Starch is used as a major component in many food and nonfood applications and determines the overall product properties to a large extent. It is therefore important to understand the effect of processing on starch. Many starch-based products are produced using a thermal as well as a mechanical treatment. Thermomechanical treatment induces various changes in starch, such as disruption of granules, melting of crystallites, and molecular weight reduction.(1) Those changes influence the product properties such as melt viscosity, gelling properties, extrudate swell, and water absorption to a large extent.(2) This article summarizes our recent findings on the influence of thermomechanical treatment on molecular weight reduction of starch with low moisture content (3040%).
