AB  - Fumigation of transport containers is common practice to protect stored products 
      from pests. Yet little is known about the desorption times and effects of the 
      highly toxic gases used in this process. To shed light on the behavior of 
      fumigants in real food, we treated sunflower seeds (Helianthus annuus L.) with 
      100ppm phosphine (PH(3)), methyl bromide (MeBr) or 1,2-dichloroethane (DCE) for 
      72h. The compound concentrations in the air were then analyzed by thermal 
      desorption/2D gas chromatography coupled to mass spectrometry and flame 
      photometric detection (TD-2D-GC-MS/FPD). A desorption time of several months was 
      observed for DCE, whereas PH(3) and MeBr were outgassed in a matter of days. To 
      investigate possible interactions between gases and constituents of the seeds, 
      non-fumigated, fumigated and outgassed samples were analyzed by headspace 
      solid-phase microextraction GC-MS. We observed significantly different volatile 
      profiles in fumigated and subsequently outgassed seeds compared to non-fumigated 
      seeds. Whereas PH(3)-treated seeds released far more terpenoids, the volatile 
      pattern of seeds exposed to DCE revealed significantly fewer terpenoids but more 
      aldehydes. These changes are likely to affect food aroma characteristics.
