| Taste: | Meaty taste comes from contaminants in crude glutamates; sweet-saline taste in large concn; no flavor in small quantity|A 1% concn or more is liable to produce a sweetish taste. | Experimental Properties: | THE MONOHYDRATE FORMS NEEDLES|THE FLAVOR BECOMES PERCEPTIBLE @ A CONCN OF 0.03% IN DISTILLED WATER|Below -8 deg /C/, it crystallizes as a pentahydrate, which, after filtration and exposure to air, loses water of crystallization and becomes the monohydrate. |
| Air and Water Reactions: | Water soluble. | Reactive Group: | Salts, Acidic |
| Reactivity Profile: | Acidic salts, such as MONOSODIUM GLUTAMATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH’s of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions. |
