Hidden Names for MSG

The following substances always contain factory created free glutamate, the harmful form found in MSG:



Calcium Glutamate (E623)

Monosodium glutamate

Hydrolyzed Vegetable Protein (HVP)

Textured Protein

Monosopotassium glutamate

Hydrolyzed Plant Protein (HPP)

Yeast Extract

Glutamate (E620)

Autolyzed Plant Protein

Yeast food or nutrient

Glutamic Acid (E620)

Sodium Caseinate

Autolyzed Yeast

Vegetable Protein Extract

Senomyx (Wheat extract labeled as artificial flavor)

Any hydrolyzed protein

Calcium Cascinate

Magnesium glutamate (625)

Monoammonium glutamate (E624)

Soy protein, soy protein concentrate, soy protein isolate

whey protein, whey protein isolate

Natrium glutamate



Anything hydrolyzed or autolyzed

The following substances contain some factory created free glutamate in varying amounts. Please note that some food labels list several of these items, which can add up to a considerable and dangerous amount in one product:

Malted Barley (flavor)

Natural Flavors, Flavors, Flavoring, seasonings

Citric Acid (when processed from corn). Citrate (E330)

Barley malt

“Low” or “No Fat” items

Malt Extract or Flavoring

Smoke flavoring

Dough Conditioners


Soy Sauce

Yeast Nutrient

Caramel flavoring (coloring)

Soy sauce extract

Carrageenan (E407)


Wheat, rice, corn, or oat protein



Gluten and gluten flour or powder


Amino acids (as in Bragg’s liquid amino acids and chelated to vitamins)

Algae,phytoplankton, sea vegetable, wheat/barley grass powders

Protein powders: whey, soy, oat, rice (as in protein bars, shakes, and body building drinks)

Natural Chicken, Beef, or Pork. Flavoring “Seasonings” (Most assume this means salt, pepper, or sices and herbs, which sometimes it is.

Ingredients suspected of containing enough processed glutamate to cause highly sensitive individuals to react:

High fructose corn syrup



Fructose (from corn)

Modified food starch

Reduced fat milk (skim, 1%, 2%)


Caramel color or flavoring

Secithin from soy

Lipolyzed butter fat


Rice syrup

Brown rice syrup

Milk powder - dry milk solids

Whey powder

Gums (guar, vegetable, xantham)

Most low or no fat foods

Anything enriched or vitamin enriched

Corn syrup solids



These substances work synergistically with MSG to enhance flavor.  If they are present, so is MSG.

Protease, protease enzyymes: When seen on label, have been used to break down proteins, Consequently, they create processed free glutamate,  Look for words like “enzyme modified”, “enzymes”, “fermented protein”, “protein fortified”, or fortified anything (milk to shampoos).

Disodium 5’ - guanylate (E627)

Disodium 5’ - inosinate (E631)

Disodium 5’ - ribonucleotides (E635)


Reaction flavors
