1.OCCURS IN NATURE as a mixed calcium, magnesium, potassium & sodium salt.
2.Composed of larabinose, D-galactose, D-mannose, D-xylose & D glucoronic acid in a molar ratio of 10;6;2;1;2 plus traces less than 1% of 6-deoxyhexose
3.Bland taste & no odour
4.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.
5.Forms viscous solution at concentrations of about 5% or higher.
6.Exhibits typical non-Newtonian behaviour
7.Moderately viscous gum lying intermediate between Arabic & karaya.
8.Viscosity profile gives it a unique status in the spectrum of hydrocolloids.
9.Excellent emulsifying properties.
10.Normal pH of the dispersion is 4.8
11.Viscosity increases with pH upto a maximum at about pH
12.Easily preserved with a mixture of a maximum of 0.17% methyl & 0.03% propyl o hydroxybenzoate as well as with glycerin and propylene glycol.
13.Benzoic acid,sodium acid as well as sodium benzoate at 0.1% concentration are effective preservatives.
