Algal Pigments, a Natural Approach to Coloring

 Seagriculture EU 2024

The public is beginning to demand safer, more natural colorings for foods, and algae is rising to the occasion. Production of synthetic pigments is currently much cheaper, but natural pigments are superior to synthetics due to high antioxidant capacity, increased digestibility, anti-cancer, and anti-inflammatory properties.

Carotenoids are pigments found in orange, yellow, and red that are generated by a variety of microorganisms, including bacteria and algae. Certain species of algae and cyanobacteria create phycobiliproteins, which come in red, blue, and purple hues. The algae pigment industry has the potential to generate revenue while having environment benefits including carbon capture and bioremediation.

In this video — created by Eleanor Wood as part of the 2021 Biophysical Society video contest – we get a glimpse at natural algal pigments and the amazing colors that can be extracted from microalgae.
