Gum arabic is a key ingredient in traditional lithography and is used in printing, paint production, glue, cosmetics and various industrial applications, including viscosity control in inks and in textile industries, though less expensive materials compete with it for many of these roles. It is edible, and used primarily in the food industry as a stabilizer, with EU E number E414. It is the original source of the sugars arabinose and ribose, both of which were first discovered and isolated from it, and are named after it. Gum arabic is a complex mixture of glycoproteins and polysaccharides.
Producers harvest the gum commercially from wild trees, mostly in Sudan -80%- and throughout the Sahel, from Senegal to Somalia-though it is historically cultivated in Arabia and West Asia.
In a few cases so‐called "gum arabic" may not even have been collected from Acacia species, but may originate from Combretum, Albizia or some other genus. Originally, gum arabic was collected from Acacia nilotica which was called the "gum arabic tree" in the present day, gum arabic is collected from acacia species, predominantly Acacia senegal and Vachellia -Acacia- seyal the term "gum arabic" does not indicate a particular botanical source. Gum arabic: Gum arabic, also known as acacia gum, arabic gum, gum acacia, acacia, Senegal gum and Indian gum, and by other names, is a natural gum consisting of the hardened sap of various species of the acacia tree. It is also used as a preservative in cured meats and frozen vegetables.It was first synthesized in 1933 by the German chemists Kurt Maurer and Bruno Schiedt. Food and Drug Administration banned the use of sulfites as a preservative in foods intended to be eaten fresh -such as salad bar ingredients-, the use of erythorbic acid as a food preservative has increased. A later study found that erythorbic acid is a potent enhancer of nonheme-iron absorption.Since the U.S.

One such trial investigated the effects of erythorbic acid on vitamin C metabolism in young women no effect on vitamin C uptake or clearance from the body was found. It is denoted by E number E315, and is widely used as an antioxidant in processed foods.Clinical trials have been conducted to investigate aspects of the nutritional value of erythorbic acid. It can also be synthesized from sucrose or by strains of Penicillium that have been selected for this feature. It is synthesized by a reaction between methyl 2-keto-D-gluconate and sodium methoxide. Erythorbic acid: Erythorbic acid -isoascorbic acid, D-araboascorbic acid- is a stereoisomer of ascorbic acid -vitamin C.
