From field to table
Nanotechnology can be used in the food industry right from field to table. For example, nanomaterials could help keep food fresh for longer.
Meat and cheese are often packed in protective wrappings that stop them drying out, spoiling or tainting other foods. The best packaging lets in the least air. Now nanotechnology can make this barrier twice as good. When mixed with plastic, tiny platelets only a few nanometres thick form a maze which air takes a long time to get through.
