Representation of those advanced and sustainable extraction techniques explored until date to obtain enriched-bioactive fractions from coffee pulp (the upper half). It includes the bioactivities studies until date and the compounds pointed as responsible of such properties. Moreover, non-explored extraction techniques, bioactive compounds and health-promoting activities are proposed (the lower half).
