Results of the TA-SWISS study "Nanotechnology in the food sector" |
|
More attractive, fresher, healthier −
thanks to nano-packaging and nano-additives? Bern, 23 January 2009. Nanotechnology is moving into the food industry, in the form of additives or in packaging materials. A study by the Centre for Technology Assessment TA-SWISS provides an overview of nanomaterials already used in the food sector. The study assesses these products in respect of environmental issues and sustainability, showing the direction that future developments might take and where there is a need for caution. |
