Main Functions: 
L-glutamic acid is widely used. As drugs, it can treat hepatic coma, also can be used for production of MSG, food additives, spices, cosmetics, and used in biochemical researches. 
1. Food Industry 
Amino acids as important nutrients of human growth, not only has special physiological functions, but also has unique features in food industry. L-Glutamic acid can be used as a flavor enhancer, enhancing beverage and food taste. It not only can enhance the flavor of food, but also has animal food preservative effect. 
2. Cosmetics industry 
L-Glutamic acid as a nutritional drugs can be used for skin care and hair care. For hair agent, it can be absorbed by hair scalp to prevent hair loss; When applied to the skin, it has effective treatment on wrinkles . 
L-Glutamic acid is a natural plant ingredient, from the world's most advanced biological enzyme engineering technology, to develop daily used cosmetics such as hair care and skin care cosmetics. So surface active agent to synthesize L-Glutamic acid has great market. 
3. Pharmaceutical Industry 

L-Glutamic acid can be used as carbon and nitrogen nutrition with body metabolism. It has high nutrient value. 

After absorbed by the body, L-Glutamic acid easily formulate glutamyl ammonia with blood ammonia to relieve ammonia toxicity in the metabolic process, thus to prevent and cure hepatic coma. It is adjuvant drugs for patients with liver diseases. 
There are many patent medicines made from L-Glutamic acid, such as medicinal oral tablets of glutamic acid, sodium glutamate ( potassium) injection, calcium glutamate injection, acetyl glutamate injection etc. 


With the progress of science & further researches, new fields 
of L-Glutamic acid application will be more and more wide!
