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.

Claim (Index 1):
A method of stimulating immune response in a mammal, comprising administering to a mammal in need of stimulation of its immune response a product selected from a food product, a beverage, a dietary food product, a clinical food product and a dietary supplement, the product comprising an aqueous sugar beet extract that is enriched in polysaccharide having a backbone comprising alternating rhamnogalacturonan-I cores and alpha(1,4)-linked polygalacturonic acid or alpha(1,4)-linked oligogalacturonic acid cores,\n wherein the molar ratio of galacturonyl acid residues to rhamnosyl residues in the backbone of the polysaccharide ranges from 2.5:1 to 1:1, wherein the rhamnogalacturonan-I core comprises one or more side chains substituted at the 4-OH position of the rhamnosyl residues and having a backbone of at least one or more alpha(1,5)-linked arabinosyl residues, wherein the rhamnogalacturonan-I core comprises one or more side chains substituted at the 4-QH position of the rhamnosyl residues and having a backbone of at least one or more beta(1,4)-linked galactosyl residues, and wherein the molar ratio of arabinosyl residues to rhamnosyl residues is between 50:1 and 1.1:2.
