ICUMSA Methods Book: The Ultimate Resource for Sugar Industry Professionals

ICUMSA Methods of Sugar Analysis presents the recommendations of the International Commission for Uniform Methods of Sugar Analysis (ICUMSA) that are based on thorough investigations of methods likely to prove practical and appropriate for the sugar industry. 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.

In spite of their high degree of accuracy, physical methods can only be used for the titration of pure sucrose solutions. If solutions are more complex, with the presence of reducing sugars, colorants, or flavor enhancers, chemical methods can be employed to determine sucrose content. The most widely used chemical methods are chromatography [10, 11] and reducing sugars, which are based on the reducing properties of free carbonyl group in reducing sugars, reacted with a copper solution in alkaline medium [12]. 2ff7e9595c
