CDR BeerLab® - simple, fast and reliable analysis system of beer.

Determination of Starch in beer and wort

In the mashing phase starch is converted in fermentable sugars by specific enzymes (amylase) present in the malt. A control of the real conversion can be made measuring the residual starch in wort, so that you can continue with the remaining operations.
With CDR BeerLab® systems it is possible to obtain reliable results on starch immediately, carrying out the analysis during the mashing phase, directly in brewery.


Test Principle

Starch reacts with a solution of stabilized iodine, producing a violet coloring, measurable at 620 nm in end point.

Calibration Curve

The calibration curve was made using samples with known starch value. The trend of the curve confirms the excellent linearity of the system over the entire measurement range.
