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.
纳米技术有潜力创造新的食品和新的食品包装。在瑞士德语区的一项邮件调查中，研究了普通民众（N = 337）对19种纳米技术应用的看法。目的是确定更有可能被公众接受和不太可能被公众接受的食品应用。采用了心理测量范式，并在简短的情景中描述了各种应用。结果表明，情感和感知控制是影响风险和益处认知的重要因素。纳米技术食品包装被认为比纳米技术食品问题更少。对个体数据的分析表明，食品天然性的重要性和信任是影响纳米技术食品和纳米技术食品包装的感知风险和感知益处的重要因素。
