Physicochemical Properties of Acacia Polyacantha Gum.

Abstract

Although there are more than 1100 species of Acacia distributed throughout the tropical and subtropical areas of the world, most commercial gum arabic is derived from Acacia senegal locally known as hashab gum (in the Sudan) and as Kordofan gum around the world. Gum arabic has been known for many thousands of years and there are no artificial substitutes that match it for quality or cost of the production.1 Gum arabic consists mainly of high-molecular weight polysaccharides made up of rhamnose, arabinose, and galactose, glucuronic and 4-O-methylglucuronic acid, and the salts of calcium, magnesium, potassium, and sodium of the two acids.

A comparative Analytical Studies onAcaciapolyacantha gum Samples collected from three different locations in Sudan

“…Layoon samples are in the range of (10.2 to 10.5 ml/g) (Table3).Analysis of variance within location showed insignificant difference (p≤ 0.05) in each; also location was found to be insignificantly affecting the intrinsic viscosity of all samples was (10.3 ml/g). The intrinsic viscosity of Acacia polyacantha gum was closer to the result obtained by Siddig(2003) for Acacia polyacantha gum (12.7ml/g), and less than (14ml/g) for Acacia seyal reported by Elkhatim(2001), it was also in a close agreement with the recent results(10.2ml/g) reported by Elnour(2007).…”

“…However the effect of location on equivalent weight showed insignificant differences ( Table 4), and the mean value of equivalent weight of samples in the three locations were (1348.68). This value is in agreement with that range(1136.0 to 1875) for Acacia senegal gum reported by Karamalla(1998), it was also greater than the recent studies of Acacia polyacantha gum(1280.80) represented by Elnour(2007).…”

“…The mean value of ash content of samples from the three different locations was( 2.9%). The range of ash content of Acacia polyacantha gum was closer to the result mentioned by Elkhatim(2001) forpolyacantha gum (2.8%), and also is in agreement with the mean value(2.9)reported by Abdelsalam(1998).This result is less than that (3.3%) for Acacia polyacantha gum reported by Elnour(2007). Table 1 showed the nitrogen content of Abugarin samples, which ranged from( 0.32 to 0.40 %) and hence the protein content ranged from(2.11 to 2.44 %).…”

Active Fractions of Methanol Crude Obtained from Acacia seyal gum: Antioxidant Capacity, using FTIR Analysis

“…Chemically, GA is a complex mixture of macromolecules of different sizes and composition -mainly carbohydrates and proteins. It is rich in non-viscous soluble fibers with high dietary value, and also contains minerals like potassium, magnesium, and calcium (Ali et al, 2013a;Elnour, 2007). Gum arabic antioxidant properties, nephroprotectant, and other effects have been highlighted in recent studies (Ali et al, 2013b).…”

Physicochemical Properties of Kakamut Gum (<i>Acacia polyacantha</i>) and Hashab Gum (<i>Acacia senegal</i>): A Comparative Analysis

“…It has intricate bark and double echinoderms. The bark is yellow and has brown peels with black knots at the base of the leaves [6]. The length of the leaves is approximately 25 cm.…”
