Foam Fraction and Fractions Physico-chemical Characterization of the Gum from Acacia seyal var. Seyal

Abstract

This research was performed to investigate the physicochemical properties of foam and residues fractions of gum talha (Acacia seyal var.seyal). The results showed that a foam fraction has moisture (7.65%) and residual has (6.23%). While residual fraction has Protein (1.75%) and Nitrogen content (0.28%) and foam has (1.925%) and (0.308%) respectively. Ash content was founded in residues (2.89%) and in foams (2.64%). K (0.090%), Ca (0.978%), Na (0.008%), and Mg (0.352%) were founded in residues and in foam were founded (0.068),(0.849%),(0.008) and (0.312%) respectively, Cr is founded in foam (2.29*10-4) and founded in residues is (5.74*10-5), Zn and Pb were not detected in both of which. Optical rotation and Viscosity were found in residues (+51) and (3.611) and in foam were found (+47) and (2.94) respectively. Foam fraction has pH (5.04) while residual has pH (4.33). Sugars such as; Rhamnose, Arabinose and Galactose were founded in foams (0.21865%), (2.2440 %) and (1.90245%) while residual has (0.1464%), (1.8664%) and (1.4715%) respectively.
