Milk Protein Concentrate

About

What it is and where it shows up.

Milk protein concentrate (MPC) is a dairy ingredient produced from skim milk by ultrafiltration, removing lactose and minerals while retaining both casein and whey proteins, typically containing 40–90% protein on a dry-weight basis. It is used in food manufacturing as a protein source, emulsifier, stabilizer, texturizer, and foaming agent in products such as beverages, nutrition bars, infant formula, cheese, and sports nutrition products.

Safety summary

The regulatory and scientific consensus.

MPC is broadly regarded as safe for healthy adults; it carries no ADI restriction, no IARC carcinogenicity classification, and no known toxicity at normal dietary intakes. The primary safety consideration is its status as a major food allergen (milk), requiring mandatory allergen labelling under FDA, EU, FSSAI, and Codex rules. Individuals with cow's milk protein allergy (CMPA) or severe lactose intolerance (residual lactose may be present in lower-protein grades) must avoid it; no concerns exist for the general adult population at typical food-use levels.

Regulatory landscape

What food-safety regulators have decided.

Jurisdiction	Status	Note
EFSA (European Food Safety Authority) (European Union)	Approved	Intact cow's milk protein (including MPC) is an approved protein source in follow-on formulae and general foods under Regulation (EU) 2016/127. Use in infant formula and follow-on formula is governed by Delegated Regulation (EU) 2016/127 (applicable from 22 February 2021); each protein hydrolysate form requires individual EFSA safety evaluation. MPC as an intact protein ingredient in conventional foods is permitted under general food law (Regulation (EC) No 178/2002).source
FSSAI (Food Safety and Standards Authority of India) (India)	Approved	Milk protein concentrates are classified as milk derivatives and recognized milk products under FSSAI Food Products Standards and Food Additives Regulations, 2011 (as amended). Mandatory Milk Logo labelling applies. Permitted in infant complementary foods under FSS (Infant Nutrition) Regulations, 2020 (Version II, 2024).source
FDA (Food and Drug Administration) (United States)	Approved	Earlier GRAS Notice GRN 000504 covers milk protein concentrate (MPC) and milk protein isolate (MPI); Leprino GRN 000633 incorporates GRN 000504 safety data by reference.source

Who should approach with care

Whose guidance would steer them away.

Other — Individuals with cow's milk protein allergy (CMPA) must avoid MPC entirely, as it is a major food allergen under FDA (FD&C Act §403(w)) and EU/FSSAI allergen labelling regulations and can trigger IgE-mediated anaphylaxis.

Lactose Intolerance — Lower-protein-grade MPCs (e.g., MPC40–MPC60) retain residual lactose that may provoke gastrointestinal symptoms in lactose-intolerant individuals; high-grade MPCs (MPC80+) have substantially reduced lactose and are generally better tolerated.

Infants — Use of MPC-based protein in infant formula is subject to case-by-case EFSA safety and suitability evaluation under Regulation (EU) 2016/127 and FSSAI Infant Nutrition Regulations; caregivers should consult a paediatrician before selecting formula products based on concentrated milk proteins.

Kidney Disease — MPC is a high-protein, phosphorus-rich ingredient; patients with chronic kidney disease (CKD) who are on protein- or phosphorus-restricted diets should consult their nephrologist before consuming MPC-fortified products.
