谷氨酸钠 (CAS No.16177-21-2)
- 物化性质
- 白色结晶粉末或无色晶体，无气味。熔点232℃（熔化时分解）。易溶于水，20℃时溶解度约74g/100mL；水溶液呈微酸性。在200℃以上长时间加热可脱水生成焦谷氨酸钠，失去鲜味但无害；在强碱性环境中可生成谷氨酸二钠。
- 技术参数
- 含量（以干基计）≥99.0% 外观为白色结晶或结晶性粉末，无气味 熔点232℃，熔化时伴随分解 20℃时水溶解度约74g/100mL 包装为25kg/袋
English description（英文原文，共 1208 字符）
Product Name:Monosodium glutamate
English Name:Monosodium glutamate
CAS No.:16177-21-2
Aliases:Sodium glutamate, MSG, L-Glutamic acid monosodium salt
Molecular Formula:C5H8NNaO4
Physical Properties:White crystalline powder or colorless crystals, odorless. Melting point 232 °C (decomposes on melting). Freely soluble in water, with a solubility of about 74 g/100 mL at 20 °C; aqueous solution is slightly acidic. When heated above 200 °C for a prolonged period, it dehydrates to form sodium pyroglutamate, which is harmless but has no umami taste. Under strongly alkaline conditions, it can form disodium glutamate.
Uses:Used as a food umami flavor enhancer, widely applied in Chinese cuisine, soups, sauces, broths, meat, poultry and fish products. It enhances the overall flavor of foods, acts synergistically with other umami substances such as nucleotides, and can partially replace salt in low-sodium formulations to improve the taste of reduced-salt foods.
Technical Specifications:
Assay (dry basis) ≥ 99.0%
Appearance: white crystalline powder or crystals, odorless
Melting point: 232 °C (decomposes on melting)
Solubility in water at 20 °C: approximately 74 g/100 mL
Packaging: 25 kg/bag
