Abstract: Coating colors having a dextrin having high amylopectin content. When such a dextrin is used in the form of an adhesive, it confers an excellent stability on the adhesive. When the adhesive is subsequently incorporated in the coating color, it makes it possible to adjust the Brookfield viscosity thereof, while providing a good compromise between water retention and rheological behavior at high shear gradient. Also, the use of such dextrin for the manufacture of a coating color. Further, a process for the manufacture of a paper or of a cardboard coated on at least one its face with a coating color, and papers and cardboards thus obtained.

Abstract: A method for cooking a starchy composition, includes: (a) a first step of 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 the 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° C. and 180° C.

Abstract: An adhesive composition includes an aqueous dispersion having a primary part, consisting essentially of a gelatinized starch, and a secondary part, comprising essentially a non-gelatinized starch and/or a swollen starch, wherein the starch of the secondary part is a native legume starch, and the starch of the primary part is optionally a native or modified legume starch, the legume starches having an amylose content ranging between 30 and 52%. The invention also concerns the method for preparing such a composition, comprising its use, assembling the parts and drying and satisfying the requirements of modern fast machinery.
