Abstract: The method is suitable to determine mannitol content in beet sugar products to follow the extent of deterioration due to the activity of Leuconostoc species during long periods of beet storage or during beet sugar processing.
This method is applicable to beet juices, raw juices, thin juices and syrups.
Precision has not yet been determined in international collaborative studies.
A national collaborative study yielded the following results.
The mean repeatability limit (P = 95%) which can be expected for raw juice mannitol contents above 20 mg/L has been estimated to be 7 mg/L.
The mean repeatability limit (P = 95%) which can be expected for thin juice mannitol contents above 20 mg/L has been estimated to 6 mg/L.
Reproducibility has been estimated to be 8 mg/L for raw juices, it should be better for thin juices.
