This method is used for the determination of sulphur dioxide (SO2) in brown sugars and speciality sugars.
The method procedure is similar to that used in Method GS3-51 where the sulphite present is oxidised to sulphate. The difference being that the resultant sulphate is determined instrumentally using HPIC.
The method has been shown to have a limit of decision in brown sugar of 10 mg/kg and a limit of detection (LoD) of 20 mg/kg. For total sulphite content up to 70 mg/kg, the absolute difference between two results obtained under repeatability conditions should not exceed 8 mg/kg and under reproducibility conditions should not exceed 15 mg/kg.
