ABSTRACT:
A process for purifying polydextrose to remove contaminants remaining from manufacturing sufficient to provide an organoleptically-acceptable polydextrose ingredient for foodstuffs which includes intimately contacting an aqueous solution of polydextrose having a concentration of from about 10% to about 50% with a polar organic solvent in a ratio of polydextgrose solvent of from about 5-15 of polydextrose to about 45-75 by weight of solvent. Furthermore, the mixture is allowed to equilibrate to form a substantially contaminant-containing fraction and a substantially polydextrose-containing fraction, followed by separating the fractions for use of the polydextrose-containing fraction. The present invention further includes compositions of foodstuffs including the purified polydextrose.
