The present invention relates to microcrystallized polyol comprising at least two polyols, wherein said polyols are selected from the group consisting of maltitol, xylitol and lactitol and wherein said composition contains at least 35% by weight of each of at least two of said polyols microcrystallized together into a solid microcrystalline product. The present invention also relates to a process for the microcrystallization of polyols into a polyol composition. The microcrystallized polyol composition can be used in confectionery, foodstuffs, oral hygiene products and pharmaceuticals and in dietetic products.

Crystallization of polyol compositions, crystalline polyol composition product and use thereof

The present invention relates to a microcrystallized polyol comprising at least two polyols, wherein said polyols are selected from the group consisting of maltitol, xylitol and lactitol and wherein said composition contains at least 25% by weight of each of at least two of said polyols microcrystallized together into a solid microcrystalline product. The present invention also relates to a process for the microcrystallization of polyols into a polyol composition. The microcrystallized polyol composition can be used in confectionery, foodstuffs, oral hygiene products and pharmaceuticals and in dietetic products.

The invention relates to novel anhydrous (&#x3b2;) lactitol crystals, belonging to the orthorhombic P222cystal system and having unit cell constants a=9.6 &#x212b;, b=11.1 &#x212b;, c=14.0 &#x212b;. The invention also relates to crystalline lactitol products containing the novel anhydrous &#x3b2; lactitol and to a process for the preparation thereof by crystallizing from an aqueous solution of lactitol. The novel anhydrous &#x3b2; lactitol is stable and nonhygroskopic and it may be used as a substitute for sugar in foodstuffs and sweets, in as well as in pharmaceutical and hygienic products.

Anhydrous lactitol crystals, a product containing the same and a process for the preparation thereof as well as use thereof

The invention relates to a novel process for the crystallization of xylitol by contacting a xylitol solution with particulate xylitol suspended in a gas, drying the material to produce a multitude of microrystals and conditioning the material into an agglomerated product. The invention also relates to a particulate crystalline xylitol product having novel properties, to the use thereof in confectionery, foodstuff pharmaceuticals and oral hygiene products, and to special products comprising the same.

Process for the crystallization of xylitol

The invention relates to a method of crystallizing maltitol from a maltitol solution by supersaturating the solution in repsect of maltitol and crystallizing the maltitol from the solution. In the process of the invention, the maltitol-containing solution is brought to a supersaturated state, and the solution is subjected to evaporation, until a crystallization mass is obtained which has a crystal yield of 1 to 80% on maltitol, and a dry solids content of over 50%. After bringing the solution to a supersaturated state, the solution is preferably seeded by adding maltitol seed crystals. In one embodiment of the invention, additional feed liquid is added during the crystallization by evaporation.

Method of crystallizing maltitol

The present invention relates to a novel process for the crystallization of lactitol, to a particulate crystalline lactitol product having novel properties, to the use thereof as in foodstuffs, pharmaceuticals and oral hygiene products, as well as to special lactitol sweeteners. The process comprises: contacting a liquid containing dissolved lactitol with gas suspended fine solid particles containing microcrystalline lactitol; causing substantial removal of the solvent component of said liquid and allowing the resulting lactitol material to form an essentially solid composition of matter comprising a multitude of microcrystals of lactitol; and causing said lactitol composition to be conditioned during a further step to provide a product consisting essentially throughtout its entire structure of a multitude of microcrystals of lactitol agglomerated together in a random manner. The invention provides a crystalline lactitol product consisting essentially throughout its entire structure of a multitude of microcrystals of lactitol agglomerated together in a random manner.

Crystallization of lactitol, crystalline lactitol product and use thereof

The invention relates to a method for producing xylitol from a material containing xylose and xylonic acid. According to the method, xylose and xylonic acid are separated from the material containing xylose and xylonic acid, whereafter the separated xylose and xylonic acid are reduced to xylitol, and the xylitol is recovered.
