General description

Gum arabic from acacia tree is extracted from the branches of Acacia senegal and Acacia seyal trees. It is an edible dried gummy exudate. Gum Arabic has high solubility and is used in food industry as a stabilizer, emulsifier, flavouring agent, thickener and surface-finishing agent. It initiates turbidity or hinders sugar crystallization. Gum arabic inhibits color pigmentation and protein precipitation in wine production.

Application

Gum arabic from acacia tree has been used:
  • as an emulsifying agent to determine lipase activity in shrimps
  • for the visualization of mossy fiber sprouting
  • as an immunogen and for coating microtitre wells in plate-trapped antigen ELISAs (PTA-ELISAs)
  • for silver enhancement for immunohistochemistry
  • as a component for Timm′s staining solution
  • in nitrocellulose-based soil adhesion assay
  • to separate few-layer graphene (FLG) from bulk graphite layers

Other Notes

Believed to be a branched polymer of galactose, rhamnose, arabinose, and glucuronic acid as the calcium, magnesium, and potassium salts with a mol. wt. of approx. 250,000.

  5. Can Product G9752, Gum arabic from acacia tree, be used to extract nuclei from ciliate cells?

    This product has been cited for use in a lysis buffer to extract nuclei from ciliate cells.  The reference is J. Eukaryotic Microbiology, 43(3), 198-202 (1996).

  6. Can you provide a description of the polysaccharide in Gum arabic from acacia tree, Product G9752?

    The polysaccharide in gum arabic is branched with a main chain of (1->3) linked β-D-galactopyranosyl units, with side chains of (1->3) β-D-galactopyranosyl units joined to it by (1->6) links. The side chains are two to five units in length. Both main chains and side chains have attached units of α-L-arabinofuranosyl, α-L-rhamnopyranosyl, β-D-glucuronopyranosyl and 4-O-methyl-β-D-glucuronopyranosyl units.

  7. What is the solubility of Product G9752, Gum arabic from acacia tree?

    According to the chemicals encyclopedia published by the Royal Society of Chemistry, 12th ed., Entry# 11, gum arabic is insoluble in alcohols. It is almost completely soluble in twice its weight of water. It is soluble in glycerol and in propylene glycol, but prolonged heating may be necessary for complete solution.
