  • Introduction of colloid :
  • Gum arabic is a complex mixture of glycoproteins and polysaccharides. The main uses of Arabic are based upon its properties of emulsification, protective action, adhesiveness, thickening, binding, and stabilization. Its major use is in the food industry to impart viscosity, body and texture to a variety of foods. In addition, it is non-toxic, odorless, colorless, tasteless, and completely water-soluble. It does not affect the flavor, odor of color of foods.Gum arabic is used primarily in the food industry as a stabilizer. It is edible and has E number E414. 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.

    Food

    Also called acacia after the original source, gum arabic is used as an emulsifier and a thickening agent in icing, fillings, chewing gum and other confectionery treats.[1]

    Painting and art

    A selection of gouaches, some containing gum arabic,Gum arabic is used as a binder for watercolor painting because it dissolves easily in water.The addition of a little gum arabic to watercolor pigment and water allows for easier lifting of pigment from paper and thus can be a useful tool when lifting out color when painting in watercolor.[2]

    Ceramics

    Gum arabic has a long history as additives to ceramic glazes. It acts as a binder, helping the glaze adhere to the clay before it is fired, thereby minimising damage by handling during the manufacture of the piece. As a secondary effect, it also acts as a deflocculant, increasing the fluidity of the glaze mixture but also making it more likely to sediment out into a hard cake if not used for a while.

    Photography

    The historical photography process of gum bichromate photography uses gum arabic mixed with ammonium or potassium dichromate and pigment to create a coloured photographic emulsion that becomes relatively insoluble in water upon exposure to ultraviolet light. In the final print, the acacia gum permanently binds the pigments onto the paper.

    Printmaking

    Gum arabic is also used to protect and etch an image in lithographic processes, both from traditional stones and aluminum plates. In lithography, gum by itself may be used to etch very light tones, such as those made with a number five crayon. Phosphoric, nitric or tannic acid is added in varying concentrations to the acacia gum to etch the darker tones up to dark blacks. The etching process creates a gum adsorb layer within the matrix that attracts water, ensuring that the oil based ink does not stick to those areas. Gum is also essential to what is sometimes called paper lithography, printing from an image created by a laser printer or photocopier.

    Pyrotechnics

    Gum arabic is also used as a water-soluble binder in fireworks composition.

    Smoking

    Gum arabic is the most commonly used form of adhesive for rolling papers used in cigarettes.
