NANOFOODS: Coming Soon to a Fridge Near You! David Berube - Professor of Communication with a focus in Science and Technology, NC State University 7pm Cold beer, Hot food, Cool Science. Fan us on

Communicating Risk to the Public  Written extensively in the rhetoric of emerging technologies, esp. nanotechnology (including NanoHype: The Truth Behind the Nanotechnology Buzz. NY: Prometheus Books. 2006).  Four recent publications:  Journal of Nanoparticle Research.  Nanomedicine and Nanobiotechnology.  Nanotoxicology.  Nanotechnology Law and Business.  Consult in risk and crisis communication with trade organizations, marketing groups, and industries, including the prepared food industry.

WHAT IS NANOTECHNOLOGY?

SIZE

WHEN DID NANO START?

NANO-GRAFITTI

WHO DOES NANO RESEARCH?

WHY NANO?  Bioavailability (surface area).  Efficiency (reduce resource).  Environment (Green Nano).

SURFACE AREA  Rubik’s Cube (inches). 6 surfaces (3 x 3). 27 cubes (1 x 1). 54 square inches.  27 separate cubes. 6 surfaces (1 x 1). 6 square inches. 6 x 27 = 162 square inches.

FOOD

APPLICATIONS?  Nano-emulsions and nano-capsules in Production – Smart Farming. ○ Agricultural chemicals. ○ Piping and plastics. ○ Sensors (field sensors = smart farming). Processed or prepared foods. ○ Nutritional additives (co-enzyme Q10, Omega 3). ○ Preservatives. ○ Colorants and flavorants. ○ Accidental contaminants from wear.

APPLICATIONS (CONT.) Food packaging. ○ Adhesives. ○ Antibacterial ingredients. ○ Surveillance materials. Anti-counterfeiting. Detecting pathogens. Food contact materials. ○ Storage containers. ○ Cutlery. ○ Chopping boards

RECOMMENDATIONS 1. Regulate as new substances. 2. Size-based definition must be extended from 100nm to at least 300nm. 3. Relevant data should be placed in the public domain. 4. Ingredients must be clearly indicated on labels. 5. Public involvement in decision-making.

CATEGORIES  Alumina silicate – anti-caking agent.  Silver – antibacterial.  Silicon dioxide – mineral (bone health).  Titanium dioxide – whitener.  Zinc – mineral (immune).  Zinc oxide – antibacterial and whitener.

IS NANO SAFE?
