Application of Novel Extraction Technologies for Bioactives from Marine Algae

Marine
algae are a rich source of bioactive compounds. This paper
outlines the main bioactive compounds in marine algae and recent advances
in novel technologies for extracting them. Novel extraction technologies
reviewed include enzyme-assisted extraction, microwave-assisted extraction,
ultrasound-assisted extraction, supercritical fluid extraction, and
pressurized liquid extraction. These technologies are reviewed with
respect to principles, benefits, and potential applications for marine
algal bioactives. Advantages of novel technologies include higher
yield, reduced treatment time, and lower cost compared to traditional
solvent extraction techniques. Moreover, different combinations of
novel techniques used for extraction and technologies suitable for
thermolabile compounds are identified. The limitations of and challenges
to employing these novel extraction technologies in industry are also
highlighted.
