Gum Ghatti

Gum Ghatti

Gum Ghatti (also known as Indian gum) is a complex water-soluble polysaccharide; Gum Ghatti is an amorphous, translucent exudate of the Anogeissus Latifolia tree of the Combretaceae family. The tree is quite large and is found abundantly in the dry, deciduous forests of India. The gum has a glassy fracture and frequently occurs in rounded tears, which are normally less than 1 cm in diameter, but it more often occurs in larger vermiform masses.

Process:

Strict standards for color and impurities has been set on every batch purchased by KACHABO GUMS. The bark is removed and sand or silica is sorted out by sifting, aspiration, and density-table separation. This is to insure the cleanest possible gum.

Physical Property:

Ghatti has a bland taste and practically no order. Only about 90% of the gum disperse in water, and this portion forms a colloidal dispersion.

Viscosity:

Gum Ghatti forms a viscous dispersion when mixed with water to 5% concentration or greater. Changes in viscosity with concentration are indicated in Table 1.

The normal pH of the usually slightly straw-colored solution is 4.8 changes in viscosity with pH are shown in Table 2, indicating that a maximum viscosity is obtained at pH~8.

  • Does not dissolve in water to give a clear solution but rather over 90% of the gum disperses in water to form a colloidal dispersion
  • Forms viscous solutions at concentrations of about 5% or higher
  • Exhibits typical non-Newtonian behavior
  • Moderately viscous gum lying intermediate between Arabic and Karaya
  • Viscosity profile gives it a unique status in the spectrum of hydrocolloids
  • Excellent emulsifying properties
  • Normal pH of the dispersion is 4.8
  • Viscosity increases with pH up to a maximum at about pH
  • Easily preserved with a mixture of a maximum of 0.17% methyl and 0.03% propyl o hydroxybenzoate as well as with glycerin and propylene glycol
  • Benzoic acid, sodium acid as well as sodium benzoate at 0.1% concentration are effective preservatives

Applications of this gum are:

  • As an emulsifier and stabilizer in beverages and butter containing table syrups
  • Flavor fixative for specific applications
  • Preparation of powdered, stable, oil-soluble vitamins
  • Emulsifier of petroleum and non petroleum waxes to form liquid and wax paste emulsions
  • Used in combination with polyacrylamide to aid in the polymerization and formation of uniform and discrete prills of cross-linked polystrene
  • Used in powdered explosives to improve resistance to water damage

Ghatti gum is available in various grades that suit different applications that varies in terms of color, solubility, viscosity, BFOM and total ash content.
