Abstract
The invention relates to a method for producing a heat-modified starch, comprising the steps consisting in: (i) preparing a starch milk having a solids content of between 30 and 40%, preferably between 35 and 37% by weight, (ii) adding a solution of an alkaline agent at a weight concentration of between 25 and 35%, preferably of 30%, so as to obtain a conductivity on the milk of between 4 and 7 mS/cm, (iii) ensuring a contact time of between 0.5 and 2 hours, (iv) filtering and drying the starch milk such that the 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, even more preferentially between 15 and 35 minutes.
