L-Glutamic Acid is a non-essential amino acid and the most abundant excitatory neurotransmitter in the vertebrate nervous system. It is naturally found in high concentrations in tomatoes, cheese, mushrooms, and fermented foods. It contributes to their characteristic umami taste.
In the food industry, L-Glutamic Acid and its sodium salt (MSG) are among the most widely used flavor enhancers globally. It is produced on an industrial scale through microbial fermentation using sugar-based feedstocks. Beyond flavoring, L-Glutamic Acid serves as a key building block for the synthesis of other amino acids and bioactive compounds including glutathione and GABA.
