Aluminum foil container in microwave ovens is safe

24 Nov, 2022

Conclusive evidence that aluminium foil packaging can be used safely in microwave ovens has been established by a study from the Fraunhofer Institute for Process Engineering and Packaging IVV in Freising, Germany. The results dispel the myth that aluminium foil containers are unsafe for use in microwave ovens and prove that consumer fears about using alufoil packs in the microwave are unfounded. In fact in some instances consumer convenience is improved as not only are alufoil packs more rigid, something that is equally applicable to dual-ovenable containers, the use of aluminium foil enhances the appearance of the food when heated in the microwave oven. For example the study found that in the case of lasagne heated in a microwave oven its visual appearance was superior as abrown crust was formed on the surface.

Four kitchen microwave ovens were used to test aluminium foil trays containing tap water, egg batter, frozen lasagne and minced meat. Tests were also conducted on plastic cups and plastic trays containing a noodle soup and a children’s menu, covered with either aluminium foil or aluminium laminate lid. The study found some differences in the time needed to heat products when aluminium foil containers were compared with plastic trays. Due to variations in heating patterns and depending on tray geometry and food type, heating times for aluminium foil packs were sometimes longer. However, observed Pfeiffer, “The study also provides some interesting results regarding heating patterns and heating uniformity. In some cases they appeared to be better in aluminium foil trays.”
