1,2-dehydropyrrolizidine alkaloids (PA) and PA-N-oxides (PANO) are phytotoxins, which presumably occur in more than 6000 plant species worldwide. Plants containing PA/PANO are responsible for various food and feed poisonings recorded for decades. Main reasons of exposition of consumers and livestock are contaminations of food and animal feed with parts, seeds, pollen or nectar of PA containing plants. Concerning stability, effects of processing on PA were mainly investigated in the past. The current study examined the behavior of PA/PANO in unprocessed matrices peppermint tea, hay and honey during storage...
