Functional ingredients

Fraunhofer IGB focuses on the customized production and processing of functional ingredients from microalgae for the production of food and feed, cosmetics, biostimulants and biobased polymers. By means of targeted process management, these processes can be transferred to pilot scale. For faster process development, predictive models for control systems are used.

Furthermore, the focus is on processing technologies, such as the efficient extraction of carotenoids and omega-3 fatty acids with subcritical solvents and recovery of the individual components.

New non-thermal processing methods (pasteurization and cell disruption) are used to obtain high-quality ingredients in food and contribute to a healthy diet.

Thermal treatment (drying/torrefaction) of material flows with superheated steam and integration into a value-added chain will allow them to be processed more efficiently. Energy-efficient processes for the extraction of drinking and process water from air are designed for technical implementation.
