Sensory optimization of raw materials and products

Odor analysis: Characterization of odors & cause clarification of off-odors

Application area non-food: consumer goods, commodities, textiles, toys, raw, packaging and construction materials.

Many materials and products we use on a daily basis have a characteristic odor. If this odor is unpleasant or arises suddenly, the identification of all odorous substances in the relevant product can give important implications.

In order to identify the causes, possible negative physiological effects and opportunities for odor optimization, we carry out qualitative and quantitative sensory analytics. We identify possible reaction pathways and precursor substances that contribute to odor formation.

Our detailed knowledge of material properties is also utilized to develop strategies to avoid or minimize odor formation in a wide range of products and materials.

We support you comprehensively and purposefully in the characterization of odors as well as in the clarification of causes in case of interfering odors.

Our services on sensory optimization

Identification of the cause of off-odors

Identifying the causes of undesired odors is often challenging. We identify components, additives, and raw materials that are responsible for off-odors. Strategies for this include odor simulations and accelerated storage tests.

Characterization of odors

We characterize odorous substances in non-food products and raw materials. The combination of instrumental and sensory analyses allows us to precisely evaluate the sensory properties of materials and identify possible reaction pathways.

Real-time monitoring of odorants

Odorants often change over the life cycle of a product. Using inline measurements we are also able to detect minute concentration changes and hence monitor dynamic processes involving odorants in real-time.

Strategies for odor optimization

The overall sensory impression of a product has a large bearing on consumer acceptance. We develop strategies to prevent unpleasant odors.

Identification of irritants

In some cases volatile substances have adverse physiological effects. Innovative analytical methods based on techniques used in aroma research enable us to identify odorous components in a variety of products.

Quantitative determination

Traces of highly odorous substances often suffice to significantly alter the overall odor of a product. Our quantitative analyses enable very accurate measurement of odorous substances, even down to the trace level.

Analytical Equipment

We have state-of-the-art analytical equipment for online measurements of volatile organic compounds (VOCs) for analytical sensing.

VOC analytics

The analysis of volatile organic compounds (VOCs) is not only used for sensory product optimization but also to minimize harmful emissions.

Odor analysis for different products and applications

Children's products and toys

Plastic toys in sealed jars, scientists talking in background

Toys and other children's products often have a distinct odor. We identify these volatile components, possible reaction pathways, and their effect on the human body. We have already found that many substances lead to off-odors and irritation.

Further information about our services in the area of cause clarification of irritant effects and interfering odors in children's products.

Other product groups and raw materials

We can quantify volatile compounds in many other non-food products and materials, for example:

  • Packaging and products for food contact
  • Adhesives, binders
  • Cosmetics, bodycare products
  • Raw materials (e.g. fats and fat derivatives)
