1. A method for producing a heat-modified starch, comprising the steps of:
(i) preparing a starch milk having a solids content of between 30 and 40% by weight,
(ii) adding a solution of an alkaline agent at a weight concentration of between 25 and 35%, so as to obtain a conductivity on the milk of between 4 and 7 mS/cm,
(iii) ensuring a contact time of the starch milk with the alkaline agent of between 0.5 and 2 hours,
(iv) filtering and drying the starch milk such that a conductivity of the dried starch resuspended at 20% by weight of solids is between 0.7 and 2.5 mS/cm,
(v) heating said dried starch so as to bring it to a temperature of more than 180° C. for a residence time of between 10 and 40 minutes.
