What are flavor enhancers?
Flavor enhancers are food additives that intensify or modify the existing taste of food without contributing a distinct flavor of their own. The most widely recognized flavor enhancer is monosodium glutamate (MSG), which activates umami taste receptors to create a savory, meaty depth of flavor. Other common flavor enhancers include disodium inosinate, disodium guanylate, hydrolyzed vegetable protein, and autolyzed yeast extract. The NOVA food classification system identifies flavor enhancers as characteristic of ultra-processed foods, as these compounds are widely used in processed food manufacturing to boost palatability and create complex taste profiles through industrial additives rather than whole food ingredients.
6,183 products in our database contain flavor enhancers. 4,477 of them (72%) are Level 4, the most processed of our four levels.
Which foods contain flavor enhancers?
Flavor enhancers are prevalent in savory snack chips, instant noodles and ramen, canned soups, frozen dinners, seasoning blends, soy sauce, bouillon cubes, processed meats, ranch dressing, fast food items, gravy mixes, flavored crackers, and most categories of savory convenience foods.

Flavor Enhancers can appear in ingredient lists under several names. If you see any of the following, this is the ingredient family you are looking at:
Function
Flavor enhancers amplify the perception of existing flavors in food, particularly savory and umami tastes, allowing manufacturers to create more intensely flavored products or achieve desired flavor intensity with fewer expensive ingredients. MSG and nucleotide enhancers work synergistically — when combined, their flavor-boosting effect is multiplied several-fold beyond what either achieves alone. This synergy allows very small amounts to produce significant taste impact, making them cost-effective tools in food product development.
Sources
MSG is produced commercially through bacterial fermentation of sugars derived from corn, sugarcane, or tapioca starch, yielding the amino acid glutamate which is then crystallized with sodium. Disodium inosinate and disodium guanylate are nucleotides produced through fermentation or extracted from yeast and meat sources. Hydrolyzed vegetable protein is made by breaking down soy, corn, or wheat protein with acid or enzymes to release free amino acids. Autolyzed yeast extract is produced by allowing yeast cells to break down their own proteins through enzymatic action.
Health considerations
MSG is classified as GRAS by the FDA, and major international regulatory bodies have affirmed its approved status at typical dietary levels. The concept of "Chinese Restaurant Syndrome" attributed to MSG has not been consistently reproduced in controlled scientific studies. Some individuals report sensitivity to MSG, though double-blind studies have produced inconsistent results on this topic. Hydrolyzed proteins and yeast extracts contribute sodium to the diet.
This information is for educational purposes only and does not constitute medical advice.
Regulatory
MSG must be declared by name on ingredient labels when added as a direct ingredient. However, ingredients that naturally contain free glutamate — such as hydrolyzed proteins, autolyzed yeast extract, and tomato paste — do not need to declare MSG content even though they provide the same compound. The FDA prohibits the use of the term "No MSG" or "No Added MSG" on products that contain ingredients with naturally occurring free glutamate. The EU assigns E-numbers to flavor enhancers (E620-E640).
