Wheat kernels with high moisture levels usually exhibit high levels of α-amylase. The Hagberg Falling Number (HFN) test is used as an indicator of the level of alpha-amylase enzyme in the sample.

1961 Sven Hagberg named the method “falling-number” with a simple modification. 1962 Harald Perten founded Perten Instruments and commercialized falling number apparatus. The Hagberg Falling Number (HFN) test is used as an indicator of the level of alpha-amylase enzyme in the sample. MILLING AND BAKING The enzyme alpha-amylase has long been known to be produced in the early stages of germination. The Hagberg falling number is the measure of a specific enzyme, which is used to determine suitability of wheat for bread making, with higher numbers preferred by millers. Effective crop nutrition management particularly of nitrogen and potassium can help increase the Hagberg falling numbers.
The Amylab FN applies the principles of the Hagberg method while using innovative technologies. The Hagberg Falling Number measurement, widely used in the milling industry for assessing the baking quality of wheat flour, has been modified and used as a rapid mashing technique to assess malt quality. Barley Malt flour is mixed with cold mashing liquor containing 0.1% calcium chloride and 15 mM beta‐mercapto‐ethanol. The Hagberg falling number method is widely recognized as the standard for determi - nation of pre-harvest sprouting related weather damage in wheat, rye and other crops. Equipment for performing this analysis has long been dominated by one supplier with little innovation in the method or equipment.

Yield Hagberg falling number was reduced in some years due to fungicide treatment (Figure 14), but this difference was statistically significant only in three years out of 10 (1998, 2001 and 2002). The Hagberg-Perten Falling Number (FN) test is used to measure this problem in the wheat industry, and determines how much a farmer's wheat is discounted for PHS damage.
