The invention relates to methods of thermomechanical degradation of starch, which allow the use of starch that has not been subjected to any pretreatment. By controlling the conditions of the thermomechanical degradation, different starch extrudates can be obtained. For example, low-viscosity extruded starch (LVES) and thermoreversible gelling extruded starch (TRES) may be obtained by subjecting native granular starch and water to thermomechanical degradation. The optional addition of a starch-modifying agent leads to modified extruded starch (MOES). The invention also relates, inter alia, to compositions obtainable by the methods of the invention; products comprising said compositions; and various applications of said compositions.

A method for preparing a highly branched starch of different crystal forms by using a glycogen branching enzyme. The method comprises: (1) dispersing starch in a buffer to obtain starch milk; (2) performing a sub-gelatinization pretreatment on the starch milk, and then adding a glycogen branching enzyme for enzymolysis; and (3) after the enzymolysis is completed, performing ethanol precipitation, washing, freeze-drying, grinding and sieving to obtain branched starch. By means of omitting the conventional modification step of high-temperature pre-gelatinization followed by cooling and enzyme addition, the glycogen branching enzyme is directly added at 60°C to process granular starch with different crystal form structures, which maintains the intact granular morphology of the starch, thereby achieving the effects of simultaneous enzymolysis and starch granule swelling.
