<p>Crystalline maltitol compsn. having a porous, honeycombed structure, a maltitol content of 92% or more and an apparent density of 100-700 g/l is new. Also claimed is the prepn. of a crystalline maltitol compsn. comprising: (i) prepn. of a maltitol syrup with a dry matter content of at least 50% and a maltitol content of at least 92 %; (ii) finely spraying this syrup onto a fluidised bed of powdered crystalline maltitol at 60-110 degrees C, the wt. of the bed being at least twice that of the syrup and its maltitol content being at least equal to that of the syrup; (iii) drying the bed in order to obtain the desired compsn.; (iv) opt. maturing the compsn. to achieve the required level of crystallinity and pref. an enthalpy of fusion of≥130 J/g; and (v) opt. partially recycling the crystalline compsn. to constitute a new bed. The compsn. has an enthalpy of fusion of > 130 (pref. > 155) J/g and pref. contains≥95 (pref. 99) % maltitol, less than 0.5% water, less than 5 (pref. less than 2) % dry wt. polyols other than maltitol and additives selected from sweeteners, colourings, flavours, perfumes, vitamins, minerals, pharmaceutical or veterinary active ingredients, fatty acid esters, organic and inorganic acids and their salts, proteins, amino acids, and enzymes.</p> |
