Summary
This narrative review examines extraction technologies for producing algal extracts rich in biologically active compounds whilst avoiding toxic solvents and degradative conditions. The authors compare classical and novel extraction methods, including supercritical fluid, microwave-assisted, ultrasound-assisted, enzyme-assisted, and pressurized liquid extraction, along with biomass pretreatment strategies. The review notes that safe algal-derived products have potential applications as agricultural biostimulants, bioregulators, feed additives, and in food, cosmetic and pharmaceutical industries.
Regional applicability
The review is technology-focused and methodology-centred rather than geography-specific. Findings on extraction techniques and pretreatment methods are globally applicable and relevant to United Kingdom agricultural and food production sectors seeking sustainable alternatives to synthetic inputs or conventional extraction methods.
Key measures
Extraction efficiency, preservation of biologically active compounds, comparison of extraction technique advantages and disadvantages, biomass pretreatment methods
Outcomes reported
The review compares classic and novel extraction techniques (supercritical fluid, microwave-assisted, ultrasound-assisted, enzyme-assisted, pressurized liquid extraction) for producing algal extracts containing biologically active compounds. It evaluates methods to minimise degradation of bioactive compounds and reviews biomass pretreatment approaches.
