Nanotechnology is an enabling technology utilising the specific properties of structuring nanometer sized particles. Food production is one of many areas were nanotechnology is being developed for use, from crop fertiliser to designer drinks.

Food packaging is one area where nanotechnology is already being used. Although many of the substances used in food production are known and tested for safety in their macro-forms, the potentially adverse effects from the nanoforms can not be predicted or derived from other data. The markedly increased surface area compared to larger particles, increased exposure levels and new routes of exposure are some of the main issues in evaluating the risk from nanoparticles. We are interested in developing risk based approaches that will allow development of risk assessment methods for nano-materials used in food. Food-nano-packaging will be used as an example for a consumer exposure route to nanoparticles via the food system.
