Abstract:
Brown algae are rich sources of bioactive compounds, including fucoxanthin (FX), which exhibits diverse biological activities, such as antioxidant, anti-inflammatory, antitumor, and metabolic regulatory effects. Processing critically influences these bioactivities, yet the structural transformations of FX and their biological consequences remain poorly understood. This review systematically summarizes the effects of processing methods (thermal treatment, drying, salting) and environmental factors (light, pH, oxygen) on FX content, structural integrity, and isomeric profile and discusses how these structural alterations-including isomerization, oxidation, and degradation-subsequently influence key bioactivities, including antioxidant defense, anti-inflammatory signaling, apoptosis induction, and lipid metabolism. Evidence indicates that specific isomers (e.g., 13-Z and 9'-Z) exhibit distinct functional properties. Therefore, optimizing processing conditions is essential for maximizing FX retention and functional efficacy. This review elucidates the processing-structure-function-mechanism relationship, providing a theoretical basis for high-value utilization of brown algae.
