Electric fields as a promising technology for the recovery of valuable bio compounds from algae: Novel and sustainable approaches
| Summary: | The development of more efficient and sustainable technologies for the recovery of valuable compounds holds the ability to change the paradigm of the use of resources. Electric field-based technologies have been regarded as highly promising towards an efficient extraction of biometabolites while addressing sustainability. Algal biomass is a potential valuable resource. Besides its nutritional value, it provides a wide range of bio compounds with a variety of industrial applications in different sectors (e.g., food, feed, cosmetics). Implementing a cascade biorefinery approach based on electric-fields application would boost the production of high-value-added products from algal biomass, opening up new opportunities for the development of a flourishing blue bioeconomy. This review paper provides an overview of the use of alternative extraction technologies in algae biomass, focusing mainly on electric field-based methodologies, suggesting cascade biorefinery approaches considering different alternative technologies depending on the target fraction, and envisaging their environmental sustainability and economic feasibility. |
