Spørgsmål angående migration af kemiske stoffer ved opvarmning af emballeret skolemad i US
DTU Fødevareinstituttet har fået en henvendelse fra en amerikansk journalist, som er interesseret i opvarmning af færdigpakket mad i amerikanske skoler. Journalisten spørger om følgende:
- Are there any concerns regarding the transfer of toxic chemicals to the food, when it is heated up in what manufactures call “ovenable” pouches or films?
- Or are these particular plastics indeed safely used in ovens and not a cause for worry?
Svar:
Plastic packaging used for food contact shall comply with the EU regulation 10/2011 which require that only evaluated substances on the positive list in this regulation are used.
As migration increase with increased temperature of contact, compliance testing by industry of pack- aging materials for ovenable use should always include worst case test conditions of temperature and contact of use. Moreover, from literature it is reported that degradation of chemical substances in the plastic may occur at high temperatures producing non intentionally added substances (NIAS).
Unfortunately, we do not have specific data on “ovenable” pouches or films and their potential migra- tion of chemicals to the food. Also, we do not know how much these kinds of food are used by Danish school children and teens and thereby their potential chemical exposure from such materials. How- ever, there is an increase in the convenience food market and it might be interesting to look closer into the food safety of such materials.
