The present invention discloses that retrograded starch having more than 55% resistant starch with &gt;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.

Highly fermentable resistant starch

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.

Method for the production of isomalto-oligosaccharide rich syrups

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.

Process for the production of 2-keto-D-glusonic acid

A method is disclosed for producing a pentitol. 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.

Process for the production of arabinitol

The present invention discloses a chemical method for producing meso-erythritol. The method comprises catalytic hydrogenation of tartaric acid. The tetritol mixture resulting from the hydrogenation can be separated into its components. Alternatively selected components can be isomerized prior to such a separation.

Method for production of tetritols, specifically meso-erythritol

An immune-stimulatory or tumor treatment agent, optionally in a pharmaceutically acceptable carrier or diluent, comprises extracellular .beta.-glucan produced by Glomerella cingulata CMI CC 330957 or by mutants or variants thereof.
