Response Surface Optimization of Inulin and Polyphenol Extraction from Artichoke (Cynara scolymus (L.)) Solid Wastes

Artichoke wastes after processing represent 60–70% of the raw material and are a potential source inulin polyphenols, bioactive compounds that can be valorized as food ingredients or nutraceutical products. The aim this work was to assess optimize extraction these from artichoke using water water–ethanol mixtures extracting agents. For simultaneous polyphenol achieve high antioxidant activity in extracts, best process conditions an agent were T = 89 °C t 139 min, where 80% content, 60% total phenolic content (TPC) 56% (Aox) obtained. extractions, results obtained with EtOH 22.4%, 81 217 leading yields 90% TPC, 38% Aox 58% content. From results, we recommend use for recovery polyphenols wastes. Although yield is lower treatments, amount extracted considerable it greener option when compared mixtures.
