Carotenoids and polyphenols are the two groups of secondary plant products in the focus of our research. Besides bioavailability and metabolism, biological activities are under investigation. In addition, process steps of food processing are investigated to minimize the losses of secondary plant products.
Methods
- Analysis of food ingredients (HPLC-DAD, HPLC-MS/MS)
- Determination of biological activities of secondary plant products (Photometry, Fluorimetry)
- Investigations on bioavailability (in vitro digestion model, human intervention studies)
