**5. Conclusions**

DES can be used as green solvents substituting conventional solvents, which could be toxic. Eutectic mixtures have a great extractability of anthocyanin compounds due to differences in physicochemical characteristics. However, a systematical study is necessary to observe how each property (viscosity, polarity, solubility, pH, among others) or multiple properties of each DES mixture affects the extraction performance (exploring the potential link between properties) and including the external variables such as temperature and time. Besides, is important to know the nature of the target compound to select the ideal DES, which is why one unexplored area could

be the solvent design using computational techniques and further application/evaluation in the laboratory, based on different molecular properties. On the other side, multiple assisted methods could be used to improve extractions like ultrasound or microwave together with DES, the need to explore other technics such as pulsed electric fields, high hydrostatic pressures, among others could be also an interesting field of research. Furthermore, the investigation of conservation by different methods like encapsulation and application in food matrices is necessary in order to increase the interest in anthocyanin extraction with DES.
