New technology to transport fresh food long distances by boat | NHK. A major Japanese trading company has put into practical use a "dream container" that keeps fresh food fresh even if it takes a long time to transport.
The interior of the container is kept at sub-zero room temperature. By applying a voltage to it, a state called an ``electric field'' is created. Then, the water molecules inside the food become electrically charged and rotate. The company claims that this new technology can double or triple the length of chilled transportation for many foods.
