Applications of Macroalgae in Pigments
Applications of Macroalgae in Pigments Macroalgae (seaweeds) are rich in bioactive pigments, which are essential for their survival in marine environments. These pigments not only contribute to the colors of macroalgae but also offer a wide range of industrial and commercial applications. In recent years, there has been growing interest in macroalgae as a source of natural pigments due to their potential use in food, cosmetics, pharmaceuticals, and other industries. These pigments include chlorophylls , carotenoids (such as astaxanthin and fucoxanthin), phycobiliproteins , and anthocyanins , all of which have different functional properties. 1. Carotenoids Carotenoids are a group of naturally occurring pigments found in many macroalgae, particularly in red and brown seaweeds. These pigments are responsible for the yellow, orange, and red colors in macroalgae. The most studied carotenoids in macroalgae are astaxanthin , fucoxanthin , and β-carotene . A. Astaxanthin ...
