Abstract: The goal of this study was to evaluate patulin contamination in 'Galaxy' and 'Fuji Kiku' apples subjected to controlled atmosphere (CA) and dynamic controlled atmosphere (DCA) conditions. Experiments were performed and fruit were stored for nine months under refrigeration plus 7 days shelf life at 20 °C. CA and DCA were not effective in preventing patulin production in either 'Galaxy' or 'Fuji Kiku' apples. Healthy fruit were not contaminated with patulin, even when stored together with decayed apples. For 'Galaxy' apples, application of 1-methylcyclopropene increased the percentage of fruit with decay and patulin contamination. Patulin concentrations were above the maximum limit (50 μg kg <superscript>-1</superscript> ) established in the Brazilian legislation, meaning the use of CA and DCA conditions were not advantageous in preventing patulin accumulation. In 'Fuji Kiku' apples, there was no significant difference in patulin concentration among CA, DCA-CF and DCA-RQ 1.3 treatments, and all were below the maximum.<br /> (Copyright © 2018 Elsevier Ltd.
