Which is the best food emerging solvent: IL, DES or NADES?

摘要

Background: Bioactive compounds have been intensely studied because of their biological properties that provide health benefits. However, for chemical or biological applications, these compounds are obtained mostly by using organic solvents. Emergent technologies consider the combination of methods and process optimization to improve the utilization of raw material, decreasing process costs, time and energy consumption. Additionally, due to the arising interest for green processes, alternative solvents have been developed. Ionic liquids (IL), deep eutectic solvents (DES) and, recently, natural deep eutectic solvents (NADES) can show high ability to extract organic, inorganic and polymeric bio-compounds. Overall, these promising solvents are environmentally friendly and less toxic than conventional extraction solvents.
