ABSTRACT
Food industry is a global and fast-growing industry, with business and research networks still in a phase of transition. Additionally, high-value bioactive compounds (lipids, proteins, and carotenoids) and by-products derived from algae are being investigated for sustainable production of food and nutraceuticals. Moreover, the algal biomass is one of the largest sources of proteins packed with essential amino acids, coenzymes, vita-mins, and minerals that makes it an attractive animal feed specifically due to its high protein content-rich (40–60%). However, the utilization of these algal nutrients (proteins and other bioactive extracts) in daily life-style in terms of food products is not yet fully explored. This chapter provides an insight to the commercial products and metabolites derived from algae for commercially viable large production. It outlines the major species used and their key role in food, nutrition, animal feed and medicine. This will help in controlled scale-up production of the target compound for production of targeted molecule via a sustainable source of production.
