Researchers in Sweden have developed a method of freezing fresh vegetables that preserves their firmness and taste after defrosting. The team at Lund University says their method could allow farmers to freeze their produce for sale all year round, while producing crisp and tasty pre-frozen salads every time. Jim Drury went to find out more.
