摘要
Abstract
An analytical method was established to determine fructooligosaccharides (FOS) in milk and milk products by high performance ion exchange chromatography method with pulsed amperometric detection. The column was a CarboPac PAl (4 mm x 250 mm) anion exchange column. Fructooligosaccharides were separated under gradient elution mode. The mobile phase A was 150 mmol/L NaOH and the mobile phased B was composed of 150 mmol/L NaOH and 100 mmol/L sodium acetate. The relative standard derivations for 6 replicate determinations of four fructooligosaccharides in liquid milk were less than 9%. The average spike recovery rates for three fructooligosaccharides in liquid milk varied between 94.8% and 103.6%. The method was simple, fast and suitable for determining FOS in milk and milk products.关键词
