Product Application of L-Glutamic Acid CAS#56-86-0
Food Industry:
As a key component of umami enhancers (such as those converted into sodium glutamate), L-Glutamic acid helps improve food flavor. It is also used in food preservation, texture enhancement, and as a nutritional fortifier in infant foods and health products.
Medical Field:
In pharmaceuticals, it is used in the preparation of drugs for the treatment of hepatic encephalopathy, neurasthenia, and other conditions. It can also serve as a component of compound amino acid infusions to help supplement essential amino acids for the human body.
