This project focused on the development and validation of an ultra-performance liquid chromatography tandem mass spectrometer (UPLC-MS/MS) method for the determination of Patulin in apple-based products. Patulin is one of the many mycotoxins that are secondary metabolites from about 60 filamentous fungi. The mold often appears as black or blue on fruit, vegetables or crops. To determine the concentration of Patulin in consumer products is important since it may affect consumer health. The symptoms are often flu-like and can lead to kidney-failure and neurotic damage. The Swedish Food Agency is tasked to analyze consumer products to determine if they are safe to ingest. The European Commission has set maximum residue limits for several toxins that can potentially appear in groceries on the market. Using an UPLC-MS/MS allows for the accurate qualification and quantification of Patulin in apple juice and purees. The method was validated by analyzing several lots of apple juices and a proficiency test from Fapas®. The recovery rate ranged between 70.5-103.8% and were accepted because they met the recovery criteria in Regulation (EC) No. 401/2006 for Patulin.
