Spirulina is immensely rich in nutrition below is the presentation of nutrition composition:-
The rate of protein in Spirulina is high and represents between 60% and 70% of the dry matter (Clément 1975b, Fox 1999) what is more than fish (25%) or soya (35%) (Henrikson 1994). With this rate of protein, 10g of spirulina bring between 6g and 7g of protein which represents almost 50% of a 10 kg child's needs. However, for the adults, the interest of spirulina as a hyper protein ingredient is limited.
The composition of the protein is balanced in amino acids and contains more than 40% of essential amino acids (Borowitzka 1988) like isoleucine (IIe), leucine (Leu), Lysine (Lys), methionine (Met), phenylalanine (Phe), threonine (Thr), tryptophan (Trp), and valine (Val).
However, the composition of Spirulina is too low in sulphur amino acids (cysteine and methionine) which are essential for malnourished people and especially children.
Even if it contains a large part of essential amino acids, spirulina must be associated with other protein sources rich in amino acids. We will use cereals rich in sulphur amino acids like rice mil which are common in Africa or legumes like sesame or pea.
