Abstract
The present invention relates to a chromatographic separation process for fractionating solutions containing sugars, sugar alcohols, sugar acids and/or betaine by utilizing fractions comprising parts of the separation profile as a substituent of the eluent in a novel and inventive manner. The starting solutions are typically multicomponent plant-based extracts and hydrolysates, stillages, and fermentation products and derivatives thereof. The process prow vides improved separation capacity and separation efficiency without affecting the yield or purity of product components, such as sugars, sugar alcohols, sugar acids, and betaine. The process can especially be applied to sequential SMB separation systems.
