The invention relates to a method of simultaneous purification and separation of pectin and pectic sugars/oligomers from sugar beet pulp using a multi-step process in an aqueous solution. The method comprises hydrolysis of the sugar beet pulp, solids separation from the sugar beet pulp hydrolysate as well as fractionation and desalting of the aqueous solution of the sugar beet pulp hydrolysate thus obtained into a desalted solution enriched in pectin and a desalted solution enriched in pectic sugars/oligomers. The process may also comprise optional further steps, such as clarification, adsorption, concentration and further chromatographic treatment.

Process for the fractionation of sugar beet pulp

The invention relates to chromatographic fractionation of pectin-containing vegetable material, such as sugar beet pulp. In the method of the invention, a pectin-containing hydrolysate is chromatographically separated into a pectin fraction, a salt fraction and a sugar fraction. The method is carried out by using a cation exchange resin, which is preferably in the form of a multivalent metal.
