Thermal-tailored protein for uht-stable high-protein beverages
A novel protein modification technique enhances heat stability and prevents color changes in high-protein beverages, ensuring clarity and stability at high temperatures without chemical additives.
Overview
The thermal-tailored protein technology offers an innovative solution for producing clear, ultra-high-temperature (UHT) stable high-protein beverages. This method involves a controlled pretreatment strategy that modifies proteins to withstand high temperatures, preventing coagulation and color changes. This approach is particularly beneficial for high-acid systems, as the proteins maintain their stability and reduce off-flavor notes even after exposure to temperatures of 140–145 °C for 6 seconds. The method uses commercially available GRAS-certified proteins like whey protein isolate and avoids chemical or enzymatic steps, making it cost-effective and scalable.
Technical specifications
Key features:
- Controlled molecular organization of proteins through specific temperature profiles
- Enhanced thermal stability and clarity in high-protein beverages
- Reduction in free sulfhydryl groups, minimizing off-flavors
- Compatible with various food-grade proteins
- Avoids chemical or enzymatic modifications, reducing costs and simplifying scale-up
Applications:
- High-protein, clear beverages
- High-acid to near-neutral pH systems
Technology readiness level
Currently, the technology is at TRL 3, indicating successful proof of concept. Future validation plans include optimizing modification conditions for different pH levels, testing with various protein sources, and pilot-scale UHT processing to further confirm thermal resistance and flavor stability.
