Crystalline mixture solid composition and process for preparation thereof

Abstract

A crystalline mixture solid composition which has almost no hygroscopicity, is easy to handle and dissolve and hardly worn by abrasion, and comprises α-D-glucopyranosyl-1,1-mannitol and α-D-glucopyranosyl-1,6-sorbitol and may further comprise α-D-glucopyranosyl-1,1-sorbitol in a certain case is obtained in an extremely short period of time by a power-saving and labor-saving process with a small-scale apparatus. A composition which comprises 20 to 75 wt % of α-D-glucopyranosyl-1,1-mannitol, 23 to 70 wt % of α-D-glucopyranosyl-1,6-sorbitol and 2 to 25 wt % of α-D-glucopyranosyl-1,1-sorbitol and is in a crystalline mixture solid state or has a specific surface area of 0.07 to 0.1 m2/g, and a composition which comprises 30 to 75 wt % of α-D-glucopyranosyl-l,1-mannitol, 25 to 70 wt % of α-D-glucopyranosyl-1,6-sorbitol and has a specific surface area of 0.07 to 0.1 m2/g. The above compositions are produced by a process comprising supplying a raw material, which is obtained by optionally removing trehalulose from a mixture containing isomaltulose and trehalulose produced from cane sugar through an isomerization reaction and hydrogenating into a kneader having a thin and long cooling zone together with seed crystals and discharging the obtained composition from an outlet continuously.
