What is Monosodium Glutamate?


Monosodium glutamate is a popular flavor enhancer derived from L-glutamic acid, a naturally occurring amino acid that’s necessary for the creation of proteins. Aside from being used as a food additive, MSG occurs naturally in certain foods, including tomatoes and cheeses.

MSG boosts the flavor of foods by stimulating taste receptors and has been shown in research studies to increase the acceptance of particular flavors. Here are some foods that commonly contain MSG:

- Fast food
- Chips and snack foods
- Seasoning blends
- Frozen meals
- Canned soups and soup mixes
- Processed meats
- Mayonnaise, ketchup, barbecue sauce, and soy sauce
- Instant noodle products
