Abstract: The present invention relates to a process for the production of xylitol. Specifically the process comprises two reaction steps. The first step is the fermentative conversion of a hexose to a pentitol. The second step is the catalytic chemical isomerisation of the pentitol to xylitol. Optionally, the xylitol is separated from the other pentitols.

Abstract: The invention relates to a friction vacuum pump (1) with a stator (3) and a rotor (4), which form at least two pump stages (12, 13, 14) with one gas inlet (23, 28) each, as well as with junction for the pump stages, which are equipped with junction openings (36,37) and serve for the connection of the gas inlets (23, 28) of the pump stages with devices to be evacuated; in order to avoid high conductance losses it is proposed that the junction openings (36, 37) are located in a plane which is disposed laterally adjacent to the pump stages (12, 13, 14) such that the distance between the junction openings (36, 37) and the rotor axis (15) is of minimum feasible size.

Abstract: The present invention discloses an isotonic beverage product for direct increase of the muscular ATP level consisting essentially of a solution of D-ribose and blood glucose increasing monosaccharides and oligosaccharides and/or hydrogenated glucose syrups. These drinks serve to increase the overall performance during physical exercise and at the same time diminish fatigue.

Abstract: The present invention discloses that retrograded starch having more than 55% resistant starch with >50% chains of DP 10-35 gives rise to a significantly higher amount of n-butyrate production under conditions simulating the human colon. It is expected that such an increased n-butyrate production will diminish the development of colon diseases notably of colon cancer.

Abstract: The present invention describes a method for the production of isomalto-oligosaccharides syrups. The method comprises the use of enzymes immobilized on a re-usable carrier. The carrier is preferably an anion exchanger. The enzymes used for the conversion of starch hydrolysates are transglucosidase and pullulanase preferably these enzymes are co-immobilized. The carrier/enzyme conjugate is further reinforced by cross-linking.

Abstract: This process for the production of 2-keto-D-gluconic acid starts from D-glucose. D-glucose is catalytically oxidised using molecular oxygen in a one-pot process. The oxidation is performed in the presence of well-known Pt/Pb catalysts. The initial reaction to D-gluconic acid is performed at constant pH between 7 and 10. There after the reaction is continued without pH control. This process results in a high selectivity compared with known processes.

The disclosed method more particularly relates to producing arabinitol from hexoses, e.g. galactose and/or glucose, and/or fructose, or lactose hydrolysate, or invert sugar, or starch hydrolysates. The hexose is oxidatively decarboxylated to a C.sub.5 -aldonic acid which is thereafter catalytically hydrogenated to obtain the desired arabinitol.

Abstract: A sealing system for a roller bearing having an inner bearing race on the axle, bearing rollers around the inner race and an outer race around the bearing rollers. A sealing cap is spaced axially away from one axial end of the races. A first sealing ring is sealed to the outer race, and it includes an axial area that extends toward and that is spaced a short distance from the sealing cap defining a first sealing gap. A felt ring is disposed within the bore defined by the axially extending area of the first sealing ring. The felt ring is spaced axially out from the rollers and defines a first grease holding chamber between the rollers and the felt ring and a second grease holding chamber axially outward of the felt ring. A second sealing ring is located axially outward of the felt ring. It includes a sealing lip which seals at the felt ring.
