title: [Determination of patulin in foodstuffs Part II: Determination of patulin in tomatoes, pears, apples cucumbers and plums (author's transl)].
abstract: An analytical method for the determination of Patulin in tomatoes, pears, apples, cucumbers and plums is described. The determination limit of the method is 40 mug Patulin/kg. With additions between 100-500 mug Patulin/kg the recovery rates lie between 86--95%. After a pre-purification of the crude extract by column chromatography and liquid-liquid extraction the Patulin is determined thin-layer chromatographically by reflectance measurement at 273 nm.
