Dextrans in sugars from Sao Paulo state

The characterization of dextran in sugars by size exclusion chromatography (SEC) has, been carried out according, to the number-average molecular weight (Mn). the weight-average Molecular weight (Mw), the Z-average molecular weight (Mz). and the polydispersity (Mw/Mn). The results Suggest that all the analyzed thirty sugar samples from Sao Paulo state were contaminated with two or three different dextran polymers. The collected data clearly point out that the total dextran content together with the mass distribution parameters Mw, Mn. Mz. and Mw/Mn should be considered during the evaluation of the quality of the sugar used for the cachaca sweeting process.
