Fate of Food-Relevant Toxic Plant Alkaloids during Food Processing or Storing and Analytical Strategies to Unveil Potential Transformation Products.

Toxic plant alkaloids (TPAs) may contaminate food and pose a threat to consumer health; as a consequence, they are undesired in foodstuff or food commodities. Similar to other ingredients, TPA may be affected by storing or processing of food, often associated with decreased levels of the parent alkaloids. Up to now, little is known about potential transformation products or if they still may exhibit toxic potential to consumers. This perspective briefly summarizes the current knowledge regarding the behavior of opium, pyrrolizidine, and tropane alkaloids toward processing or storing and highlights analytical strategies to identify and elucidate potential transformation products.
