Essentially Cynomorium spirulina tablets are manufactured from the cynomorium extract and spirulina powder through direct molding production process.By using egg protein as the standard protein,the WHO / FAO amino acid reference model as assessment criteria,through the fuzzy identification method and the ratio coefficient of amino acids,Protein nutrition of cynomorium spirulina tablets are comprehensively assessed.The results are listed as follows: 1) The Cynomorium spirulina tablet contains 18 varied amino acids which occupy 42.75% of the total content;2) There is a great variety of amino acids in proteins,and the essential amino acids(EAA) account for 36.5% of the total amount of amino acids;3) Tryptophan is the first limiting amino acid,the amino acid containing sulfur is the second one,and their amino acid ratio coefficients are 0.54 and 0.72 respectively.
