Abstract
A method for producing a heat-modified starch, comprising the steps of: (i) preparing a starch milk having a solids content of between 20% and 45% by weight and adding an alkaline agent, so as to obtain a final conductivity of between 4 and 7 mS/cm (ii) filtering the starch milk so as to recover a starch cake; (iii) introducing the starch cake, continuously, into a dryer at the same time as a continuous stream of hot air in order to recover a dried powder; (iv) continuously supplying a turboreactor with the dried powder, and by setting parameters for the speed of rotation of the stirrer, so that the dried powder is continuously centrifuged and conveyed into the turboreactor; (v) recovering the heat-modified starch produced.
