FDA Proposes Rules for Nanotechnology in Food
Regulators are proposing that food companies that want to use tiny engineered particles in their packaging may have to provide extra testing data to show the products are safe.
The Food and Drug Administration issued tentative guidelines Friday for food and cosmetic companies interested in using nanoparticles, which are measured in billionths of a meter. Nanoscale materials are generally less than 100 nanometers in diameter. A sheet of paper, in comparison, is 100,000 nanometers thick. A human hair is 80,000 nanometers thick.
