A treatise on ICUMSA solution colour – Part 2: Studies and conclusions

Hanjo Puke; Christiane Lakenbrink;

The article summarizes the discussions in ICUMSA during the past 15 years on methods for determining the colour of sugar in solution. The 28th Session of ICUMSA, held in Cambrigde (UK) in 2012, successfully closed the long-lasting work on standardization of methods for this most important quality parameter for sugar. The Official Reference Method GS9/1/2/3-8 fixes the solution pH to 7.0. Studies of colour determination at pH = 6.4 did not improve the precision of the measurement.

Key words: sugar, colour in solution, pH value, ICUMSA Methods
