Since dirt tare became a factor in the beet price in 1988, growers in Denmark have been urged to intensify mechanical cleaning at the risk of extra damage to the roots and hence greater postharvest losses. In studies from 1988 to 1994, sugar losses by respiration, mechanical damage and leaching during washing were determined in mechanically harvested beet classified according to the extent of injury. Mechanical losses were often the greatest, typically 3% from root breakage and 11% from overtopping. Respiration in slightly injured beet caused losses of 0.7-0.8% after 1 week of storage and 2.25% after 6 weeks; the figures were 10-20% higher for severely injured beet. Loss in washing was 1.0-1.3% for slightly injured beet, or up to 50% higher for overtopped or severely injured.
