Description
This method is used to determine sucrose content in beet or cane molasses by polarimetry, taking into account the invert sugar content [1–5]. A diluted molasses sample is clarified using basic lead acetate solution before measuring the polarimetric sucrose content. The polarimetric measurement is repeated after acid hydrolysis of the clarified solution to obtain the invert sugar correction. Historically, this Method is known under the name “Herzfeld-Clerget double polarisation Method”. This method is not suitable for samples that do not produce a valid polarimeter reading for the procedure described.
