Hydrolysed Vegetable Protein

About

What it is and where it shows up.

Hydrolysed vegetable protein (HVP) is a flavouring/seasoning ingredient produced by acid or enzymatic hydrolysis of plant proteins (typically soy, corn, wheat, or pea), breaking them down into free amino acids and short peptides. It imparts a rich savoury (umami) taste and is widely used in soups, sauces, seasonings, snack foods, instant noodles, and processed meats.

Safety summary

The regulatory and scientific consensus.

The primary safety concern with acid-produced HVP is contamination by 3-monochloropropane-1,2-diol (3-MCPD), a processing contaminant classified by IARC as Group 2B (possibly carcinogenic to humans), for which JECFA established a provisional maximum tolerable daily intake (PMTDI) of 2 µg/kg body weight/day. HVP sourced from wheat or soy may trigger allergic reactions in sensitised individuals, and those proteins must be declared on the label. The high free-glutamate and sodium content of HVP may also pose concerns for MSG-sensitive individuals and those with hypertension or kidney disease.

Regulatory landscape

What food-safety regulators have decided.

Jurisdiction	Status	Note
EFSA (European Food Safety Authority) (European Union)	Approved	HVP is permitted as a food ingredient and flavouring in the EU; no E-number assigned as it is not classified as a regulated food additive. Commission Regulation (EC) No 1881/2006 on contaminants in foodstuffs sets a maximum level of 20 µg/kg for 3-MCPD (expressed at 40% dry matter) in acid-hydrolysed vegetable proteins and soy sauce, to control carcinogenic contaminant formation from acid hydrolysis. Pea and soy protein hydrolysates confirmed as non-novel foods per Regulation (EU) 2015/2283.source
FSSAI (Food Safety and Standards Authority of India) (India)	Approved	Recognised under FSS (Food Products Standards and Food Additives) Regulations, 2011 as a permitted ingredient in noodles, cereal-based products, complementary foods, and special dietary uses. FSS (Contaminants, Toxins and Residues) Regulations, 2011 (Version VIII, 2025) set a maximum tin (Sn) limit of 5.0 mg/kg for the food category encompassing canned fish, canned meats, meat extracts, and hydrolysed protein.source
FDA (Food and Drug Administration) (United States)	Approved	Listed in the FDA EAFUS (Everything Added to Food in the United States) database as an approved food substance used for flavouring and technical effects. Must be declared by its specific common name on food labels per 21 CFR 101.22; no specific maximum use level — applied at GMP levels. No single CAS number assigned as HVP is a complex mixture.source

Who should approach with care

Whose guidance would steer them away.

Infants — Infants have the highest weight-adjusted exposure to 3-MCPD relative to the JECFA PMTDI of 2 µg/kg bw/day, an immature detoxification capacity, and FSSAI and EU regulations more stringently restrict contaminants in infant food categories.

Children — Children's higher food intake relative to body weight results in disproportionately elevated 3-MCPD exposure compared to adults, potentially approaching or exceeding the established PMTDI with regular consumption of HVP-containing products.

Gluten Intolerance — HVP derived from wheat contains residual gluten peptides and is unsafe for individuals with coeliac disease or non-coeliac gluten sensitivity; the source protein must be verified from the product label.

Other — Individuals with soy or corn allergies should avoid HVP sourced from those plants, as residual allergenic proteins may persist through hydrolysis; source ingredient must be declared on the label under FDA (21 CFR 101.22) and FSSAI labelling rules.

— HVP is inherently high in sodium from its use as a savoury seasoning, which can worsen elevated blood pressure in hypertensive individuals; regular consumption should be limited.
