Analytical Method for the Determination of the Aroma Permeation through Synthetic Packaging Materials
One of the roles of a packaging material is to preserve the aromas of the packed product. In orderto choose the right material to preserve the aroma, it would be interesting to have the possibility to determinethe aroma permeation. To date numerous studies were realized concerning the permeation (or the mass transfer)of an aroma through a synthetic packaging material including the methods of analysis (dynamic or static(manual taking)). The purpose of the present study is to develop an automated and easy to operate analyticalmethod based on an autosampler static headspace feeding a chromatograph with gaseous phase coupled with amass spectrometer detector (HS-GC-MS) for the determination of the diffusion and permeability coefficientsfor a couple aroma /synthetic packaging material. To automate this method, a module of automatic pilotingand a measure cell conceived from an existing vial were developed. For the validation of the analyticalmethod, the couples composed of an aroma such as limonene and menthone and a volatile organic compoundas hexane and a synthetic material such as LDPE, OPP, OPET, OPA, PLA and metallised-PLA were studied.The results got by this method are compared with these one of the gravimetric method and the dynamicmethod GC-MS by electronic impact. So, the automated method static HS-GC-MS coupled with a module ofautomatic piloting is adapted for aroma /synthetic material couples presenting a high permeability coefficient.
