What is ICUMSA Methods Book.pdf?

If you are involved in the sugar industry, you may have heard of or used ICUMSA Methods Book.pdf. But what exactly is it and why is it so useful? In this article, we will explain what ICUMSA Methods Book.pdf is, what it contains, how to access it, how to use it, and what are its advantages and limitations.

ICUMSA Methods Book.pdf


ICUMSA stands for International Commission for Uniform Methods of Sugar Analysis. It is a non-profit organization that was founded in 1897 with the aim of providing an information service to its members on standardized methods of sugar analysis. Its members include national committees from various countries, as well as individual experts from academia, industry, government and other institutions.

ICUMSA methods are procedures that describe how to measure different parameters or properties of sugar products, such as sucrose content, reducing sugars, color, ash, pH, etc. These methods are based on scientific principles and best practices, and are validated by collaborative testing among laboratories. They are widely used by sugar producers, processors, traders, regulators and researchers around the world.

The ICUMSA Methods Book.pdf is a document that contains all 124 adopted ICUMSA methods as of 2022. It is available as a print version or an eBook version. The print version can be ordered from Bartens Verlag GmbH (, while the eBook version can be downloaded from ICUMSA website ( The methods book is also available in Spanish, Portuguese, Russian and Polish languages.

Overview of the ICUMSA methods book

The ICUMSA methods book covers a wide range of sugar products, such as raw sugar, white sugar, brown sugar, juice, syrup, molasses, speciality sugars, etc. The methods are classified into 10 groups according to the product type and the parameter measured. For example, group GS1 refers to methods for raw sugar, group GS2 refers to methods for white sugar, group GS3 refers to methods for solution color, and so on.

The main features and benefits of the ICUMSA methods book are:

  • It provides a comprehensive and authoritative source of information on sugar analysis methods.

  • It ensures consistency and comparability of sugar analysis results among different laboratories and countries.

  • It supports quality control, trade, regulation and research in the sugar industry.

  • It reflects the latest developments and innovations in sugar analysis techniques and instruments.

  • It is updated and revised regularly by ICUMSA experts and committees.

The ICUMSA methods book is revised every four years to incorporate new or revised methods, as well as corrections and clarifications. The latest edition of the methods book was published in 2022, and it contains 124 methods, of which 83 are official, 19 are accepted, 21 are tentative and one is withdrawn. The official methods are those that have been approved by ICUMSA after meeting all the requirements, such as collaborative testing, validation, etc. The accepted methods are those that have been proven to be useful and reliable, but do not lend themselves to collaborative testing. The tentative methods are those that are still under evaluation or development. The withdrawn method is one that has been replaced by a newer or better method.

How to use ICUMSA Methods Book.pdf?

Now that you know what ICUMSA Methods Book.pdf is and what it contains, you may wonder how to use it effectively. In this section, we will provide some general guidelines and recommendations on how to select, follow, interpret and report ICUMSA methods. We will also give some examples of ICUMSA methods for different sugar products.

General guidelines and recommendations

The first step in using ICUMSA Methods Book.pdf is to select the appropriate method for the parameter and sample type that you want to measure. For example, if you want to measure the polarimetric sucrose content of raw sugar, you can choose between method GS1-1 (VIS-polarimetry) or method GS1-2 (NIR-polarimetry). You can find the list of methods and their descriptions in the table of contents or the index of the methods book. You can also use the search function on the ICUMSA website ( to find the method that suits your needs.

The second step is to follow the method instructions and specifications correctly. Each method has a standard format that includes the following sections:

  • Title: The name of the method and its status (official, accepted or tentative).

  • Scope: The parameter measured, the range of application, the product type and the sample preparation.

  • Principle: The scientific basis or mechanism of the method.

  • Apparatus: The equipment, instruments and accessories required for the method.

  • Reagents: The chemicals, solutions and standards required for the method.

  • Procedure: The step-by-step instructions on how to perform the method.

  • Calculation: The formula or equation used to calculate the result from the measurement.

  • Precision: The repeatability and reproducibility data obtained from collaborative testing.

  • Bibliography: The references or sources used for developing or validating the method.

You should read and understand each section carefully before applying the method. You should also follow the safety precautions and quality assurance measures recommended by the method. You should use only certified or traceable reagents and standards, and calibrate your instruments regularly. You should also perform blank tests and check tests to verify your results.

The third step is to interpret and report the results obtained by the method. Each method specifies how to express the result in terms of units, decimal places, rounding off, etc. You should also indicate any factors or conditions that may affect the result, such as temperature, humidity, sample age, etc. You should also compare your result with the expected value or range based on previous data or literature. You should also report any deviations or errors that occurred during the method application.

Examples of ICUMSA methods for different sugar products

To illustrate how to use ICUMSA Methods Book.pdf in practice, we will give some examples of ICUMSA methods for different sugar products. We will not go into details of each method, but only highlight some key points and features.
