CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Gum arabic is a white powder. (NTP, 1992) |
|---|---|
| Color/Form | Spheroidal tears up to 32 mm in diameter; also flakes and powder |
| Odor | SOLN OF GOOD GRADES ARE PRACTICALLY ODORLESS |
| Taste | SOLN OF GOOD GRADES ARE PRACTICALLY TASTELESS |
| Solubility | 50 to 100 mg/mL at 64 °F (NTP, 1992) |
| Density | 1.35 to 1.45 (NTP, 1992) |
| Stability/Shelf Life | EMULSIONS PREPD WITH ACACIA ARE STABLE OVER WIDE PH RANGE |
| Optical Rotation | Soln of gum from Acacia verek are levorotatory; other Acacia species are dextrorotatory |
| Viscosity | VISCOSITIES OF GUM ARABIC SOLN ARE RELATIVELY LOW WITH A VISCOSITY OF 200 CPS HAVING BEEN REPORTED FOR 30% SOLN; MAX VISCOSITY IS ATTAINED @ PH 6-7 WITH ONLY GRADUAL CHANGE OVER PH RANGE 5-10; VISCOSITY INCR GRADUALLY AS CONCN IS INCR UP TO 20-25%, @ WHICH POINT MORE MARKED INCR TAKES PLACE; VISCOSITY OF GUM ARABIC SOLN DECR WITH TEMP |
| pH | Aq soln acid to litmus |
| Other Experimental Properties | MIXED WITH TWICE ITS WT IN WATER IT DISSOLVES SLOWLY FORMING A VISCOUS LIQ WHICH IS VERY STICKY |
| Chemical Classes | Biological Agents -> Vegetable Gums |
