    On the current Fos standard products market,it only has GFn oligomer standard products but lack of Fn oligomer standard products. The separation conditions for Fn oligofructose monomer from fructooligosaccharides mixtures derived from inulooligosaccharides were optimized by the Taguchi method in this study. The results showed that the sample concentration was the most significant factor for inulin separation. The optimum separation could be obtained at flow rate 0.05 m L/min,sample concentration 100 g/L,sample volume 2 m L and elution solution of 5% ethanol with the column of Bio-Gel-P4(2.0×100 cm). The sample then submitted to Bio-Gel-P2(2.0×100 cm)column chromatography,the optimum separation conditions were: flow rate 0.05 m L/min,sample concentration 100 g/L,sample volume 1 m L and elution solution of 5% ethanol. Under the above optimum conditions,the product from Bio-Gel-P4 column was concentrated and separated by Bio-Gel-P2 column chromatography. The purity of F3 was ≥ 98%, and F4 was ≥ 90
