Application of Astaxanthin and Carotenoids Derived from Algae for the Production of Nutraceuticals, Pharmaceuticals, Additives, Food Supplement and Feed

The importance of astaxanthin and carotenoids for the production of nutraceuticals, pharmaceuticals, additives, food supplement and feed cannot be overemphasized due to several health benefit among which are anti-inflammatory and immune booster properties in people and animals. They are a major natural source of pigments and are high in antioxidants that have been documented to be more competent compared with vitamins C, E, carotene, lutein, lycopene, zeaxanthin, etc. Therefore, it's vital to explore the use of astaxanthin and carotenoids from algae; hence, this chapter discusses the potentials of optimizing astaxanthin and carotenoids from macro- and microalga cells. Utilization of astaxanthin and carotenoids from algae must be extended beyond serving as a food colorant by leveraging its powerful antioxidant potentials as a scavenger using microencapsulation to reduce oxidation damage which is germane in treatment of several documented health challenges. Hence, considering the future prospects of maximizing astaxanthin and carotenoids produced from algae as a major raw material in manufacturing of nutraceuticals, pharmaceutical products, and nutritional supplements on an industrial scale for the global market is a progressive phase towards attaining sustainable technology and agriculture that is eco-friendly and supports healthy living of humans and animals.
