This paper discusses the changes observed in Water Vapor Transmission Rate (WVTR) of three plastic films while exposed to different concentrations of d-limoneme. The concentration of d-limoneme on the films was determined by means of Headspace Gas Chromatography and Mass Spectrometry. The Water Vapor Transmission rate of all films was determined by means of a MOCON-Water Vapor Permeation Analysis System Permatran-W 3/31. It was observed that d-limoneme affected the films in two ways: at lower concentrations, the WVTR decreased but, after certain concentration was reached, the WVTR increased. These results explain the shortened shelf-life of candies containing d-limoneme which are currently packaged with the studied films. Finally, this paper discusses all the experimental problems encountered on this study as well as possible improvements for future studies.
