  • Patent number: 6821547
    Abstract: The present invention is directed to a process and product by process for preparing a carbohydrate polymer which comprises polymerizing a sugar at a temperature below the point of substantial decomposition thereof and under reduced pressure in the presence of a catalytic effective amount of an organic acid selected from the group consisting of a monocarboxylic acid, a lactone of a monocarboxylic acid and arylol, while removing water formed during said polymerization, said organic acid being non-volatile and having only one acidic functionality and having no amino groups thereon.

  • Publication number: 20040151815
    Abstract: The invention relates to a product based on a sugar beet extract, which is useful as a flavor improver in ingestible products, particularly in foodstuffs, especially in beverages sweetened with other than natural sugar. The invention also relates to a process for preparing said product starting from various streams of the beet sugar manufacturing process. The process of the invention is based on membrane techniques and/or chromatographic fractionation. The invention also relates to the use of said product as a flavor improver in ingestible products. Furthermore, ingestible products including said product are covered by the invention. The invention also relates to a method of improving the flavor of ingestible products by adding said product to the ingestible product.

  • Patent number: 6395893
    Abstract: 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.
