This work aimed at developing and optimizing, for the first time, a sustainable process, with low environmental impact, to purify and concentrate low molecular weight polyphenols (mainly caffeic and chlorogenic acids) from fennel waste extract. The process consists of an aqueous extraction of fennel wastes followed by sequential microfiltration (MF) and nanofiltration (NF) processes. A detailed investigation of effects of operating conditions on permeate flux and separation efficiency of the NF membrane for caffeic and chlorogenic acids, was undertaken.

Abstract
This work aimed at developing and optimizing, for the first time, a sustainable process, with low environmental impact, to purify and concentrate low molecular weight polyphenols (mainly caffeic and chlorogenic acids) from fennel waste extract. The process consists of an aqueous extraction of fennel wastes followed by sequential microfiltration (MF) and nanofiltration (NF) processes. A detailed investigation of effects of operating conditions on permeate flux and separation efficiency of the NF membrane for caffeic and chlorogenic acids, was undertaken.File in questo prodotto:
