A method for the reactive extrusion of an amylaceous substance in the presence of a polyphosphate serving as a cross-linking agent, to the resulting products, and to the uses thereof. In particular, a method for the reactive extrusion of starch in the presence of a cross-linking agent which is a polyphosphate, in particular sodium trimetaphosphate, which behaves like an effective substitute for glyoxal. The method makes it possible to manage the competition between the destructuring and cross-linking mechanisms of the amylaceous substance. The crystalline phase content of the cross-linked starches is thus controlled in accordance with the specific needs of the final use. |
