An enzymatically produced soluble -glucan fiber composition is provided suitable for use as a digestion resistant fiber in food and feed applications. The soluble -glucan fiber composition can be blended with one or more additional food ingredients to produce fiber-containing compositions. Methods for the production and use of compositions comprising the soluble -glucan fiber are also provided.

Use of an unmodified specialty corn starch obtained from a corn endosperm having three copies of the recessive waxy gene (wx) and two copies of the recessive amylose extender gene (ae). The starch is useful in food compositions. The composition comprises an unmodified aewx corn starch in an amount about 0.1% (wt. % of the composition); an aqueous component; and a third ingredient wherein optionally, the third ingredient is selected from the group consisting of a protein, a second starch, a hydrocolloid and mixtures thereof. In at least some compositions the unmodified starch is used to form a thermally reversible gels.
