PRODUCTION OF ENZYME-RESISTANT STARCH BY EXTRUSION

摘要

A process for producing alpha-amylase resistant starch comprises extruding a feed starch at a temperature in the range of about 60-220~C, thereby produci ng a product alpha-amylase resistant starch. The feed starch can be in the form of an aqueous slurry or paste that has a dry solids concentration of at leas t about 50% by weight. The process optionally can include the additional step of heating the product starch to a temperature of at least about 90~C in the presence of moisture, to increase further the alpha- amylase resistance of t he product.
