This study reports, a green biorefinery strategy, for purifying and concentrating phenolic compounds of different molecular weight such as caffeic acid (MW 180.16 g/mol), chlorogenic acid (MW 354.21 g/mol) catechin (290.26 g/mol) and ellagic acid (320.197 g/mol), from fennel wastes. The process consists of a centrifugal extraction of fennel wastes followed by a sequential treatment of the fennel extract by microfiltration (MF) and nanofiltration (NF) operations. the proposed process can be a promising approach to increase the added value of fennel wastes within the logic of circular economy, reducing at the same time the environmental impact due to their disposal.

Abstract
This study reports, a green biorefinery strategy, for purifying and concentrating phenolic compounds of different molecular weight such as caffeic acid (MW 180.16 g/mol), chlorogenic acid (MW 354.21 g/mol) catechin (290.26 g/mol) and ellagic acid (320.197 g/mol), from fennel wastes. The process consists of a centrifugal extraction of fennel wastes followed by a sequential treatment of the fennel extract by microfiltration (MF) and nanofiltration (NF) operations. the proposed process can be a promising approach to increase the added value of fennel wastes within the logic of circular economy, reducing at the same time the environmental impact due to their disposal.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
