1. the detection method of Determination of galactooligosacchariin in infant food, is characterized in that, comprise the steps:

  • (1) adopt the galactooligosaccharide identical with the product trade mark of the galactooligosaccharide added in sample as reference material, be mixed with the standard working solution of variable concentrations;

    (2) sample of two parts of equals in quality is taken, portion adds described reference material, mark-on liquid is made into after being dissolved in water, another part directly adds water and is made into the sample liquid of same volume, described mark-on liquid and described sample liquid are added in ion chromatograph successively together with described working fluid after pretreatment and carries out gradient elution, and obtain chromatogram respectively;

    (3) filter out for quantitative specific peak after the chromatogram of described mark-on liquid and described sample liquid being contrasted, matching obtains the typical curve of described working fluid, the peak area of specific peak finds out concentration corresponding on described typical curve in liquid chromatography figure per sample again, obtains Determination of galactooligosacchariin in infant food.
