Abstract: The invention provides a method of producing a hydrolysed pectic polysaccharide isolate that is enriched in rhamnogalacturonan-I, said method comprising the steps of: providing a pectin-rich substrate that has been obtained from plant material without the use of organic solvent, said pectin-rich substrate containing at least 3% by weight of dry matter of pectic polysaccharides; subjecting the pectin-rich substrate to enzymatic treatment to partially hydrolyse the pectic polysaccharides, said treatment enzymatic treatment comprising the use of one or more pectinases selected from pectin lyase (EC4.2.2.10), pectate lyase (EC 4.2.2.2), rhamnogalacturonan galacturonohydrolase (EC 3.2.1.173), endo-polygalacturonase (EC 3.2.1.15), exopolygalacturonase (EC 3.2.1.67 and EC 3.2.1.82); subjecting the partially hydrolysed pectic polysaccharides to ultrafiltration using an ultrafiltration membrane having a molecular weight cut-off in the range of 5 to 100 kDa; and recovering the ultrafiltration retentate.

Abstract: The invention relates to a prebiotic composition for use in a method of therapeutic or prophylactic treatment of disorders associated with disturbed composition or functionality of the intestinal microbiome in a subject, said use comprising oral administration of the prebiotic composition to the subject, wherein the composition contains at least 0.1% by weight of dry matter of RG-I polysaccharides originating from fruit, carrot, pea, chicory or sugar beet, said RG-I polysaccharides having a molecular weight in excess of 15 kDa and having a backbone consisting of galacturonic acid residues and rhamnose residues, said rhamnose residues being contained in alpha(1?4)-galacturonic-alpha(1?2)-rhamnose residues, wherein the molar ratio of galacturonic acid residues to rhamnose residues in the RG-I polysaccharides is within the range of 20:1 to 1:1.

Abstract: The invention relates to a product for use in the therapeutic or prophylactic treatment of infections, said treatment comprising oral administration of the product, wherein the product is selected from a nutritional formulation, a food product, a dietary supplement, a beverage and a pharmaceutical product, said product containing carrot RG-I polysaccharides having the following combination features: a molecular weight in the range 10-300 kDa; a backbone consisting of galacturonic acid residues and rhamnose residues, said rhamnose residues being contained in alpha(1?4)-galacturonic-alpha(1?2)-rhamnose residues; the following monosaccharide composition: 20-60 mol. % galacturonic acid residues, wherein the individual galacturonic acids can be methylated and/or acetyl-esterified; 8-50 mol. % rhamnose residues; 0-40 mol. % arabinose residues; 0-40 mol.

Abstract: The invention relates to a composition for use in the prevention or treatment of Salmonellosis in animals, said use comprising administering the composition to the animal, wherein the composition contains at least 0.01% by weight of dry matter of rhamnogalacturonan I (RG-I) polysaccharides having a molecular weight of more than 2 kDa and having a backbone consisting of galacturonic acid residues and rhamnose residues, said rhamnose residues being contained in alpha(1?4)-galacturonic-alpha(1?2)-rhamnose residues, wherein the molar ratio of galacturonic acid residues to rhamnose residues in the RG-I polysaccharides is within the range of 50:1 to 1:1. The use of RG-I polysaccharides in the treatment or prevention of Salmonellosis provides an alternative for the widespread use of antibiotics. Furthermore, these RG-I polysaccharides may be used to prevent or treat Salmonellosis caused by Salmonella strains with resistance to antibiotics.

Abstract: Objective of the present invention is to provide polysaccharides which modulate immune response, and which can be used as ingredients in edible products or pharmaceutical compositions. The present invention provides such polysaccharides obtained from the species Camellia sinensis, which comprise a rhamnogalacturonan-I core, and wherein the molar ratio of galacturonyl acid residues to rhamnosyl residues in the backbone of the polysaccharide is close to 1:1. The present invention also provides edible products or pharmaceutical compositions containing such polysaccharides, in order to modulate immune response.
