Abstract
Dextrins are prepared by hydrolyzing starch with an enzyme that consists essentially of a beta-amylase enzyme. The product prepared thereby will include a dextrin, such as beta-limit dextrin. Upon ultrafiltration of this product, a dextrin-rich fraction may be recovered. If desired, the dextrin-rich fraction may be further purified via diafiltration. Retrograded amylose may be separated from the product of enzymatic hydrolysis.
Claims3
A method for preparing a dextrin product, comprising:
- treating a starch with an enzyme that consists essentially of a beta-amylase enzyme under conditions suitable to form a product mixture that includes a dextrin, retrograded amylose, and at least one sugar having a degree of polymerization less than 10;
- allowing at least a portion of said retrograded amylose to crystallize from said mixture;
- separating the crystallized retrograded amylose from said mixture;
- and
- recovering a dextrin rich fraction from said product mixture via ultrafiltration.
