Abstract
There is disclosed a water-soluble polysaccharide composed of rhamnose, fucose, arabinose, xylose, galactose, glucose and uronic acid, and a degree of esterification of uronic acid of not more than 50%. This water-soluble polysaccharide is useful as a protein stabilizer. A process for preparing the same and food containing the same is also disclosed.
Claims5
A process for preparing a water-soluble polysaccharide wherein its constituent sugar components are rhamnose, fucose, arabinose, xylose, galactose, glucose and uronic acid, and having a degree of esterification of uronic acid not more than 50%, comprising demethoxylation of a methylated carboxyl group of uronic acid before or after extraction of a water-soluble hemicellulose, and in which process, said demethoxylation step comprises heating a raw material containing a water-soluble hemicellulose at a temperature of from 40.degree. to 90.degree. C. at a pH of from 9 to 14, and said extraction step comprises heat extracting a raw material containing a water-soluble hemicellulose at a temperature of from 80.degree. to 130.degree. C. at a pH of from 3 to 6 and separating a water-soluble fraction.
