Abstract
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.
Claims28
A method of treating pectin-containing vegetable material which is in the form of a pectin-containing aqueous solution, comprising introducing the pectin-containing solution into a chromatographic column including a cation exhange resin and separating the pectin-containing solution into a fraction having a higher pectin content than the pectin-containing solution introduced into the chromatographic column, and into at least one other fraction, using water as the eluant.
