Aplicación de la tecnología de fluidos supercríticos en la extracción, concentración y formulación de aceite de pescado rico en omega3una nueva estrategia para la revalorización de subproductos de pescado

Abstract

Due to their benefits to human health, the demand of omega-3 fatty acids, especially EPA and DHA, in the food and the pharmaceutical industries has been highly increased in the last years. As consequence, the development of cost-competitive, safe and eco-friendly omega-3 production processes has become an important field of research all over the world. Recently, novel green technologies based on the use of supercritical carbon dioxide have acquired an enormous interest to produce high value compounds such as omega-3. On the other hand, the valorisation of fish by-products as a source of omega-3 rich oil has been considered an outstanding strategy to reduce the waste generation and increase the competitiveness in the fish industry. In this line, the present work deals with an application of supercritical fluids in extraction, concentration and formulation of omega-3 rich oil using fish by-products as a raw material.
