Abstract :
Peach byproducts are ofen regarded as food waste despite their high content in health-promoting components. Amongst the
latter, polyphenols are bioactive molecules with signifcant health benefts. Te present study investigated an eco-friendly and costefective method using a GRAS food additive, �-cyclodextrin (�-CD), for the recovery of polyphenols from peach pomace. �-CD
assisted extraction of polyphenols was compared to that of conventional solvent (ethanol) extraction at the same concentrations
(10 mg/mL, 20 mg/mL, 30 mg/mL, 40 mg/mL, and 50 mg/mL) in terms of quality (antiradical activity) and quantity. Te extract
obtained by 50 mg/mL �-CD assisted extraction showed the highest polyphenol (0.72 mg GAE/g DM) and favonoid (0.35 mg
catechin/g of DM) concentrations as maximal antiradical activity (6.82%) and a noted antibacterial activity. Our results showed the
competitiveness of �-CD assisted extraction to recover a high quantity and quality of polyphenols from peach pomace suggesting
�-CD as a green alternative method for phenolic extraction.
