Abstract
The role of bioactive compounds in food as functional ingredients is increasingly recognized for their ability to enhance health and lower the risk of disease. Among these, seaweeds, particularly brown algae, stand out as significant sources of nutraceuticals with numerous health benefits. These marine plants are rich in natural bioactive compounds like phlorotannins, suggesting their promising applications in pharmaceuticals, cosmeceuticals, and food products. However, because little is known about efficient methods for extracting these significant components, the potential of brown seaweeds is still unexplored. Therefore, this review is aimed at discussing the bioactive properties of phlorotannins and the most efficient extraction and purification methods for these compounds. Furthermore, we review the anti-obesity, anti-cancer, and other health benefits associated with phlorotannins to provide an updated overview of these valuable natural components and their potential applications in food and nutraceuticals. By enhancing our understanding of phlorotannin, we can better harness its potential in promoting health and well-being, paving the way for innovative applications in the food industry and beyond.
