The right casein will depend on your application and desired functional properties. When minerals are added to caseins to create caseinates, interactions occur that change how the protein behaves, affecting factors like solubility, heat stability and digestion rate. As a result, each type offers unique functional and nutritional properties that determines their suitability for different applications.
For instance, calcium caseinate is the most versatile option. It’s high in calcium, neutral in taste and suitable across various formats from beverages to bars and bakery products. Whereas sodium caseinate offers faster digestion, making it ideal for pre-workout applications. Then there’s specialised caseinates which use minerals like potassium, ammonium and magnesium for dietary-specific formulations or applications with unique nutritional requirements, such as low-sodium or magnesium-fortified products.
To achieve diverse functional properties, caseinates can also be dried in different ways. Spray dried calcium caseinates offer excellent solubility and clean flavour profiles, making them suitable for high-protein beverages and applications needing smooth, stable dispersions. For applications requiring a richer, more developed flavour profile, calcium caseinates can be roller dried.
