This method is suitable for the determination of low reducing sugar contents, e.g. in white sugars including specialty white sugars and plantation white sugars [4] up to 0.05%. Such low levels cannot satisfactorily be determined by titration against Fehling’s solution. This method is designated the ICUMSA Official (Reference) method 2, it is the method that ICUMSA recommends for the Determination of Reducing Sugars in White Sugar and Plantation White Sugar in preference to Method GS2/9-6.
