Flavour Chemistry Facility

The main focus of the flavour chemistry facility at the Teagasc Food Research Centre in Moorepark is the identification of volatile compounds that impact sensory perception of both foods and beverages. We have our own research program and extensively collaborate with other research groups nationally and internationally, but also provide a technical service to industry.

Background

Many thousands of volatile flavour compounds exist and it estimated that approximately 5-10% present in any food or beverage directly influences sensory perception. As these compounds are chemically diverse it is necessary to have a wide range of techniques in order to obtain representative data. The flavour chemistry facility has state of the art equipment and extensive experience from decades of research used to create databases of volatile compounds in a wide variety of foods and beverages. We also utilize chemometric approaches to look for correlations between volatiles and sensory data. For example, this knowledge can be utilized to identify off-odours, improve product stability, assess the impact of processing or ingredient changes, optimise sensory characteristics, for quality control or for authentication purposes.
