Starch Based Fat-Replacer by Crystallization of Enzyme Modified Starch and High-Pressure Shearing

Abstract

We disclose a composition comprising greater than about 95% d.s.b. of a starch comprising short chain amylose having an average degree of polymerization (DP) from about 20 to about 150, wherein an aqueous slurry comprising about 20% d.s.b. of the composition has a minimum yield stress of at least 400 Pa. We also disclose a method of preparing the composition comprising contacting a starch paste with a 4-α-glucanotransferase, to yield a chain-extended starch; contacting the chain-extended starch with a debranching enzyme, to yield a debranched starch; crystallizing the debranched starch, to yield a crystallized debranched starch; and shearing the crystallized debranched starch, to yield the composition. We also disclose a food formulation comprising a foodstuff and the composition.
