Permeation of volatile organic compounds (VOC's) through plastic bottles and closures of beverage and particularly beer

摘要

Alongside the advantages there is the problem of plastic's inherent permeability to gases and volatile organic compounds. However, there are no data available on permeation measurements of volatile organic compounds (VOC) through plastic bottles and contamination of beverages. Novel methods for the measurement of VOC have been developed. The presentation will show the new apparatus which enables the exposure of bottles in an environment that is enriched with defined concentration of solvents. The research results elucidate that the different barrier systems of plastic bottles show no sufficient guard for a permeation of VOC from atmosphere into the analysed liquid.
