Casein makes up approximately 80% of total milk protein, existing as large colloidal micelles (50–500 nm in size). This size difference is the key to separating it efficiently. Here's the membrane technology stack: 🔹 Microfiltration (MF) — 0.1–0.2 µm pore size Selectively retains casein micelles while allowing whey proteins, lactose, minerals, and water to pass through as permeate. This produces a native casein concentrate with minimal denaturation. 🔹 Ultrafiltration (UF) — 1–100 kDa MWCO Used to further concentrate the casein-rich retentate, removing residual water and small solutes while retaining protein mass. 🔹 Diafiltration (DF) Washing steps using water or permeate to purify the casein concentrate — flushing out non-protein components and improving protein purity to 85–95%+ on a dry matter basis. The result: Native Micellar Casein Concentrate (MCC) — a high-value ingredient with intact micelle structure, superior functional properties, and exceptional nutritional bioavailability. Key advantages over acid or rennet precipitation: ✅ No chemicals used — clean label ✅ Native micelle structure preserved ✅ Higher solubility and dispersibility ✅ Continuous process — scalable for industrial volumes ✅ Whey proteins recovered separately as a co-product A single process step. Two premium protein streams. 📊 Process Advantages: • Continuous operation vs. batch = higher throughput per shift • No acid/alkali inputs = lower raw material cost & cleaner effluent • Dual protein recovery: casein concentrate + whey protein permeate • Reduced water consumption through closed-loop diafiltration 📦 Product Advantages: • Native Micellar Casein Concentrate (MCC) commands a premium vs. acid casein • Higher solubility = broader application range in food & pharma • Clean label positioning — no chemical precipitation agents • Consistent composition batch-to-batch 🏭 Applications unlocked by membrane-produced casein: → Sports & performance nutrition (slow-release protein) → Cheese analogue manufacturing → Infant formula (A2 casein fractions) → Pharmaceutical excipients & drug delivery systems → Industrial adhesives, coatings & bioplastics What MF/UF systems is your plant currently operating?
