Moreover, species such as Spirulina and Chlorella with biological values of 77.6% and 71.6% respectively have not only been recognized as sources of high quality of protein, but also as potential sources of bioactive proteins.
Microalgal proteins comprise essential amino acids, specifically lysine and branched chain amino acid (BCAA) lucine, isoleucine and valine which account for 35% of the essential amino acids in human muscle proteins.
Compositional analysis of microalgae proteins clearly indicates that this high quality protein can be effectively used as direct supplements or could be used for formulation of other health products such as nutraceuticals.
