Molecular characterisation and functional properties of gum arabic
… to isolate several molecular mass components of gum arabic. The u. v. (218 nm) gpc elution profile showed the presence of several prominent peaks; however, only one major peak (FAw 3.8 x 10-9 g moll) and a minor peak (FAw 1.45 x 106 g mol-1) were observed in thedifferential refractive index (R. …

Viscosity modification of gum arabic as a means of enhancing marketability
Metal ions of gum arabic were removed by ion exchange to yield the free acid form. Arabate salts were prepared using monovalent and divalent metal ions. Addition of monovalent metal ions was found to double the viscosity of the gum as compared to the viscosity of the raw gum, and more than triple …

The chemistry of acacia gums
Gummy material is often exuded in response to injury by trees belonging to the Rosaceae and Leguminosae families. Acacia trees belong to the Leguminosae family, and the exudate from a variety of acacia species is known as "gum arabic" or "gum acacia". Gum arabic is collected for industrial use from …

Improving Adhesion of Seasonings to Crackers with Hydrocolloid Solutions
… The hydrocolloids that were used include gellan gum, kappa-carrageenan, methyl cellulose, gum karaya, gum tragacanth, gum arabic, guar gum, modified starch, and maltodextrin. Solutions of similar hydrophobicity to the powder gave the greatest adhesion. NaCl, barbecue (BBQ), ranch, and sour cream …

Of disciples and sultans: Power, authority and society in the nineteenth century Mauritanian Gebla
… at least the eighteenth century, a class of Arabic-speaking warriors had exercised political hegemony in the Gebla, collecting tribute from nomadic pastoralists and sedentary cultivators, and levying tolls upon the European trade in gum arabic.

Grewia polysaccharide gum as a pharmaceutical excipient
Grewia gum is obtained from the inner stem bark of the edible plant Grewia mollis Juss (Fam. Tiliaceae) which grows widely in the middle belt region of Nigeria, and is also cultivated. The dried and pulverised inner stem bark is used as a thickening agent in some food delicacies in that region of …

Micro-fading spectrometry: an ivestigation into display of traditional watercolour pigment in anoxia
… of a traditional Prussian blue pigment ground in gum Arabic was investigated for the first time in 0%, 2%, 3.5%, 5%, 10% or 21% oxygen concentrations. Results from this investigation indicated that the previously reported deleterious effects of reduced oxygen concentrations (hypoxia) for Prussian …

Production of polyhydroxyalkanoate copolymers from plant oil
… In one of these methods, the glycoprotein gum arabic was used to emulsify the plant oil. This emulsification reduced the lag phase in oil cultures and allowed representative samples to be taken early in experiments. High density palm oil fermentations were also carried out using …
