00:00 Researchers in Taiwan have come up with a new way of prolonging the shelf life of fruit,
00:04 with electromagnetic waves.
00:07 Fruit is usually preserved by freezing or adding chemical preservatives.
00:11 The researchers say using electromagnetic fields offers an improved way to freeze fruit.
00:16 Their technology has already been patented, and fruit exporters say it will give Taiwan's
00:20 fruit a competitive edge on the global market.
00:23 The researchers say their invention helps fruit retain moisture and reduces cell damage
00:27 by rearranging the molecular structure.
00:30 "Cells have many ice crystals.
00:33 Traditional freezing, whether it's fast or slow,
00:36 only makes the ice crystals smaller.
00:39 But now we can arrange the ice crystals more tightly."
