About the Special Issue

Over the past two decades, eutectic mixtures have been extensively explored as green alternative liquid media to traditional organic solvents and are applicable in a wide variety of industries targeting sustainable chemistry. The word “eutectic” comes from the Ancient Greek εὔτηκτος which means easily melted. A eutectic point represents the chemical composition and temperature at which a mixture of two solids becomes fully molten at the lowest melting temperature, relative to that of either compound. Natural Deep Eutectic Solvents (NADES) are composed by cellular constituents such as sugars, alcohols, amino acids, organic acids and choline derivatives, representing a breakthrough in the field of Green Chemistry. They offer numerous advantages including biodegradability, low toxicity, solute stabilization, sustainability, low costs and simple preparation. Furthermore, NADES are compatible with every step of the Total Analytical Process. Considering NADES are composed of food-grade ingredients that would not need to be removed before use, they represent an attractive alternative for the nutraceutical products field. Additionally, NADES can enhance physico chemical and biological properties of the materials, including stability, texture, strength, stiffness, toughness, durability antioxidant and antimicrobial properties.  Thus, it is possible to design advanced functional materials mediated by Natural Deep Eutectic Systems for use in the food and pharmaceutical industries. These materials may include a range of products such as packaging, edible films, coatings, nanoparticles and hydrogels. The main aim of this issue will be to contribute innovative topics of the application of NADES in food chemistry and food materials. 

In this very wide context, we invite investigators to submit both original research and review articles that explore all these aspects.
