Food Chemistry Research Group

Tracking the constituents of food.

The purpose of the Food Chemistry research group is to analyse value-determining constituents of food.

We investigate the occurrence, impact and relevance of food constituents on food composition. Furthermore, we explore their potential uses in cosmetic products.

Our research group combines sensory and instrumental analytical methods in order to establish innovative food processing techniques. Our aim is to extract as many valuable constituents as possible from raw food materials and to preserve them during processing.

Many of our research projects are conducted in close collaboration with partners from science and industry and include research conducted by our students.

Research and Services

In the Food Chemistry research group, we mainly focus on the following activities:

Aroma Analysis

Aroma is an essential quality criterion for food products. It is responsible for consumer acceptance and popularity of food products. For this reason, we investigate aroma composition using methodologies that combine human odour detection and instrumental analysis that decodes aromas on a molecular level. Using state-of-the-art aroma research technologies, we examine aroma constituents of different food groups such as cocoa, chocolate, vegetable oils, bakery products, fruit, vegetables, herbs, spices, and  alcoholic and non-alcoholic beverages. Furthermore, the above mentioned techniques also enable us to investigate the appearance of off-odours in diverse food matrices.

Analysis & Extraction of non-volatile food constituents

The preservation of value adding food constituents during technical processing is one of the main goals of our institute. Analysing selected food constituents helps us to better understand processes, and to be able to control and optimise them. Apart from the analysis of different quality and safety markers along selected food value chains, we focus our research activities on the extraction and chemical characterisation of polyphenols. Furthermore, we also investigate the chemical and physical properties of alternative proteins.

Cosmetic & Personal Care

We process value adding ingredients and by-products from food production processes into innovative beauty and nutrition products, allowing us to create value sustainably. In our formulation laboratory, we develop cosmetic product prototypes at a laboratory scale of between 1 and 3 kg. We also investigate the physical and chemical stability of these prototypes using rheological indices, as well as microscopic picture and instrumental analysis of their active components. In addition to this, we perform sensory analysis of cosmetic products in order to optimise product formulas.

Our Infrastructure

Our modern laboratory infrastructure and our analytical expertise allow us to comprehensively analyse value determining food constituents along the whole food value chain – from field to fork. Furthermore, our equipment enables us to target the extraction of selected food constituents and then apply them in different food and cosmetic products.
