Physico-chemical and rheological properties of any material are important from industrial point of view in order to understand the requirement of different process operations for its value addition as well as for its commercial utilization. The present study describes some of the important physico-chemical and rheological properties of Karaya gum. Efforts have been made to determine moisture content, bulk density, true density, tap density, bulkiness, porosity, Hausner’s ratio, Carr’s compressibility index (%), angle of repose (°), coefficient of friction (n) on glass, mild steel, plywood and rubber surfaces following the established methods for other similar food materials. The lumps of Karaya gum collected from the forest of Chhattisgarh were used in the present study. Both grits and powder samples were used for determination of the properties depending on the demand of the methodology. | Physico-chemical and rheological properties of Karaya Gum (Sterculia urens Roxb.)
