Falling Number Tester – Laboratory Uses, Wheat Quality Testing & Grain Sprouting Detection
Grain quality assessment plays a critical role in food processing, milling, and agricultural research. Laboratories and quality control facilities require standardized testing methods to evaluate wheat and flour performance before processing. Analytical instruments designed for grain testing support accurate measurement of enzymatic activity, helping industries maintain product consistency and processing efficiency.
The Falling Number Tester LZ-FNT-A100 is used to determine the level of alpha-amylase enzyme activity in wheat and flour samples. This parameter is essential in assessing grain quality, especially in detecting pre-harvest sprouting, which directly affects baking performance and end-product characteristics.
What Is a Falling Number Tester?
A Falling Number Tester is a laboratory instrument used to measure the time required for a stirrer to fall through a heated slurry of flour and water. The recorded time, known as the falling number, reflects enzyme activity within the sample.
Higher falling number values indicate lower enzyme activity, while lower values suggest higher alpha-amylase activity, often associated with sprouted or damaged grains. This test is widely used in grain quality laboratories and flour mills for standardized wheat evaluation.
Falling Number Tester Working Principle
The operation of the Falling Number Tester is based on controlled heating and viscosity measurement. A flour or grain sample is mixed with water and heated in a boiling water bath. As the mixture gelatinizes, a stirrer moves through the sample.
The time taken for the stirrer to fall through the paste is measured in seconds. This value provides an indication of enzyme activity and starch degradation. The method follows standardized procedures commonly used in grain quality testing laboratories.
