Description
Monosodium glutamate (CAS 142-47-2), also known as E621, sodium glutamate, or FEMA 2756, is the sodium salt of glutamic acid, a naturally occurring amino acid. It is produced commercially through bacterial fermentation of carbohydrate sources and carries the EC number 205-538-1.
In food manufacturing, E621 functions as a flavour enhancer by activating umami taste receptors, reducing the need for sodium chloride in processed foods. In personal care formulations, it acts as a humectant and skin conditioner by binding moisture within the stratum corneum, and serves as a buffering agent to stabilise product pH in aqueous systems.
Monosodium glutamate is available in food-grade and cosmetic-grade powder forms, compliant with E621 specifications under EU food regulations, FCC standards, and REACH registration requirements. It is supplied in standard 25 kg bags. Procurement teams should confirm grade suitability against intended application prior to ordering.
