MIGRATION PROCESS OF SOME CHEMICALS IDENTIFIED THROUGH FOOD PACKAGING FT-IR ANALYSIS

摘要

The EU legislation determines the limits of some chemicals: polymers, monomers and additives as ingredient of plastic packaging materials for contact with food. The absence of specific legislation and the obligation to control the composition of food packaging in Kosovo has negatively caused possible usage of a high percentage of recycling materials for contact with food, uncontrolled materials that do not meet the standards and non-recognition of those materials by users and consumers, which could pose a risk to food safety and consumer. To demonstrate the non-compliance of a type material or kind article, it is obligatory to confirm the estimated migration value by experimental testing. A strict control from the governmental authority is needed to supervise packaged plastic materials used widely at Kosovo market, in order to stop to overpass the compromise values of recycled plastic for food packaging, and special measure needs to be taken for improving our national legislation for the concerning problems. Through the migration process evaluation except use of different specialised software and different modelling which have been scientifically verified and mathematical calculations, we were able to perform some experimental measurements using instrumental analytical method of FT-IR in order to complement knowledge and improving the understanding of migration which makes possible prediction and calculation of the life time limit of food storage in some packages.
