Olive mill wastewater Phenolic compounds Bioavailability Safety Beverage formulation A B S T R A C T The biological activities of phenolic compounds from olive mill wastewater (OMW) have extensively been studied, and shown a spectrum of highly interesting bioactivities. These properties demonstrate the potential of OMW extract for inclusion into food and beverages. This contribution provides an overview of key research describing the phenolic profile of OMW associated with health promoting activities including the impact of processing and storage on its composition, safety and the bioavailability. The potential application of OMW for the preparation of functional beverages and the impact of beverage formulation factors on bioavailability of OMW phenolics are discussed. Based on the available studies, phenolic compounds of OMW are highly bioavailable and safe. Owing to the numerous reported biological activities of OMW, the inclusion of OMW phenolic extract in beverage preparations may have a significant impact on the health of population through the reduction in incidence of cardiovascular and chronic degenerative diseases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
