The quality of many everyday products as well as that of resources and materials is significantly determined by their sensory properties. In the event of an unpleasant odor, for instance, the combination of human sensory evaluation and the decoding of odor-active substances can provide important information for product optimization.
We conduct qualitative and quantitative analyses in order to answer any questions about the causes, possible negative physiological effects or optimization potentials. Thereby, we shed light on the potential formation pathways of these volatile compounds and their release from the respective materials.
Thanks to our comprehensive knowledge of material properties, we are also able to develop suitable avoidance or minimization strategies for a wide range of products and materials.
We support you extensively in the characterization of odors and in the cause clarification of unwanted odors as well as their release by means of real-time emission analysis.

Our research and development methods can be applied to any raw material or product across a variety of categories. Here is an overview of potential ways you can use our odor analysis services.
Packaging, composites, automotive components, materials
The decision on which packaging materials to use is nowadays increasingly determined by factors such as sustainability and resource efficiency. As a result, recyclable products and higher recycling rates are increasingly in demand and recycled plastics are becoming the material of choice. Yet many recyclates — especially recyclates from post-consumer waste — exhibit unwanted odors and therefore often do not meet the required quality level. We characterize these odor-active contaminants and develop customized solutions for odor optimization or minimization.
Coatings, cellulose, lignin, starch, paper, cardboard
The application of bio-based composites in everyday items such as toys and paper requires new developments in odor optimization. Particularly when using waste materials from the agricultural or food industry or substituting individual components in the development of bio-based product systems, quality losses in sensory properties may occur. Our extensive method portfolio enables us to evaluate the sensory properties of bio-based materials and products and to identify targeted solutions for their odor optimization.
Characterization and optimization of odorants in bio-based materials and products.
Adhesives, binders, plasticizers, stabilizers, pigments, additives
Technical auxiliaries serve an important role in optimizing production processes and improving the quality and properties of products. In many cases, it is only through the addition of various auxiliaries, such as adhesives, binders or stabilizers, that materials become technically usable. However, even the smallest amounts of such additives can lead to quality losses of the sensory properties of the end product. We identify unwanted odorants and develop targeted avoidance and minimization strategies.
