Monosodium glutamate (MSG), also known as sodium glutamate, is the sodium salt of glutamic acid. MSG is found naturally in some foods including tomatoes and cheese. MSG is used in cooking as a flavour enhancer with an umami taste that intensifies the meaty, savoury flavour of food, as naturally occurring glutamate does in foods such as stews and meat soups.

MSG is commonly used and found in stock cubes (Bouillon cube), soups, ramen, gravy, stews, condiments, savoury snacks etc.
