Fucoxanthin’s optimization from undaria pinnatifida using conventional heat ext...
Lourenço-Lopes, Catarina; Fraga-Corral, Maria; Soria-Lopez, Anton; Núñez Estévez, Bernabé; Barral Martínez, Marta; Silva, Aurora; Li, NingyangBrown macroalgae are a potential source of natural pigments. Among them, Undaria pinnatifida is recognized for its high concentration of fucoxanthin (Fx), which is a pigment with a wide range of bioactivities. In this study, three independent parameters were optimized for conventional heat extraction (CHE) to maximize the recovery of Fx from Undaria pinnatifida. Optimal conditions (temperature = 45 °C, solvent ...
