Method of Testing
PH : It is measured in 1% soln after stirring for 15 minutes.
Viscosity : In a 500 ml water add 40 gms powder with stirring for 30 minutes. Keep it for 15 minutes then cool down to 30C & measure viscosoty of that paste. ( RV type Viscometer with spindle No. 4 at 2.5 RPM )
Residue content : Take 20 gms of Gum and dissolve into 500 ml & keep for one hour. Filter the above solultion with 200 mesh filter using aspilator or vaccum suction. Wash the filter surface with distilled-water under suction ( wall of filter also to be washed ) Then, dry the filter 50-60 C.
