Perceived risks and perceived benefits of different nanotechnology foods and nanotechnology food packaging.
Nanotechnology has the potential to generate new food products and new food packaging. In a mail survey in the German speaking part of Switzerland, lay people's (N=337) perceptions of 19 nanotechnology applications were examined. The goal was to identify food applications that are more likely and food applications that are less likely to be accepted by the public. The psychometric paradigm was employed, and applications were described in short scenarios. Results suggest that affect and perceived control are important factors influencing risk and benefit perception. Nanotechnology food packaging was assessed as less problematic than nanotechnology foods. Analyses of individual data showed that the importance of naturalness in food products and trust were significant factors influencing the perceived risk and the perceived benefit of nanotechnology foods and nanotechnology food packaging.
