The ability to use nanotechnology will allow food companies to design and provide food products that would be safer, cheaper, and more sustainable than the foods today. Food companies will also use less water and chemicals in the preparation and production of food products.
One food company had developed nanosensors that would be embedded in food packaging. A color change in the nanosensor would alert the consumer if a food in the package had become contaminated or if it had begun to spoil. Some companies are producing a plastic consisting of clay nanoparticles. The nanoparticles in the plastic are able to block out oxygen, carbon dioxide, and moisture from spoiling fresh meats and other foods. See Chapter 7 for more information about food and agriculture.
