This study aimed to assess the accuracy and reliability of new test methods which was developed to measure aroma permeability of food packaging materials. Two stainless steel permeation cells were specially designed to observe aroma permeation through various packaging films. Four different films (PP/EVOH/PP, EVOH, LDPE, COC) were tested on this experiment and six aroma compounds were selected, which generally contributed to coffee aroma. Permeated aroma compounds were quantified using HS-SPME in coupled with GC/FID. As a result, aroma compounds were rarely detectable via PP/EVOH/PP films and this suggest that multilayer films would be suitable for food packaging materials, especially susceptible to aroma loss. And test results performed in duplicate were consistent, which showed the technique used in this paper could be applied to determine aroma permeability of food packaging materials. |
