Monosodium glutamate and its relationship to food safety
MetadataShow full item record
Monosodium glutamate (MSG) is one of several forms of glutamic acid found in foods, in large part because glutamic acid (an amino acid) is pervasive in nature. MSG is used in the food industry as a flavor enhancer with an umami taste that intensifies the meaty, savory flavor of food, as naturally occurring glutamate does in foods such as stews and meat soups. Scientific studies have repeatedly indicated that MSG is safe at ordinary levels of consumption for the general population.
