Scope

This document specifies the liquid chromatography method for determining oligofructose in dairy products. This document is applicable to the determination of oligofructose content in dairy products. Principle: The sample is extracted with trichloroacetic acid solution, centrifuged after precipitating proteins, diluted with acetonitrile, and the supernatant is detected by a high-performance liquid chromatograph-evaporative light scattering detector. The oligofructose is identified based on the retention time of the chromatographic peak, and the quantification is performed using an external standard method.
