Abstract:
A process for the preparation of a dextrose in powder form having:a dextrose content at least equal to 99%, an &agr; crystalline form content at least equal to 95%, a water content at most equal to 1%, a compressibility, determined according to test A, at least equal to 80 N, said test A consisting in measuring the strength, expressed in Newton, which is necessary to cause a tablet prepared from said dextrose to be crushed, this strength thus reflecting the resistance to crushing of said tablet, which is cylindrical with convex sides (radius of curvature 14 mm), having a diameter of 13 mm, a thickness of 6 mm and a weight of 0.764 g, i.e. an apparent density of 1.3 g/ml, the said strength being exerted against the peripheral surface of the tablet in the direction of the axis of revolution thereofby means of a mechanical movable stop applied against the said surface along a generatrix, the said tablet being furthermore immobilized against the mechanical stationary stop also applied against the peripheral surface of the tablet along a generatrix, the latter being diametrically opposed to the generatrix against which the mechanical movable stop is applied, the process comprising the steps of: granulation of a dextrose powder essentially in the alpha crystalline form using a binder; and ageing by drying the granulated dextrose thus obtained.
