摘要：

The determination of transport properties of aroma components in polymers to be used in packaging applications remains a challenge, as there is no reliable commercial instrument or standard methodology to be applied. However, the significance of such measurements from a product application development point of view seems to be of paramount importance. In this pioneering study on the topic, we set the conditions and limitations of the FT-IR technique, and discuss the potential of a simple methodology to determine aroma transport in polymers. More specifically, we made an attempt to apply the technique in transmission to determine transport coefficients of pure and mixed citric aroma compounds during desorption from polyethylene and compared the results with those obtained from a conventional gravimetric method.
