STANDARD TESTING SPECIFICATION
Name of the Product: Guar Gum U.S.P. / N.F.
| No. | Tests | Specifications (U.S.P. 38 / N.F. 33) |
|---|---|---|
| 1. | Identification | A. Under a microscope in glycerol, it shows pyriform or ovoid cells, usually isolated, having very thick walls around a central somewhat elongated lumen with granular contents, and smaller polyhedral cells, isolated or in clusters with thinner walls. B. A stiff gel forms with 2 gm guar in 45 ml of water. C. Gel forms with suspension of 0.1 gm in 10 ml of water with 1 ml of a 10 g/L solution of disodium tetraborate D. The Chromatogram obtained with the test solution shows 2 zones due to galactose and mannose. |
