Many of the main parameters for malting barley quality and malting process analysis may be measured with one fast, versatile, and cost-efficient solution: the VideometerLab. A general presentation of the capabilities can be found here.
For a malt producer barley quality is of paramount importance. A mold infection will potentially destroy the malt and may be catastrophic for the breweries, that are the malt customers. To secure the quality of the finished malt and its further use for brewing it is important to analyse the incoming barely in order to assure the quality of the malt. The VideometerLab instrument inspects an incoming barley sample for a number of the most important quality parameters. This is done fast, accurately, non-destructively, and simultaniously. This is also cost-efficient since is does not need time-consuming sample preparation or chemicals.The parameters are:
Incoming barley may be inspected 8-9 grams at a time in 90 mm petri dishes. This is flexible but often we need to test larger samples then VideometerLab can be equipped with the autofeeder option shown below.
With the autofeeder it is possible to measure samples between 50-1500 g. Running the same sample through many times over several months and adulterating a large sample (560 g) with a handful of Fusarium spp. grains shows that this analysis has a high reproducibility among several presentations and over time. It also shows that the sensitivity is high compared to the variation of the analysis.
The VideometerLab is calibrated based on various cultivars from all over the world. The calibration has been validated by the Carlsberg Research Center. For more information see the paper here.
Here you can see a comparison between the VideometerLab measurements and the level of Fusarium DNA quantified by Real-time PCR, giving an excellent correlation with Fusarium DNA level (R2=0.85).
For a malt producer it is important to accurate control and progress the different stages of the malting process. In order to do this then a number of important parameters can be measured along the malting process line.The parameters are:
All four malting process analyses are performed by the same VideometerLab instrument, and the automated recipes are illustrated in the images to the right. All recipes may be adjusted for other grain types like wheat.
