Summary

Pigments are widespread molecules that color plants and many animals and play crucial roles in photosynthesis and photoprotection. This chapter provides an overview of current and potential applications of chlorophylls, carotenoids, and phycobiliproteins from marine organisms like seaweeds, microalgae, and cyanobacteria. Aquaculture is a major user of pigments to improve organoleptic properties and health of livestock. Pigments are used as dyestuff in cosmetics and as skin care agents in cosmeceutical products (photoprotection, anti-inflammatory, or antioxidant effects). Due to the potential of pigments in health, functional food and nutraceuticals constitute another field of application. Current applications of pigments are limited with regard to the numerous bioactivities reported in recent decades. Factors responsible for the lack of applications as pharmaceuticals are highlighted. Pigments can also be used in various other applications since they exhibit interesting physical properties as dyes or fluorescent probes in optical microscopy. Despite more than 50 years of clinical use in humans, the main advantage of natural pigments over synthetic pigments is that most of the former are known not to be toxic. Moreover, marine natural sourcing (microalgae and seaweeds) can be sustainable, thanks to their rapid turnover rates, which makes them a choice alternative to synthetic analogs and to terrestrial sources. Crucial information about the different sources of pigments, bottlenecks in the overall valorization process, and some relevant key points regarding regulation are also pinpointed. Taken together, the most important elements covered in this chapter can be used in the framework of projects aiming to valorize pigments within blue biotechnologies.
