Abstract
Guar gum (GG) from seeds of cluster bean (Cyamopsis tetragonolobus) contains mainly non-ionic galactomannan polysaccharide. Due to fascinating properties, great natural abundancy, low cost, biocompatibility and biodegradability, natural GG polysaccharide has been studied and employed in various research fields and industries. To explore and extend full potentials of GG, further chemical functionalization of the material is essential. This review highlights recent progress in the chemical modification of GG and its derivatives based on nucleophilic reactions, partial oxidation, graft polymerization and cross-linking with diverse chemical reagents and reaction pathways. Moreover, further insights into structure–property relationships as well as potential applications of the materials are also provided and discussed.
