Crystalline maltitol composition and method for production
A non-seeded method for making crystalline maltitol is described. The method includes evaporating liquid maltitol to a moisture content of between about 4.5 percent to about 6.0 percent to produce a maltitol feed; cooling said maltitol feed with water at a temperature of between about 10 degrees to about 20 degrees Celsius; and extruding said maltitol feed without using a nozzle. The process is performed without a seeding step. A crystalline maltitol composition having at least 45% by volume maltitol crystals having a size of at least 50 microns made by the method is also described.
