separation process. The advantage of the present invention compared with the prior art is that it is especially suitable for separating reducing sugars in acidic conditions as well as for example in weakly acidic conditions. The method using chromatographic separation comprises at least one step where a weakly basic anion exchange resin is used in a chromatographic column or in a part of a column.

Separation of sugars, sugar alcohols, carbohydrates and mixtures thereof

The invention relates to a system and a process for fractionating a solution into two or more fractions. The system of the invention comprises at least two compartments having a diameter of at least about one meter and including a uniform packing of a polymer-based ion exchange resin with a bead size in the range of about 50 to about 250 &#x3bc;m. The mixing volume of the fluid fronts in the system of the invention is not more than 5% of the volume of the compartment.

Separation system and process

The invention relates to the use of a weakly acid cation exchange resin for chromatographic separation of carbohydrates. In the invention the hydrophilic/hydrophobic interaction of carbohydrates, sugars and sugar alcohols with the weakly acid cation exchange resin is utilized. The weakly acid cation exchange resin is used for separation of hydrophobic saccharides, such as deoxy, methyl and anhydrosugars and anhydrosugaralcohols from more hydrophilic saccharides.
