CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Monosodium glutamate appears as white or off-white crystalline powder with a slight peptone-like odor. pH (0.2% solution)7.0. (NTP, 1992) |
|---|---|
| Color/Form | White free flowing crystals or crystalline powder |
| Odor | Practically odorless |
| Taste | Meaty taste comes from contaminants in crude glutamates; sweet-saline taste in large concn; no flavor in small quantity |
| Boiling Point | 225 °C (decomposes) |
| Melting Point | 450 °F (Decomposes) (NTP, 1992) |
| Solubility | greater than or equal to 100 mg/mL at 68 °F (NTP, 1992) |
| Density | 26.2 (saturated water solution at 20 °C) |
| Optical Rotation | [α]D/20 between + 24,8° and + 25,3°; (10 % solution (anhydrous basis) in 2N HCl, 200 mm tube) |
| Decomposition | When heated to decomposition it emits toxic fumes of oxides of /nitrogen and sodium oxide/. |
| pH | Between 6,7 and 7,2 (5 % solution) |
| Other Experimental Properties | THE MONOHYDRATE FORMS NEEDLES |
| Chemical Classes | Nitrogen Compounds -> Other Nitrogen Compounds |
