If dichloromethane is swapped out and ethyl acetate is used in its place, the extracts then obtained would be highly anti-radical and would be more efficient than dichloromethane.
Since "like dissolves like," ethyl acetate is a polar molecule that works well as a solvent to extract the polar caffeine molecules from coffee beans. The ethyl acetate molecules bind to the caffeine molecules, which then move through the bean cells' cell membranes. After all, the ethanol:water (1:1) solvent combination has been demonstrated to be the best for recovering catechins and delivering extracts with the highest antiradical activity.
Dichloromethane is a volatile colourless liquid used as an organic solvent in many industries. One of its main application is that it used to extract caffeine because of its highly effective solvent nature. Because DCM is a non-polar solvent and caffeine is readily soluble in DCM, it can easily be extracted without losing its aroma.
