Migration from non-ovenable food contact materials at elevated temperatures.
… development of complex polymeric materials for food contact applications is the potential for migration of toxic substances from the polymer to the food. This thesis investigates the transfer of migrants from non-ovenable food contact materials at elevated temperatures, and several applications …

Development of Multi-layer Films Containing Natural Antimicrobial Agents
… required to provide the optimum AM effect in food media and on Cheddar cheese was explored. The stability of the AM coatings in various food simulants was also explored. In the film preparation, the AM coatings were embedded between low-density polyethylene (LDPE) layers to construct …

The effect of structure on the mass transport of acetaldehyde in virgin and recycled poly(ethylene terephthalate)
… PET bottles are extensively used for various food-packaging applications, particularly in developed countries, which is leading to disposal problems. Presently, there is an increasing emphasis throughout the world to recycle PET. The use of recycled PET for food packaging applications however, …

THE RELEASE OF CONTAMINANTS BY LEACHING FROM BOIL-IN BAG LAMINATES
… of polymeric multilayer laminates for packaging food, relates to the migration of potentially toxic substances from the packaging material into the food. These contaminants can originate from the non-food contact layer and/or from the laminate adhesive. This thesis investigates the nature, …

Development of LDPE-based antimicrobial films for food packaging
… microorganisms that may contaminate packaged food products. Over the years there has been an increased emphasis on naturally derived AM agents and polymer films containing AM agents derived from basil, for example, exhibit an AM effect against a wide spectrum of microorganisms. Due to the …

Biodegradable food packaging using agricultural wastes (Banana Pseudostem)
Biodegradable food packaging has been developed in this research from banana pseudostem. The research can be divided into three phases. The first phase was to explore the possible method to isolate nanocellulose from banana pseudostem as the main polymer for bioplastic formation. Alkaline …

Migration of additives from thermoplastic polymers
… migration from LDPE into various solvents and food simulants was studied at temperatures 5, 23, 40 and 70oC; from the plots of rate of migration versus square root time, characteristic diffusion coefficients were obtained by using the solution of Fick's diffusion equations. It was shown that …

Φασματοσκοπικός έλεγχος ενδεχόμενης αποδέσμευσης (νανο)υλικών από βιοπολυμερικές συσκευασίες σε προσομοιωτές τροφίμων
Σήμερα, χρησιμοποιούνται σε μεγάλη κλίμακα τα πλαστικά για τη συσκευασία διαφόρων τροφίμων, φαρμάκων και καλλυντικών. Ωστόσο, όπου υπάρχει άμεση επαφή μεταξύ του συσκευασμένου προϊόντος και της πλαστικής συσκευασίας, υπάρχει πιθανότητα να πραγματοποιηθεί κάποια μετανάστευση από το πλαστικό στο …
