Cereals; determination of falling number

This document establishes a comprehensive methodology for determining the falling number in cereal grains, a critical indicator of grain quality and potential sprouting damage. The procedure defines precise laboratory conditions and equipment specifications necessary to ensure consistent and reproducible results across different testing environments. It outlines the step-by-step process for preparing grain samples, including milling and suspension in a water solution. The standard specifies the exact temperature and timing parameters required during the measurement phase, where the descent of a weighted stirrer through the gelatinized sample is recorded. By providing a unified approach, this specification facilitates reliable assessment of enzymatic activity, particularly amylase levels, which are inversely related to the falling number value. The defined protocol ensures that operators worldwide can evaluate grain suitability for baking and other processing applications with a high degree of confidence. Adherence to these technical guidelines allows for accurate comparison of samples from diverse origins, supporting quality control protocols in international trade and agricultural production systems without deviation from the core experimental principles.
