Abstract: The nutrition composition in the seed kernel of white pitaya was analyzed.The results show the following contents:32.02% (mass fraction‚the same below) of fat‚22.06% of protein‚21.03% of starch‚10.35% of rough fiber‚5.80% of moisture‚3.18% of ash and1.75% of total sugar.The amino acid and fatty acid compositions of the protein in the seed kernel were also analyzed‚showing80.83% of unsaturated fatty acid content in fatty acid‚and in unsaturated fatty acid‚54.43% of linoleic acid con-tent———the highest of all.

Key words:  white pitaya, seed kernel, nutritive composition
