New Evaluation of Honey Profiling at QSI

Since 2014 we evaluate honey into typical and untypical with their classical evaluation system. To be more clear and precise for our customers we decided to change the system.

The current system declares a honey into typical (as defined by the Annex I and II EU Honey Directive 2001/110) if no deviations in the parameters and the entire NMR profile (fingerprint of the honey) can be observed. An untypical honey shows indications of adulteration in the NMR profile mainly in the sugar area or also in deviating quality parameters.

From the beginning of August 2017 we will implement the new evaluation system. This system shall simplify and specify the evaluation of honey by means of NMR. In general if a honey comes in for testing we are looking for two aspects, first of all for adulteration with either sugar or syrup and second for the quality and authenticity of the honey. An addition of sugar or syrup would clearly lead to an “adulterated” honey evaluation and quality issues like high HMF concentrations or fermentation indicated by high ethanol content automatically to an untypical evaluation.

Meanwhile, we plan to extend the analyses with NMR spectroscopy from honey up to other substances like oils and essential oils.

Analysis of hemp products and cannabis

The popularity of products containing hemp (Cannabis) for industrial use (low in cannabinoids) is continuously increasing. Hemp seeds or protein powder produced from hemp are typical products available on the market. As the amounts of narcotic/psychotropic substances may differ considerably between different types of hemp it is crucial to know the exact content of these compounds in the product.
Analysis of these substances requires a special authorization by the Federal Opium Agency (Bundesopiumstelle) as the necessary reference materials belong to the group of narcotic/psychotropic substances. QSI holds this special authorization and is entitled to perform these analyses of hemp products.
