Many food companies are developing nanotechnology modified food packages and it is critical to understand the informational and attitudinal factors that influence public acceptance of nano-packaging. This study uses experimental auction with real nano-packaged products to test and compare consumer acceptance for nano-packaged food products with information from various sources. The results indicate when provided with information from different sources, consumer acceptance for and attitude toward nano-packaged food products are changing: for plain-labeled food products, reliance on government regulation was the only determinant influencing participants’ willingness to pay; after general information about nanotechnology was given, participants were willing to pay more for nano-packaged products, which was affected by their general attitude towards new food technology and concerns about environment/health; when detailed information were provided, concern about the environment/health became the only factor that significantly influenced participant willingness to pay for nano-packaged food products.
