AB  - The purpose of the present work was the experimental evaluation of pesticides 
      transfer to virgin olive oil during the production step and prediction of their 
      processing factors, which could be eventually used for the calculation of maximum 
      residue limits (MRLs) in olive oil from the MRLs set in olives. A 
      laboratory-scale Abencor system was used for the production of olive oil from 
      olives spiked with the 104 pesticides studied, three different chromatographic 
      methods being used for the analysis of raw olives and the obtained olive oil: (i) 
      gas chromatography-tandem mass spectrometry (GC-MS/MS) for GC-amenable 
      pesticides; (ii) hydrophilic interaction liquid chromatography-tandem mass 
      spectrometry (HILIC-MS/MS) for polar pesticides, and; (iii) reversed-phase liquid 
      chromatography-tandem mass spectrometry (UHPLC-MS/MS) for low to medium polarity 
      pesticides. Processing factors experimentally calculated were correlated to their 
      octanol-water partitioning coefficient (logK(ow)), enabling the calculation of 
      the equivalent MRLs in olive oil from the MRLs in olives, considering the 
      percentage of oil extracted (oil yield) and the log K(ow) of each pesticide.
