“…Permeability of AITC vapor through the HDPE film (0.0254 mm) was determined using the permeation cell method of Hatzidimitriu and others (1987). The cell consisted of 2 stainless steel chambers (upper and lower), each having a volume of 50 cc, with the film sample placed between the chambers (Figure 1).…”

Listeria monocytogenes and Salmonella typhimurium are major bacterial pathogens associated with poultry products. Ally isothiocyanate (AITC), a natural antimicrobial compound, is reportedly effective against these pathogenic organisms. A device was designed for the controlled release of AITC with modified atmosphere packaging (MAP), and then evaluated for its ability to control the growth of L. monocytogenes and S. typhimurium on raw chicken breast during refrigerated storage. In order to obtain controlled release during the test period, a glass vial was filled with AITC and triglyceride. It was then sealed using high-density polyethylene film. The release of AITC was controlled by the concentration (mole fraction) of AITC in the triglyceride and by the AITC vapor permeability through the film. The fresh chicken samples were inoculated with one or the other of the pathogens at 10(4) CFU/g, and the packages (with and without AITC-controlled release device) were flushed with ambient air or 30% CO(2)/70% N(2) before sealing, and then stored at 4 degrees C for up to 21 d. The maximum reduction in MAP plus AITC (compared to MAP alone) was 0.77 log CFU/g for L. monocytogenes and 1.3 log CFU/g for S. typhimurium. The color of the chicken breast meat was affected by the concentration of AITC. Overall, a release rate of 0.6 microg/h of AITC was found to not affect the color, whereas at 1.2 microg/h of AITC the surface of the chicken was discolored.

“…Determination of AIT permeability through LDPE film Commercially available, low density polyethylene (LDPE) film was purchased from Bangsanhyundai (Seoul, Republic of Korea). The AIT permeability of the film (20 μm thickness) was determined as described by Hatzidimitriu et al (1987) with slight modifications. For the determination of AIT permeability, a quasi-isostatic cell with upper and lower polycarbonate chambers was constructed.…”

ABSTRACT:The permeation parameters of commercial poly(ethylene terephthalate) (PET) films, PET films coated with SiO x and SiO x -coated PET films laminated onto low density polyethylene (LDPE) film were determined for methylethylketone (MEK) at 25 C, 35 C and 45 C using the permeation cell/gas chromatography method. Permeation of O 2 and water vapor were also determined to monitor overall changes in the barrier properties of the experimental films. Results showed that the SiO x coating increased the film barrier to MEK by 7-8 times at 25 C. The barrier to oxygen and water vapor increased by 40 and 7-8 times respectively after coating at the same temperature. Increase in temperature by 10 C resulted in a ten fold increase in permeation rate of MEK and a two fold increase in oxygen and water vapor permeation rate. Permeation values showed slight variation indicating the need for further development and standardization of the SiO x web coating process. The web coating speed did not seem to influence the barrier properties of the films. Permeation coefficient, diffusion coefficient, solubility coefficient and activation energy values for permeation were calculated for all samples.KEY WORDS Permeation / SiO x -coated PET / Methylethylketone / Barrier properties of plastics to gases (O 2 , CO 2 , N 2 ), water vapor and organic vapors are of utmost importance in food packaging applications where the packaged product's sensitivity to oxygen, water vapor and loss or pick up of odorous compounds determines product quality and shelf life. Such food packaging applications include snacks, dried soups and sauces, edible fats, coffee and baked goods but also lightly processed meat and fish packaged under modified atmospheres. 1-5The permeation properties of polymer packaging materials are influenced by (a) compositional variables such as chemical composition of the packaging material and permeant, morphology of the polymer, concentration of the permeant, presence of co-permeant and (b) environmental and geometric factors such as temperature, light, relative humidity and packaging geometry. All these factors must be taken into account when designing a particular package system. 6 Whereas extensive work has been carried out on permeation of gases and water vapor through polymeric packaging materials, permeation data on volatile organic compounds are rather limited. 5,7-11 Even more scarce is data on the effect of environmental factors (temperature and relative humidity) on the permeation of organic vapors through plastics packaging materials. 12-15Contemporary high barrier flexible packaging materials include laminated, coextruded and aluminumcoated structures using vacuum-coating techniques.Recently transparent flexible high barrier packaging materials have been developed based on SiO x deposition on films such as poly(ethylene terephthalate) PET, oriented polypropylene (OPP) and oriented polyamide (OPA). 5,[16][17][18] Typically, SiO is sublimed from the solid state and the SiO vapor is oxidized in a controlled reactive atmos...
