Deep eutectic solvents (DES): An update on the applications in food sectors

Abstract

The food processing sector has expanded dramatically over the past ten years, particularly with regard to goods that are high in biologically active compounds. Thus, the efficacy and safety of food extraction techniques have also received attention. There is currently a sharp rise in research articles committed to the creation of new extraction techniques which are not only quick and affordable but also more effective and environmentally friendly, increasing yields and extract quality without the use of potentially dangerous organic solvents. The use of green solvents has been a focus of study to meet sustainable development goals. Deep eutectic solvents (DESs) are acknowledged as excellent alternatives to organic solvents due to their simpler manufacturing procedure with 100% atom economy, cheap cost, probable biodegradability, and negligible toxicity. DESs have become a popular and useful liquid with proven application in a variety of chemical reactions. Wide variety of food components may be extracted using DES, and they have been shown to be useful for applications involving food. However, the possibility for industrial scale-up use, however, has not been fully examined.
