Hydrolyzed vegetable protein aHVP is not allergenic, since proteins are degraded to single amino acids which are not likely to trigger an allergic reaction. A recent study has shown that aHVP does not contain detectable traces of proteins or IgE-reactive peptides. This provides strong evidence that aHVP is very unlikely to trigger an allergic reaction to people who are intolerant or allergic to soy or wheat. Hydrolyzed vegetable protein Hydrolyzed vegetable protein (HVP) products are foodstuffs obtained by protein hydrolysis and are used as ingredients with an authentic bouillon (broth) taste. Regarding the production process, a distinction can be made between acid-hydrolyzed vegetable
