GHATTI GUM Usage And Synthesis

Description

Gum ghatti is an exudate from the tree Anogeissus latifolia, familyCombretaceae, a large tree widely distributed in India and Ceylon.It is a complex, water-soluble polysaccharide composed of thecalcium and magnesium salts of L-arabinose, D-galactose,D-mannose, D-xylose, D-glucuronic acids in the approximate molarratio of 10:6:2:1:2. It is light to dark tan and is insoluble in 90%alcohol.
The tree Anogeissus latifolia, from which gum ghatti is exuded,is also used as a source of timber, and its tannin-rich leaves areused for tanning. It grows extensively in India and Ceylon. Production,collection, and processing methods are very similar tothat for gum karaya. The gum is exuded when the bark is damaged,probably to act as a sealant. It is gathered by hand in the dry seasonby natives whose usual occupation is farming. The largest crop isnormally picked in April. After drying for several days, the gumis transported to Bombay, usually having to be transported throughmountain passes, or ghats, hence the name gum ghatti. In Bombay,the crude gum is sold by auction to exporters, who first have itclassified by hand according to color and purity. In the UnitedStates, the process grinds the tears to a fine particle size. Impuritiesare reduced by sifting and aeration.
Gum ghatti is essentially a calcium salt of ghattic acid, a polysaccharidewith a molecular weight of approximately 12,000. Hydrolysisproducts are L-arabinose (5 moles), D-galactose (3 moles),D-mannose (1 mole), D-xylose (0.5 mole), D-glycuronic acid (1mole), and traces of 6-deoxyhexose. Two aldobiouronic acids,6-0-(P-D-glucopyranosyluronic acid)-D-galactose and 2-0-(|5-dglucopyranosyluronicacid)-D-mannose are obtained on gradedhydrolysis. The gum contains chains of 1,6-lined ji-D-galactopyranoseresidues, to which the aldobiouronic acid units are attached,either directly or through one or more 1,6-linked glactose residues.
Gum ghatti can be dispersed in water to form a colloidal dispersion.Only about 80-90% of the gum is actually soluble. It is quitestable over the pH range 3.5-10.0. It is a natural buffer and smallamounts of acid or alkali will not affect viscosity.
Its properties are usually considered to be similar to gum arabic,but its solutions are more viscous and less adhesive. Use of gumghatti in foods is based primarily on its effectiveness as an emulsifierfor oil and water emulsions. However, solutions of ghatti aremore viscous and less adhesive than those of arabic.

Chemical Properties

Gum ghatti is an exudate from the tree Anogeissus latifolia, a large tree, widely distributed in India and Ceylon The name “ghatti” is derived from the word ghats, meaning “passes,” and given to the gum because of its ancient mountain transportation routes The tree A latifolia is also used as a source of timber, and its tannin-rich leaves are used for tanning Production, collection and processing methods are very similar to those for gum karaya The largest crop is normally picked in April The gum is an exudate from damaged bark, which is gathered by hand during the dry season and sold at auction; tears are ground to a fne particle size by the processor.

Chemical Properties

Colorless to pale-yellow tears, roundedor vermiform. Almost tasteless and odorless, partiallysoluble in water. Can be solubilized by autoclaving.

Physical properties

It is light- to dark-tan and is insoluble in 90% alcohol Gum ghatti is essentially a calcium salt of ghattic acid, a polysaccharide with a molecular weight of approximately 12,000 Structure is a complex water-soluble polysaccharide occurring as a cal.

Uses

Ghatti gum is a plant exudate obtained from the anogeissus latifolia tree. The gum is formed as a protective sealant when the bark is damaged. It forms viscous mixtures in water at concentrations of 5% or greater. Only about 90% of the gum is actually soluble in water and has a ph of 4.5. It has similar uses as gum arabic. It is also termed indian gum. It is used in buttered syrup and as a stabilizer for emulsions.

Uses

As substitute for acacia. As emulsifying agent in pharmaceuticals, oils, waxes.
