Casein

✨Product Desctiption

Casein is the predominant phosphoprotein found in mammalian milk, constituting approximately 80% of total milk protein. It is a family of related phosphoproteins (αS1, αS2, β, and κ) that form three-dimensional colloidal supramolecular micelles. Casein is an amphiphilic protein with excellent emulsification, foam formation, stabilization, water-binding, and gelation properties.

🧩 Applications

Food & Beverage Industry
Casein is widely used as a food additive and functional ingredient. It serves as a stabilizer, emulsifier, and thickener in dairy products, frozen foods, baked goods, meat products, and seasonings. It is a key ingredient in protein formulations, functional blends, cheese and yogurt production, infant formula, sports nutrition products, and high-protein blends, bars, and powders. Casein is also used as a whitening or thickening agent in nondairy foods and protein supplements.

Adhesives & Binders
Casein glues are used in exterior and interior woodworking, labeling adhesives in the bottling industry, and water-based glues. Casein also functions as a binder in paper coatings, pigment and mineral binders in industrial coatings, and drug binders in the pharmaceutical industry.

Coatings & Packaging
Casein exhibits excellent film-forming properties and intrinsic oxygen-barrier capabilities, positioning it as a sustainable alternative to petroleum-based plastics in food packaging. Casein-based coatings, latexes, and bioplastics are being developed as environmentally friendly options. It is used in protective coatings for paper and cardboard, textile coatings, and water-resistant, biodegradable films.

Paints & Coatings
Casein is used in water-based paints, emulsion paints, and as a pigment binder in industrial coatings.

Paper & Textile Industry
Casein serves as an ink binder in the paper industry, paperboard coatings, and textile sizing. It is also used in leather finishing and textile coating applications.

Cosmetics & Personal Care
Caseinates are used as emulsifiers and conditioners in cosmetic products.

Pharmaceutical & Medical
Casein is used as a substrate for proteases including bromelain, chymotrypsin, pepsin, and trypsin. It also serves as a drug binder in pharmaceutical formulations and has applications in drug delivery systems.

🏭 Storage Conditions

• Temperature: Store at room temperature (10–30°C) in a cool, dry place. For optimal long-term storage, temperatures below 25°C are recommended.

• Humidity: Keep away from moisture and high humidity environments. Casein is hygroscopic (absorbs moisture from the air) and should be stored in a dry environment.

• Light: Store in a shaded place away from direct sunlight.
