The crops have been harvested. Now it is important to store the various crops well and to preserve them as long and as carefully as possible. Post-harvest losses due to spoilage, however, represent a significant problem along the supply chain and lead to profit losses in the millions. According to the FAO (Food and Agriculture Organization of the UN) statistics, almost half of the world’s harvest (45 percent) of fruits and vegetables are lost on their way to the end consumer. The main causes of these losses are pest or disease infestation and incorrect storage conditions, which lead to rotting or loss of fresh mass due to respiration and evaporation. The only remedy is often the excessive use of chemicals. Researchers from the Institute of Environmental Biotechnology at TU Graz in cooperation with the Austrian Centre of Industrial Biotechnology (acib) and industrial partners have successfully tested ecological methods that improve the storage of apples and sugar beet—representative examples for other types of fruit and vegetables.
