Sample Preparation Tools for Chromatographic Testing of Beer
The German/Bavarian “Reinheitsgebot” (purity law) for beer is one of the oldest food purity laws (1516, most known version) that is still regarded, defining as acceptable raw ingredients water, barley, yeast and hops. Hence there is a long tradition of focus on the purity and quality of this food product that continues into our industrialized days. As agricultural processes have developed to significantly larger dimensions, and the use of chemicals like pesticides is common in the production of the raw materials, attention needs to be put on how much of these can or do end up in the final product. In this presentation we will address the efficient sample preparation and determination for pesticides.
And then, of course, there is the taste, another key property of beer, that is created by the chosen ingredients and the way in which they are used. Here Klaus Buckendahl will cover efficient sample preparation and determination for pesticides, as well as solid phase microextraction (SPME)-GC for automated raw material profiling, process control, and QC in beer.
Attend this presentation to:
- Hear insights on pesticide analysis in hops by QuEChERS with improved recovery for planar pesticides
- Learn how SPME can be utilized as an efficient tool for the profiling of flavor compound such as terpenes, aldehydes and other compounds in beer.
