What is Casein?
Casein is the primary protein found in milk, accounting for about 80% of its protein content. It exists in the form of micelles and is slow-digesting, making it ideal for sustained protein release. Casein is extracted during the cheese-making process and further processed into various forms, including:
- Rennet Casein
- Acid Casein
- Caseinates (sodium, calcium, potassium)
- Hydrolyzed Casein
Market Drivers
1. Rising Demand for Protein-Enriched Foods
As global consumers become more health-conscious, demand for high-protein, low-fat food and beverage products is growing. Casein is widely used in meal replacement products, sports nutrition, infant formula, and medical nutrition for its digestibility and amino acid profile.
2. Versatility Across Industrial Applications
Beyond food, casein is a valuable component in adhesives, paper coatings, textiles, paints, and even biodegradable plastics due to its excellent binding and film-forming properties.
3. Shift Toward Sustainable, Bio-Based Ingredients
With increasing pressure to reduce dependence on petroleum-based raw materials, casein’s natural and renewable origin positions it as an attractive option for eco-conscious manufacturers.
4. Expanding Dairy Supply Chains
Growth in milk production across emerging economies and improved casein extraction technologies are contributing to a more cost-effective and scalable supply chain.
