ABSTRACT Fucoxanthin is a major carotenoid found in marine brown algae. This study investigated the impact of fucoxanthin on the growth performance, antioxidant metabolism and meat quality of broilers. Overall, 180 one-day-old male broiler chicks (Ross 308) were assigned to one control group (CONT) and 2 treatment groups (FUCO1 and FUCO2), with six replicates of 10 birds each. The CONT, FUCO1 and FUCO2 birds were fed a basal diet supplemented with 0, 100 and 200 mg/kg of fucoxanthin, respectively. Average body weight gain (BWG), feed intake (FI) and feed conversion ratio (FCR) were similar among the groups. Fucoxanthin increased catalase (CAT) and superoxide dismutase (SOD) activities and glutathione (GSH) levels (p<0.01), and reduced malondialdehyde...

The performance of microwaves irradiation (MAE and VMAE) to extract pigments from two marine microalgae was compared to conventional processes (cold and hot soaking and ultrasound-assisted extraction). Pigments were quantified by RP-HPLC and extraction performance was assessed regarding rapidity, reproducibility and extraction yields. Scanning electron microscopy was used at all extraction steps to assess the impact of the process on microalgal cell integrity. Freeze-drying and pigments extraction preserved microalgae cell integrity (except sonication) and evoked agglutination in superposed cells layers. All processes performed on Dunaliella tertiolecta (chlorophyte) lead to rapid pigments extraction, and equivalent pigments extraction yields, the absence...
