要旨

Fractionation of complex matrices such as biomass into diverse functional biomolecules without disrupting the biomolecule functionalities is a real challenge. Known separation processes are designed for the recovery of single products such as hydrophilic proteins or hydrophobic pigments, discarding the other products as waste. Here we present a concept for one-step biorefinery of hydrophobic and hydrophilic biomolecules from complex matrices using an ionic liquid-based surfactant free emulsion stabilised by microgel particles, while maintaining the product integrity. We demonstrate the process by simultaneous extraction of pigments and proteins from a microalgae extract; the hydrophobic pigments are transferred to the ionic liquid droplets and the proteins to the aqueous continuous phase. In contrast to most solvent extraction procedures, with this concept, the proteins retain their nativity, opening up an extraction pathway to fully functioning proteins while harvesting hydrophobes. A perspective towards continuous operation of this novel process is presented.

Reaction Chemistry & Engineering is an interdisciplinary journal reporting cutting-edge research focused on enhancing the understanding and efficiency of reactions. Reaction engineering leverages the interface where fundamental molecular chemistry meets chemical engineering and technology. Challenges in chemistry can be overcome by the application of new technologies, while engineers may find improved solutions for process development from the latest developments in reaction chemistry. Reaction Chemistry & Engineering is a unique forum for researchers whose interests span the broad areas of chemical engineering and chemical sciences to come together in solving problems of importance to wider society. All papers should be written to be approachable by readers across the engineering and chemical sciences. Papers that consider multiple scales, from the laboratory up to and including plant scale, are particularly encouraged.
