【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 and 1.75% of total sugar. The amino acid and fatty acid compositions of the protein in the seed kernel were also analyzed,showing 80.83% of unsaturated fatty acid content in fatty acid,and in unsaturated fatty acid,54.43% of linoleic acid content——the highest of all.更多还原
