Introduction
Algal antioxidants, derived from microalgae and macroalgae, are emerging as potent bioactive compounds in nutraceuticals, cosmetics, pharmaceuticals, and functional foods. These compounds—such as astaxanthin, fucoxanthin, phycocyanin, and beta-carotene—exhibit strong free-radical scavenging activity, offering natural alternatives to synthetic antioxidants. Rising consumer awareness of clean-label, sustainable, and plant-based ingredients is fueling demand across global markets.
The Evolution
Initially limited to academic interest and traditional Asian health practices, algal antioxidants have advanced through improved cultivation techniques, bio-refinery models, and scalable extraction technologies. Early market players focused on microalgae like Haematococcus pluvialis and Spirulina platensis. With advancements in closed-loop photobioreactors and selective strain development, production yields and purity have increased.
Recent innovations include eco-friendly solvent extraction, supercritical CO₂ methods, and use of algae biomass as co-products in food and animal nutrition. The narrative has shifted from niche application to industrial-scale viability—backed by clinical trials and sustainable harvesting practices.
