EVALUATION ON THE PROTEIN QUALITY OF CELOSIA CRISTATA L.LEAVES

Using the egg protein as standard protein and WHO/FAO reference model of essential amino acid (EAA) as an appraisal criterion,and putting 10 kinds of vegetal as a series of contrast,the authors evaluated the nutritional value of protein in Celosia cristata L.leaves by the method of fuzzy discernment and the method of ratio coefficient of amino acid (AA) respectively.The results showed that the protein contents of C.cristata L.leaves ranged from²3.7%～2.7.4% in the dried samples.The gross protein in 3 varieties of C.cristata L.leaves were rich in all kinds of AA,containing 83.47%～86.94% AA.EAA took up 40.2%～41.7% of total AA.The first limiting AA was sulfur containing AA,Met and Cys.The protein quality of C.cristata L.leaves was far superior to that of some common vegetables.Based on other nutrient components described by some papers,this species may be considered as a fine vegetal which can be exploited and used.
