Abstract
The ion chromatography method was developed for the determination of fructo - oligosaccharide in milk powder by pulsed amperometric detector. The separation was carried out on CarboPac PA200 column using different elution,and column temperature under 30℃. The linear ranges of GF3 ,GF4 ,GF5 were 10. 0 to 50. 0 mg-L1 ,and spike recoveries rates were 73. 1% -82. 6% ,76. 4% ~ 82. 9% ,73. 8% -77. 6% ,and the detection limits werelO mg-kg'1, 20 mg-kg'1,24mg-kg"', and the RSDs were 3.22% -4.61% ,4.60% -4.94% , 1. 82% - 3. 26% . This method is applicable to the determination of fructo - oligosaccharide in milk powder.关键词
