Cost-effective freeze-concentration for organic acid processing
A novel freeze-concentration method to enhance organic acid concentration in fermentation broths, minimizing energy consumption and preserving quality. Ideal for applications in food processing and chemical industries.
Overview
This innovative freeze-concentration technology offers an energy-efficient solution for concentrating organic acids in fermentation broths. Unlike conventional evaporation methods, this approach significantly reduces energy consumption and preserves the sensory and nutritional quality of the acids. Originating from techniques used in the food processing industry, this method leverages the natural exclusion of organic acids during ice formation, resulting in higher concentration and purity levels.
Technical specifications
Key features:
- Utilizes ICECLES method for effective concentration of trace organic analytes
- Applicable to small organic acids, enhancing their concentration during ice formation
- Investigates critical factors such as ice formation method, stirring speed, and acid concentration
- Collaborative research involving organic and analytical chemistry expertise for comprehensive analysis and optimization
Technology readiness level
This technology is currently at TRL 4, indicating that it has been validated in the laboratory setting. Future research will focus on further optimizing the process for different small acids and exploring downstream separation and purification methods.
