It multiplies rapidly requiring only CO2, water, sunlight, and a small amount of minerals. It has 15 times more protein than soy, is an antioxidant, and is a source of vitamins C, B1, B2, B12, K, Zinc, Iron and Magnesium. Global production of Dunaliella is estimated to be 1200 tons dry weight per year [16]. Few advance countries have started culturing several microalgal strains of biofuel production, while countries like Libya, Cyprus, and Turkey also have plenty of marginal lands to harvest algae. The chapter is intended to provide an insight to two of the most important pigments obtained from microalgae, phycobiliproteins and carotenoids having species specificity which can be used as a chemotaxonomic marker. As a result of population growth, an emerging middle-class, and a more health-conscious society concerned with overconsumption of fats and carbohydrates, dietary protein intake is on the rise. Using photosynthesis, the microalgae absorb the light, as well as excess CO2, and use them as an energy source to create food. The presence of aortic atheromatous lesions was significantly inhibited, and low-density lipoprotein (LDL) cholesterol levels were greatly suppressed upon consumption of Chlorella [33]. Home > AFA is the "greenest" superfood known, because it contains so much chlorophyll (green photosynthesizing pigment). Microalgae have been used as traditional foods in various countries where suitable species occur naturally, such as Mexico and Chad. Moreover, algae are used in the food industry as food supplements and an addition to functional food. It also has anti-inflammatory properties and is used for various commercial applications in the dosage forms as biomass, capsules, creams, granulated powders, oils, soft gels, syrups, and tablets [39].
