Characteristics and composition of Albizia procera (Roxb.) Benth gum

The monosaccharide composition and physicochemical properties of Albizia procera gum was investigated. The crude exudate gum was reddish brown in color yielding a clear solution in water. The flow property of powdered and dried gum was established through Carr's index and angle of repose. It was observed that the gum possesses a fairly good flow property. Total carbohydrates, ash, protein and moisture contents were determined to show its purity. Rheology of 5% solution of the gum was studied in Brookfield viscometer. FTIR spectrum was recorded and DSC analysis was also performed. Scanning electron microscopy was performed to study the morphology of the gum. Monosaccharide constituents were separated and analyzed by High performance anion exchange chromatography-PAD system with gold electrodes after acid hydrolysis. It was found that arabinose and galactose were the main monosaccharides present in the exudate gum. (C) 2012 Elsevier B.V. All rights reserved.
