Kinetic Extraction of Fucoxanthin from Undaria pinnatifida Using Ethanol as a Solvent.

ABSTRACT: Fucoxanthin (Fx) has been proven to exert numerous biological properties, which makes it an interesting molecule with diverse industrial applications. In this study, the kinetic behavior of Fx was studied to optimize three variables: time (t-3 min to 7 days), temperature (T-5 to 85 °C), and concentration of ethanol in water (S-50 to 100%, v/v), in order to obtain the best Fx yield from Undaria pinnatifida using conventional heat extraction. The Fx content (Y₁) was found through HPLC-DAD and expressed in µg Fx/g of algae sample dry weight (AS dw). Furthermore, extraction yield (Y₂) was also found through dry weight analysis and was expressed in mg extract (E)/g AS dw. The purity of the extracts (Y₃
