| 摘要 |
The present invention relates to a crosslinking composition to be used for crosslinking heterogeneous polysaccharides, the composition comprising a crosslinking agent selected from a group of crosslinking polysaccharides containing at least two carboxylic acid functionalities in its backbone and/or side chains, wherein the crosslinking polysaccharides are different from the heterogeneous polysaccharides, and the composition further comprises a crosslinking catalyst selected from the group consisting of organic acids, amino acids, acidic inorganic salts and mixtures thereof, in the amount of 0.1-100 weight parts calculated on 100 weight parts of the crosslinking polysaccharide. Further, the invention relates to crosslinked heterogeneous polysaccharides and a method of crosslinking heterogeneous polysaccharides. |
