ICUMSA METHODS OF SUGAR ANALYSIS PDF

The Methods Book also contains polynomials and tables derived from the polynomials [4] which relate the refractive index of solutions of pure sucrose , glucose , fructose and invert sugar to the strength of those solutions. These are to be used with the analysis methods that characterize sugars by refractometric means but find wide application outside the sugar industry as the sucrose polynomial is built into the firmware of modern refractometers [5] and is the basis for calibration of purely optical refractometers which read in Brix. Temperature correction factors, also derived from the polynomials, are the basis for the Automatic Temperature Compensation features found in those instruments. This usually does not result in significant error. The ICUMSA is constituted of representatives from national committees designated by the governments of major sugar importing and exporting countries; the votes of these representatives are weighted according to the amount of sugar their countries import and export.

This book discusses the procedures for raw sugar polarization. Organized into two parts encompassing 21 chapters, this book begins with an overview of the various methods of determining sucrose by polarimetry, including the invertase method and the Jackson and Grill's method.

This text then examines the methods of determining reducing sugars, which depends on knowing the amount of cuprous oxide precipitated from Fehling's solution. Other chapters consider the method to be applied for all beet products. This book discusses as well the principle of double sulfation that is necessary to ensure conversion of ash to sulfate.

The final chapter deals with the evaluation of filter aids. This book is a valuable resource for chemists. We are always looking for ways to improve customer experience on Elsevier.
