Freeze-dried fruits show unique value in the field of special diets. As space food for astronauts, freeze-dried fruits solve the dual challenges of liquid management and nutrient supply in a weightless environment.

With the accelerated pace of modern life and the improvement of health awareness, consumers are increasingly demanding convenient and nutritious foods. As an innovative product of food processing technology, freeze-dried fruit perfectly combines the nutritional value of fruit with the convenience of long-term storage, and has received widespread attention from the market in recent years. Freeze-drying technology originated in the medical field in the early 20th century and was gradually applied to food processing, especially the processing of heat-sensitive nutritious foods. Compared with traditional drying methods, freeze-drying technology can remove moisture at low temperatures and retain the original nutrients, color, flavor and shape of fruits to the maximum extent.
