Gum Arabic is a gum formed from the sap of Acacia trees, which grow in Sudan and throughout the African Sahel, stretching from Senegal to Somalia. Acacia senegal (the Gum Arabic or Gum Acacia tree) produces the highest qrade of Gum Arabic, known as Kordofan or Hashab and primarily comes from Senegal. Acacia seyal (also known as Vachellia seyal or the Red Acacia tree) produces a grade called Talha gum that mainly comes from Sudan. Incisions are made in the bark to encourage the production of the viscous exudate, which is tapped and hardens in the air and sunlight to form tear-shaped lumps.


Gum Arabic is sold in the form of lumps or a food and pharmaceutical grade powder. It is edible, but tasteless and odourless, and performs an encapsulation and suspension function for flavours. The gum also has film-forming and adhesive properties, functioning as a binder and gelling agent. It is a natural hydrocolloid, forming a gel in the presence of water, but is fully water-soluble, forming a clear, viscous solution that is weakly acidic (pH of around 4.5). Gum Arabic comes in two grades that have different chemical compositions: Senegal grade is used as an emulsifier, mainly in beverage emulsions, while Seyal grade is used in confectionery, coatings and as a soluble dietary fibre.


Food Industry

Gum Arabic is used as a food additive in sauces and dressings, functioning as an emulsifier, stabiliser and thickening agent. In dry packaged goods such as soups, instant drinks and dessert mixes, Gum Arabic improves dispersion when added to a liquid and helps to encapsulate and protect flavours, extending shelf-life. In baking, it is used in icing, fillings and edible glitter for cakes. In beverages, Gum Arabic acts as an emulsifier and stabiliser of oil-water emulsions, a thickener in dairy products, and a clouding agent in other liquids. It is also a foam stabiliser in carbonated soft drinks and a clarifying agent in the production of alcoholic beverages such as wine and beer, as well as acting as a texture improver in winemaking.

Confectionery Industry

Gum Arabic is used as an ingredient in chocolate candies, gumdrops, marshmallows and chewing gum. It functions as a glazing agent to coat chocolate products thanks to its film forming ability, and also acts as a barrier coating to separate sugar and fat. Gum Arabic helps to retard crystallisation in high sucrose confections and emulsifies oils and fats used as flavourings. In addition, it is used as a flavour carrier, imparting a clean, long-lasting fresh taste in chewing gum. In soft, chewy candies, Gum Arabic enables the product to be chewed for a longer period without sticking to the teeth. It is used in higher concentrations in reduced calorie soft candies. Gum Arabic is also used in anti-cariogenic (anti-tooth decay) candies since it is resistant to degradation by micro-organisms in the mouth.

Pharmaceutical & Healthcare Industry

Gum Arabic is used as a dietary supplement, including high fibre powders and drinks, and may have some prebiotic properties. It is also an ingredient in cough syrups and is used as an excipient coating for tablets and capsules. In addition, it may promote wound healing and act as a demulcent, relieving inflammation or irritation of the mucous membranes in the mouth by forming a protective film and reducing dental plaque.

Incense Industry

Gum Arabic is used as a binding agent in incense.

Textile & Leather Industry

Gum Arabic is used to coat textiles and as an ingredient in leather shoe polish.

Printing & Packaging Industries

In the Printing industry, Gum Arabic is used in lithography for both traditional stones and aluminium plates. The positive part of the image is etched using an oil-based (hydrophobic or water-repelling) substance, while the negative image remains water-retaining (hydrophilic). When a solution of Gum Arabic in water is applied to the plate, the gum sticks to the non-oily surface, ensuring that the oil-based ink only adheres to the positive image. Gum Arabic also acts as a viscosity control in inks and is used in paint production. In addition, it forms an edible glue used as an adhesive for postage stamps, envelopes and cigarette papers.

Other Industries

In the Photography industry, Gum Arabic is used to create a coloured photographic emulsion that becomes relatively insoluble in water after exposure to ultraviolet light. The gum also helps bind the pigments to the paper.

In the Art industry, Gum Arabic is used in watercolour paint as it helps bind the pigment to the paper surface. The gum in the paint film acts as a glaze, increasing luminosity, preventing the colours from lightening and the paint from bleeding beyond the brush stroke. It also allows more working time by slowing water evaporation.

In the Ceramics industry, Gum Arabic is used as a binder in ceramic glazes, helping the glaze adhere to the clay prior to firing. It also increases the fluidity of the glaze mixture. On firing, the gum burns out at a low temperature, leaving no residue in the glaze.

In the Pyrotechnics industry, Gum Arabic is used a binder in fireworks.

Zoo keepers feed Gum Arabic (e.g. two parts water or fruit juice to one part gum) to primates like marmosets and bush babies kept in captivity as a substitute for the tree gum they would naturally consume in the wild. Squirrel monkeys and tamarins are also believed to enjoy the taste. Gum Arabic is a source of energy, calcium and other minerals, as well as being used as a means of enriching their lives.

In the Personal Care industry, Gum Arabic is used as a binder, emulsifier and suspending (viscosity increasing) agent in face-masks, skin creams, hair creams and other lotions.
