Migration studies

Greenaway et al. studied the migration of volatiles from poplar container to fruits, vegetables, poultry and cheese, identifying polyphenols fenilaldehydes and ketones.

Mousavi developed a mathematical model to predict migration from wooden forms with spherical and cylindrical through gas chromatography and mass spectroscopy, and experimental validation of volatile compound with benzaldehyde as marker. He concluded that the model, in the absence of published scientific data, would be useful to legislate the food contact material.

Mousavi concludes "After this study, we conclude that the above timber volatile substance is susceptible of migrating to food. However, its low concentration mass (between 0.5 and 17 mg / g in the poplar veneer) in packaged food, its form and its diffusion coefficient greatly reduce the risk of poisoning. Moreover, the drying of wood before use reduces further the concentration of pollutants.

Waymel also concluded in the toxicological suitability of different pine species for food contact based on an assessment after record and study the migration of alpha-pinene, the principal monoterpene of wood, along with other compounds such as beta-pinene, 3 carene, camphene, myrcene and limonene.
