Abstract
Abstract Process for fractionating carbohydrate-containing materials, such as molasses, by contact with an ion exclusion resin wherein a first portion of the material and a second, less dense portion of the material are sequentially fed to the resin. This scheme of adding the carbohydrate-containing material to the column of ion exclusion resin lessens the channeling problem. Also, a process for treating molasses comprising adding ferric ions to the molasses to form a precipitate and passing the so-treated molasses through an ion exclusion resin.
