The colour varies from whitish yellow to amber depending on factors like the proximity of the tear to the bark, the length of time it has remained on the tree before being picked and the age of the product in storage.
Gum Ghatti: Colony Gums
The molecules may have an overall rod shape in solution. It is then ghafti sorted according to color and impurities into various grades before being exported to the United States. It is used at about 0. Ghatti modifies the refractive index of table syrup until the syrup becomes clear. The tree is the source of Indian gum, also known as ghatti gum, which is used for calico printing among other uses.
Emulsifier Anogeissus latifolia is a species of small to medium-sized tree native to the India, Nepal, Myanmar, and Sri Lanka. It also prevents fluid loss at elevated temperature.
Gum Ghatti — Vikaspedia
Viscosity is a function of pH. Its leaves contain large amounts of tannin, and are used in India for tanning.
It occurs in nature as a mixed calcium, magnesium, potassium and sodium salt. Used in powdered explosives to improve resistance to water damage. A Carrageenan gel will start losing some of its strength at pH below 4—5 and above Identification of Anogeissus latifolia Wallich and analysis of refined gum ghatti. Microwave-generated bionanocomposites for solubility and dissolution enhancement of poorly water-soluble drug glipizide: Gum Ghatti will not form a true gel. Industrial Powdered Ghatti is used in ammonium nitratesemigelatin mixtures, and powdered explosives to improve their resistance to water damage.
Viscosity increases sharply with pH upto a maximum at about pH 8 and above that the solutions tend to become stringy. Number 1 grade is off-white to buff; number 2 grade is light amber to brown, and number 3 grade is dark brown. Gum Ghatti is a moderately viscous gum lying intermediate between Arabic and Karaya.
The guum are non-Newtonian, as is true of most water-soluble gums, and their viscosity increases geometrically with concentration. Crude Ghatti has between 0. As a binder in long-fibered light weight papers. Novel interpenetrating polymer matrix network microparticles for intestinal drug delivery.
The exudates are hand picked gumm the locals, mostly tribal and laid to dry in the sun for several days. The leaves are also fed on by the Antheraea paphia moth which produces the tassar silk Tussaha form of wild silk of commercial importance.
They are easily preserved with a mixture of a maximum of 0. The lightest color has the least impurities and the greatest effectiveness in most applications.
Following are some of the applications of Gum Ghatti: Gum Ghatti prevents fluid loss in oil well drilling muds when used at low concentrations in neutral mixtures, and in high salt concentration. The tree occurs throughout the greater part of India; more commonly in the dry deciduous forests. The gum is similar to other hydrocolloids that are subject to bacterial attack.

Our final product for export is either in lump form or powder where the gum is sized to mesh or finer. Dry films are relatively soluble and brittle.
Foods Ghatti stabilizes butter-containing table syrups. Potential Blenders and core components note. Ghatti dispersions are not affected by small amounts of acid or alkali since the gum acts as a buffer and reverts to its normal pH of about 4.
Properties Physical Gum Ghatti is almost odorless and has a bland taste. As an emulsifier and stabilizer in beverages and gkm containing table syrups. Sifting, aspiration and density-table separation are used during this powdering to remove impurities.
The crude gum has a glossy fracture and occurs in rounded tears, which are normally less than 1 cm. Glycerin and propylene glycol may also be used.
