FORMULA: C5 H8 NNa O4 H2O or HOOC CH(NH2)-CH2 CH2 COONa H2O
MOLECULAR MASS: 180.13
ALTERNATIVE FORMS: Monoammonium glutamate/ Potassium glutamate/ Monopotassium glutamate/ Ammonium glutamate
PROPERTIES AND APPEARANCE: Monosodium salt of L-form of glutamic acid. White or almost-white crystals or powder; free-flowing
cystals or crystalline powder; forms rhombic prisms when crystallised from water. Below -8°C will
recrystallise as a pentahydrate which after filtration and exposure to air will lose water of
crystallisation and become the monohydrate. Slight peptone-like odour; meat-like taste. Very soluble in
water; slightly soluble in alcohol.
PURITY %: Not less than 99.0% of C 5H8NNaO4 H2O
SOLUBILITY % AT VARIOUS TEMPERATURE/pH COMBINATIONS:
in water: @ 25°C 74.2 g/100 ml @ 60°C 101.4 g/100 ml
FUNCTION IN FOODS: Flavour enhancer; dietary supplement (Japan)
ALTERNATIVES: Disodium inosinate; disodium guanylate; monoammonium glutamate; monopotassium glutamate;
L-glutamic acid; ammonium glutamate; potassium glutamate
