Artichoke, is one of the richest sources of polyphenols and antioxidants, these
substances can be incorporated into foods due to their antioxidant,
anticarcinogenic and anti-inflammatory properties. According to literature some
agricultural residues belonging to Artichoke, have been used for the bioactive
components extraction such as flavonoids and phenolic compounds. In this
vein, this research focuses on the metabolites (total phenols) extraction
artichoke bracts as well as the measurement of antioxidant activity in a
continuous monitoring extraction system. For the extraction process 180 g of
“Blanca de Tudela” artichokes bracts of 7.95 cm in diameter were used. During
the experiments different stirring velocities, particle sizes, temperatures (20, 40,
60 ºC) were employed. Extraction performed at 60ºC shown the highest yield in
total phenols, as a result of increase of transfer mass rate. Results also
demonstrated a temperature relation between polyphenols compounds
recovery and the solubility. The extraction of artichoke bracts at 60 ºC presented
greater antioxidant activity and higher yields of total phenols that their
counterparts. Finally, an extraction in turbulent convective conditions using
particles sizes less than 10 mm promotes a cheaper extraction process.
