Hydrolyzed vegetable protein, or HVP, is produced by boiling cereals or legumes, such as soy, corn, or wheat, in hydrochloric acid and then neutralizing the solution with sodium hydroxide. The acid hydrolyzes, or breaks down, the protein in vegetables into their component amino acids. The resulting brown powder contains, among other amino acids, glutamic acid, which consumers are more familiar with in the form of its sodium salt, monosodium glutamate, or MSG. It is used as a flavor enhancer in many processed foods.

A similar product, from dairy origin, is hydrolyzed whey protein.

Other sources of glutamate, sometimes used in conjunction with HVP, include autolyzed yeast extract and hydrolyzed yeast extract.
