Product Overview

Acid Casein — EU Bulk Dairy Protein Supplier

Acid casein is the principal protein fraction of bovine milk, precipitated by acidification to the isoelectric point (pH ≈ 4.6). It is an off-white powder with a protein content typically exceeding 88% on a dry basis (N×6.38), making it one of the most concentrated dairy protein raw materials available. FDCM supplies food-grade acid casein from EU stock in quantities from 25 kg, with no framework contracts required.

Acid casein finds broad application across food manufacturing, nutraceuticals, adhesives and technical industries. In food applications it is valued for its water-binding, emulsifying and gelling properties, as well as its slow-digestion profile relevant to protein supplement formulations. Each batch ships with a Certificate of Analysis (CoA) covering protein, moisture, fat, ash and pH.

As a B2B wholesale supplier operating across all 27 EU member states, FDCM offers fast dispatch via DSV road freight, competitive per-kg pricing for volumes from 25 kg to full container loads, and complete documentation for quality-managed production environments — including allergen declarations and non-GMO statements on request.

Industry Applications

Where Acid Casein Is Used

From processed cheese to sports nutrition and industrial adhesives — acid casein is a versatile high-protein ingredient across food, technical and nutraceutical sectors.

🧀

Processed Cheese & Analogues

Primary functional protein in processed cheese production. Provides cohesiveness, meltability and sliceability. Used in analogue cheese formulations as partial or full casein source, controlling fat encapsulation and texture.

💪

Sports Nutrition & Supplements

Slow-release protein profile (micellar structure intact at neutral pH) makes acid casein suitable for nighttime protein formulations and sustained-release supplement blends. Used in protein powders, RTD shakes and functional food bars.

🍞

Bakery & Functional Foods

Improves water retention, crumb structure and protein enrichment in bread, pasta and meat analogues. Used as a protein fortifier in high-protein bakery lines and sports biscuits.

🏭

Technical & Industrial Applications

Used in adhesives, paper coatings, and plastic composites where protein-based binding is required. Industrial-grade casein applications (paints, glues, fibre production) historically represent significant global consumption.

🥛

Dairy Ingredient Blending

Base ingredient for sodium caseinate and calcium caseinate production. Reacted with alkalis to produce soluble caseinate forms used in coffee whiteners, infant formula and protein beverages.

🔬

R&D & Nutraceuticals

Used in research applications exploring protein digestibility (PDCAAS/DIAAS), bioactive peptide release (casomorphins, ACE-inhibitory peptides) and controlled protein matrix studies in functional food development.

Regulatory Compliance

EU Food Law & Documentation

EU Dairy Regulation

Acid casein produced for human consumption is regulated under Regulation (EC) No 853/2004 of the European Parliament and of the Council, laying down specific hygiene rules for food of animal origin. Dairy establishments producing casein are required to hold EU approval numbers.

For labelling purposes, acid casein is not classified as a food additive under Regulation (EC) No 1333/2008 — it is a food ingredient. It is, however, a major allergen (milk) under Regulation (EU) No 1169/2011 and must be declared accordingly in product labelling.

Documentation Available

Every shipment includes a Certificate of Analysis (CoA) specific to the production batch, covering protein, moisture, fat, ash, lactose and pH parameters. Additional documentation — Technical Data Sheet (TDS), Safety Data Sheet (SDS), allergen declaration, non-GMO statement and country of origin certificate — is available on request at no additional charge.

Halal and Kosher certificates can be provided for eligible batches on request. Please specify documentation requirements at time of order.

FAQ

Frequently Asked Questions

The minimum order quantity is 25 kg — one standard paper bag. There are no framework contracts, registration fees or lengthy onboarding procedures. Business customers can create a free account on FDCM.eu and place an order directly. Larger volumes such as full pallets (500 kg) or container loads are available with adjusted pricing on request.

Acid casein is the raw, insoluble form of casein protein precipitated at its isoelectric point (pH ~4.6). It is largely insoluble in water at neutral pH. Sodium caseinate is produced by reacting acid casein with sodium hydroxide, making it water-soluble. For applications requiring water solubility — such as protein beverages, coffee creamers or emulsified systems — sodium caseinate is typically preferred. For technical applications, processed cheese or cost-sensitive protein enrichment, acid casein is the standard choice.

Every shipment includes a Certificate of Analysis (CoA) specific to the production batch, covering protein, moisture, fat, ash and pH. Technical Data Sheet (TDS), Safety Data Sheet (SDS), allergen declaration (contains milk), non-GMO statement and country of origin certificate are available on request at no additional charge. Halal and Kosher certificates can also be provided for eligible batches.

FDCM delivers to all 27 EU member states via our DSV road freight partnership. Standard transit time is 3–7 business days depending on the destination country. For deliveries outside the EU or for time-critical shipments, please contact us directly.

Yes. Acid casein is derived from bovine milk and is classified as a major food allergen under Regulation (EU) No 1169/2011. It must be declared in ingredient lists and allergen statements for finished products. Our allergen declaration document, available on request, confirms the presence of milk protein and the absence of other major allergens in standard production runs.

Yes. Acid casein is used as a protein ingredient in sports nutrition formulations, typically in protein powders, high-protein bars and meal replacement products. Its slow-digestion profile is relevant for nighttime protein and sustained-release applications. For ready-to-drink or water-soluble formulations, consider sodium caseinate instead. For food supplement classification and labelling compliance in the EU, refer to Regulation (EU) No 1169/2011 and applicable national rules.
