New Light Technology Helps Improve Food Safety

Newswise — CHICAGO— Light-based technologies are emerging as tools to enhance food shelf life and guard against food contaminants but more research needs to be done, warn food scientists at a July 13 panel discussion at IFT15: Where Science Feeds Innovation hosted by the Institute of Food Technologists (IFT) in Chicago.

The use of ultraviolet light, pulsed light and LED lights are being studied by food technologists as a new way to improve food longevity and assist in eliminating bacteria from such food products as milk and juices. However, scientists warn they need to learn more about how these light rays penetrate foods at varying degrees to ensure food safety.
