Current strategies for non-target food screening focus mainly on known hazardous chemicals (adulterants, residues, contaminants, packaging migrants, etc.) instead of bioactive constituents in general and exclude the biological effect detection. To widen the perspective, a more proactive non-target effect-directed strategy is introduced to complement food safety in order to detect not only known but also unknown bioactive compounds.

A non-target effect-directed screening was developed to reveal estrogen-like and antiestrogen-like compounds in 15 rosé, white and red wine samples of different origin and grape variety. Normal-phase high-performance thin-layer chromatography multi-imaging detection (NP-HPTLC-UV/Vis/FLD) was combined with the planar yeast estrogen screen (pYES) bioassay or the duplex planar yeast antagonist estrogen screen (pYAES) bioassay on the same adsorbent surface.

Changing lifestyles and eating habits made meal replacement products in the forms of shakes and bars a good alternative as , promoted as balanced in its composition and thus healthier compared to other ready-to-eat meals. This study aimed to evaluate the bioactivity of six differently flavoured powdered meal replacement products.

However, the important active portion of natural food or plant-based medicine is presently not under control. Hence, a paradigm shift from quality control based on marker compounds to effect-directed profiling is postulated.

Current workflows are too tedious for routine use. Hence, the hyphenation of separation and detection techniques is a powerful tool to maximize the information obtained by a single sample run.
