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.
The systems to test Starch in beer and wort
Starch levels can be measured using CDR BeerLab®, a system which enables you to carry out a wide panel of chemical analyses on beer and water, using a single instrument, in a process that is faster and simpler than traditional methods.
With CDR BeerLab® brewers and breweries of any size can independently carry out brewing process controls without having to rely on external laboratories.

Configuration with tailored panel of analyses
|Simultaneous Sample Analyses||16||3|
|Multiple Analyses on a Sample||–|
Test type: End Point.
Time testing: 1 minute.
Are possible test sessions with several samples, up to 16 tests for CDR BeerLab® and 3 tests for CDR BeerLab® Junior.
Calibration curve obtained with samples of known values.
Starch reacts with a solution of stabilized iodine, producing a violet coloring, measurable at 620 nm in end point.
Reagent test Kits
The reagents are packaged in foil pouches containing 10 tubes useful to perform 10 analyses.
This is the minimum package that allows the use of CDR systems even to those who need to make a few analyses, thus not wasting reagents.
There are also boxes of 100 tests, however, packaged in 10 bags of 10 tubes containing the reagent.
Code *300615 – The kit, designed for 10 tests
Code *300610 – The kit, designed for 100 tests
The reagents have a shelf-life of 6 months.
Processing of Sample Volume
Use on wort. For higher accuracy in the analysis of wort we recommend to centrifuge the sample.
