Abstract:
Formerly: The Determination of White Sugar Solution Colour - Official This Method is suitable for determination of the colour in solution of all crystalline or powdered white sugars and very pure syrups having a colour less than or equal to 50 ICUMSA Units (IU). The absorbance of a filtered solution is measured at 420 nm in a spectrophotometer. The Method is not suitable for sugars that contain additives to an extent that filtration is not practical. The Method has Official Status and if a choice of method is available then ICUMSA recommends that Method GS9-8 is used preferentially for sugars with a colour in solution greater than or equal to 20 IU. For sugars less than or equal to 50 IU, the absolute difference between two results, obtained under repeatability conditions, should not be greater than 3 IU. For sugars with ICUMSA Colour values up to 50 IU, the absolute difference between two results, obtained under reproducibility conditions, should not be greater than 7 IU.
