Industrialization of hydrodynamic cavitation in plant resource extraction

Imagine extracting plant compounds with bubbles that collapse with the force of a thousand atmospheres — that's hydrodynamic cavitation, and it's ready to leave the lab.

Hydrodynamic cavitation (HC) is no ordinary stirring. Inside a liquid, bubbles form, grow, and collapse under pressure changes, generating extreme temperatures up to thousands of Kelvin, shockwaves up to 1000 bar, and reactive hydroxyl radicals. This makes it a powerful, scalable tool for extracting bioactive compounds from plants — and it aligns with green extraction principles.

Already, HC shows promise in making vegetable beverages and beer. But industry hesitates: innovation resistance and capital costs for retrofitting existing plants are real barriers. For dry extracts rich in bioactive compounds, the energy bottleneck is water removal, so maximizing biomass concentration is key. That means intensifying cavitation is a research priority.

This short review surveys recent studies and offers practical recommendations to push HC toward real industrialization. The message is clear: the science works; now it's about strategy.
