Nanopack is an international project aimed at creating a new food packaging, using nanoparti-cles. The new food packaging is designed to reduce microbial activity, prolong food shelf life and reduce the use of preservatives. The purpose of this project is to investigate the toxicity of the chosen nanoparticles NaturalNano, NaturalNano etched and NaturalNano etched & silanized on Muta mouse ™ lung epithelial cells (MML) compared to the positive control zinc oxide. The group´s results along with Det Nationale Forskningscenter For Arbejdsmiljø (NFA), aim to show the possible dangers that the production of the new food packaging could cause. Other studies on nanoparticles have shown varying results, with some nanoparticles showing toxicity while others do not. To investigate the toxicity of the used nanoparticles, we performed an in vitro assay. The results showed that NaturalNano etched & silanized exhibited the lowest toxicity whereas NaturalNano and NaturalNano etched exhibited varying toxicity with varying standard deviations. The positive control zinc oxide showed high mortality on MML cells as expected. The results of NFA’s in vitro assay did not exhibit toxicity compared with our results. Due to our high standard deviations and varying results it is not possi-ble to conclude whether the three nanoparticles are toxic.
