The Falling Number Apparatus developed by Sediroglu Group is a precision laboratory instrument used to determine alpha-amylase enzyme activity in wheat, flour and other cereal products. Alpha-amylase plays a critical role in starch degradation and directly influences fermentation, dough structure and final bread quality. Accurate measurement of enzyme activity is essential for controlling grain quality, flour blending and baking performance.
The test method is based on internationally accepted standards and evaluates the liquefaction rate of a flour-water suspension under controlled heating conditions. During the analysis, the sample is gelatinized in a boiling water bath while a standardized stirrer moves through the paste. The time required for the stirrer to fall through the gelatinized mixture is recorded as the Falling Number value. Low Falling Number results indicate high enzyme activity, often caused by sprouted grain, while high values reflect low enzyme activity.
This system ensures precise temperature control, automated timing and consistent test conditions to deliver highly repeatable and reliable results. The integrated correction capability allows accurate evaluation under varying environmental conditions. The Falling Number Apparatus supports grain intake control, flour quality classification and enzyme standardization in milling laboratories.
Designed for durability and ease of operation, the instrument provides stable performance in intensive laboratory environments. It is an essential analytical solution for flour mills, grain traders and cereal processing facilities seeking consistent and standardized quality control.
