TUM Scientific Talk: Novel Analytical Methods for Vitamin B6 B9 B12

Featuring the Head of the Chair of the Analytical Food Chemistry of the Technical University of Munich (TUM), Prof. Rychlik will be discussing vitamin groups of folates (B6), pyridoxin (B9), and cobalamins (B12) and the novel analytical methods that have been developed. All of them are based on using stable isotope-labelled internal analogues of the analytes as internal standards for LC-MS/MS. These so-called stable isotope dilution assays (SIDAs) have been applied to various foods. For each vitamin group, significant sources to cover the recommended daily intakes (RDIs) will be presented. Moreover, the new SIDAs revealed novel vitamers and novel information on the distributions of vitamers in each group, which may affect bioavailabilities and efficiencies of supply. These aspects will also be discussed in the presentation.

SPEAKER

Prof. Dr. Michael Rychlik

TUM

 

Prof. Rychlik develops new analysis methods for physiologically active foodstuff ingredients such as mycotoxins, vitamins and flavonoids. In order to assess their biological activity, these substances and their metabolic products are examined in human, animal and plant testing. This provides information on bioavailability (e.g. of vitamins belonging to the folate group), toxicity (e.g. consumer exposure to mycotoxins deoxynivalenol and tenuazonic acid) or the positive effects of hops flavonoids (e.g. 8-prenylnaringenin).

After studying food chemistry at TU Kaiserslautern, Prof. Rychlik completed his second state examination (Staatsexamen) in 1989. In 1996, he did his doctorate at TUM on the topic of odorants in toasted bread. After that, he worked as an assistant professor at TUM’s Chair of Food Chemistry. He completed his lecturer qualification in 2003 on the topic of stable isotope dilution assays. He has declined offers from the Universities of Bonn and Giessen. Prof. Rychlik is Director of the Chair of Analytical Food Chemistry. Besides these he holds an Honorary Professorship at the University of Queensland, has been a Visiting Professor at the National University of Singapore and still is also teaching at the University of Chemical Technology Prague.
