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.
