title: [Determination of patulin in foodstuffs. Part I: Determination of patulin in apple juice (author's transl)].
abstract: For the determination of Patulin in apple juice a method of analysis was developed permitting the detection of 40 microng Patulin/kg apple juice. With additions between 120--200 microng Patulin/kg the recovery rates lie between 82 and 90%. After a pre-purification of the crude extract by liquid-liquid extraction and column-chromatography the Patulin is determined thinlayer chromatographically by reflectance measurement at 273 nm.
