Enzyme-Assisted Extraction of Bioactive Compounds
Summary
Enzyme-assisted extraction harnesses the specificity and mild operating conditions of hydrolytic enzymes to liberate intracellular bioactives such as polyphenols, flavonoids and oligosaccharides from plant matrices. By targeting polysaccharide networks in cell walls with cellulases, hemicellulases, pectinases or tannases, the technique reduces reliance on harsh organic solvents and high temperatures. When combined with physical intensification methods—such as ultrasound, pressurised fluid or supercritical carbon dioxide—the process achieves higher yields, shorter extraction times and enhanced selectivity for target compounds. This green-chemistry approach addresses growing demand for natural functional ingredients in foods, nutraceuticals, cosmetics and pharmaceuticals. Key challenges remain in enzyme cost, immobilisation, recovery and scale-up. Recent advances focus on integrated continuous processes, in situ enzyme production, tailored enzyme blends and predictive modelling of enzyme-substrate interactions. The result is a more sustainable route to high-value extracts that meet stringent purity and safety standards, opening new opportunities for circular valorisation of agro-industrial residues on a global scale.

Enzyme-Assisted Extraction of Bioactive Compounds publication trend
The graph below shows the total number of articles in enzyme-assisted extraction of bioactive compounds across all publications each year (not limited to Nature Index journals).
Technical terms
Enzyme-assisted extraction (EAE): Use of specific hydrolases to degrade cell-wall polymers and release intracellular bioactives under mild conditions.
Supercritical fluid extraction (SFE): Extraction technique employing a fluid above its critical temperature and pressure (commonly CO₂) to solubilise and recover target compounds.
Ultrasonic-assisted extraction (UAE): Application of high-frequency sound waves to create cavitation and enhance mass transfer during extraction.
Polyphenols: A broad class of plant secondary metabolites characterised by multiple phenolic rings, known for antioxidant and health-promoting properties.
Flavonoids: Subgroup of polyphenols with a 15-carbon skeleton, including flavonols, flavones and anthocyanins, valued for bioactivity and colour.
Prebiotic: Non-digestible compounds that selectively stimulate growth or activity of beneficial microorganisms in the host.
