About
Hydrolyzed vegetable protein (HVP) is produced by acidic, alkaline, or enzymatic hydrolysis of vegetable proteins (such as soy, wheat, or corn), yielding a mixture of amino acids, peptides, and proteins. It is widely used as a savory flavor enhancer in soups, seasonings, snack foods, sauces, and processed foods due to its high free-glutamate content.
Safety summary
The primary safety concern with acid-hydrolyzed HVP is the potential formation of 3-monochloropropane-1,2-diol (3-MCPD), a processing contaminant considered possibly genotoxic and carcinogenic, which is subject to regulatory limits in multiple jurisdictions. HVP contains free glutamate comparable to MSG and may trigger adverse reactions in glutamate-sensitive individuals, while people with soy, wheat, or corn allergies face meaningful allergenic risk depending on the protein source. No specific ADI has been established for HVP itself; regulatory concern centers on contaminant limits, allergen labeling obligations, and source-plant disclosure.
Regulatory landscape
| Jurisdiction | Status | Note |
|---|---|---|
| EFSA (European Food Safety Authority) (European Union) | Approved | HVP from conventional plant sources (e.g., soy, pea) is not considered a novel food under Regulation (EU) 2015/2283, as acid hydrolysis of proteins is an established food processing technique with a documented history of widespread use in soups and convenience foods. Treated as a conventional food ingredient rather than a regulated food additive; no E-number assigned. Products derived from allergenic sources listed in Annex II of Regulation (EU) 1169/2011 must carry allergen labeling.source |
| FSSAI (Food Safety and Standards Authority of India) (India) | Approved | Permitted as an ingredient in seasonings under FSS (Food Products Standards and Food Additives) Regulations, 2011, Section 2.9.31 (Seasoning). The FSS (Contaminants, Toxins and Residues) Regulations, 2011 set a 5 mg/kg tin contaminant limit for hydrolyzed protein products. No specific maximum use level established; governed by GMP.source |
| FDA (Food and Drug Administration) (United States) | Approved | 21 CFR 102.22 specifically requires that the common or usual name of each hydrolyzed protein on food labels identify the plant source (e.g., 'hydrolyzed soy protein'), distinguishing it from MSG which must be labeled separately.source |
