Abstract

The invention relates to a method for cooking a starchy composition, comprising: (a) a first step comprising mixing at least one starch powder with an aqueous starch fluid, wherein the ratio of the mixture of the starch powder to the aqueous starch fluid is such that the total starch content of the mixture obtained is greater than 45% by weight, and wherein said first step is carried out in a cooking chamber maintained at a temperature at least equal to the highest gelatinization temperature (GT) of all the starches present in the mixture, for a period of time sufficient to obtain a colloidal solution of starch, and (b) a second step comprising heating the colloidal solution of starch obtained in step (a), at a pressure greater than atmospheric pressure and at a temperature of between 120 DEG C and 180 DEG C.

Description

technical field

[0001] The present invention relates to a continuous or discontinuous process for cooking starchy raw materials having a high dry matter content, the resulting starch composition and its use, in particular as a binder. Background technique

[0002] The object of the present invention is to propose a relatively simple and inexpensive cooking method that allows the cooking of liquid starch aqueous compositions with a high dry matter content. The process makes it possible to obtain an aqueous starch solution, substantially free of granular starch, while having a high dry matter content greater than 35% by weight and preferably less than 75% by weight, and having sufficient Low viscosity and good storage stability, in other words, the cooled starch composition does not show any retrogradation (gelatinization caused by recombination of amylose macromolecules).
