2. Size Nano is 10^-9 compared to the base in the SI units 10 micrometers 10^-6 is width of red blood cell 10 nanometers is the width of a cell membrane 1nanometer is about the size of a sugar molecule 2 Sugar Red Blood Cell www.understandingnano.com

3. Nano and Food Food Storage Nutrition Fighting Contaminants 3 www.understandingnano.com

4. Food Storage Clay Nano composites - made by dispersing a nanoclay into a host polymer -also called exfoliation -Nano composites are better barriers, more flame resistant, structurally strong -impermeable to gases and liquids 4 www.understandingnano.com

5. Food Storage Silver Particles -silver has been proven to fight mold and fungus on a microscopic level -antimicrobial nanoparticles in the polypropylene material of the container reduce growth of microorganisms 5 www.understandingnano.com

6. Food Storage Zinc Oxide Nanoparticles -put into plastic film and improves strength and stability -blocks UV rays -fights bacteria 6 www.understandingnano.com

7. Nutrition Nano capsules in Food -Nano capsules that contain vitamins or other nutrients infused into food -capsules would release nutrients if digested or by nanosenor in the body -would be useful in storage of vitamins in the human body -this is still in research 7 www.understandingnano.com

8. Fighting Contaminants Nano Sensors -nano sensor that could detect food contaminants in 15 min. -regularly could take 24 hours to detect contaminants -detects contaminants such as salmonella, e coli, or listeria 8 www.understandingnano.com

9. Fighting Contaminants Pesticides -nano capsules are being researched to carry pesticides directly to the insects -the insect would ingest the nano capsule that was on the plant and once inside the insect it would kill it -this would cause less contamination to the plants themselves 9 www.understandingnano.com

10. Outlook Sharper Image - Is coming out with a new silver nano particle container called Fresher Longer Miracle Food Storage Containers 10 www.understandingnano.com

11. Outlook Nano Sensors -NSD (Nano Science Diagnostics) is developing sensors that detect food contamination in only 15 min. -traditionally it takes at least 24 hours to detect a food contamination -these nano sensors are being developed in a kit, cartridge, and a hand held instrument www.understandingnano.com 11 www.foodproductiondaily.com Ahmed Elamia

12. Outlook The storage products using nano technology are much farther along The nano sensor is in testing phase The nano capsules for pesticides and nutrition are still being researched 12 www.understandingnano.com

13. Conclusion Nano technology can greatly help the food industry by creating safer, healthy storage devices. Nano technology can also help fight against food contamination. 13 www.understandingnano.com
