Abstract

Claims33
An improved water-soluble highly-branched polydextrose wherein the linkage 1.fwdarw.6 predominates, having number average molecular weight between 1,500 and 18,000 and having been prepared by a process which comprises melting dextrose at a temperature below its decomposition point in the presence of 0.5 to 3.0 mol percent of citric acid, the improvement comprising a bound citric acid content of 0.3 mol percent or less in said improved polydextrose to decrease bitterness.
A water-soluble highly-branched polydextrose having been prepared by the sequential steps comprising (a) melting a mixture comprising dextrose at a temperature below its decomposition point in the presence of from about 0.5 to 3 mol percent of citric acid;
- and (b) reducing the content of citric acid bound in the form of ester groups to 0.3 mol percent or less.
A polydextrose composition substantially free of bitter-tasting residual compounds made by the process consisting essentially of:
- a) dissolving polydextrose in water;
- b) passing said solution through an ion-exchange column;
- and
- c) collecting and concentrating the eluate produced thereby until a commercially useful polydextrose composition is recovered.
A polydextrose bulking agent useful for incorporation in reduced calorie foods, substantially free of bitter-tasting compounds.
