LYOPHILIZATION INTRODUCE
Freeze-drying technology is the technology of freezing materials containing water, heating in vacuum environment, so that the ice in the materials directly sublimed and dehydrated to obtain dried products. The application of freeze-drying technology to process food is called food freeze-drying, and its products are called freeze-dried products. Freeze-dried products can maximize the retention of food nutrients and flavor substances, can maintain the same shape and color as the original fresh food, without any additives can be stored at room temperature for a long time, and good rehydration.
With the development trend of "healthy and convenient" in the world food industry, the application of food freeze-dried is more and more extensive, and it is developing from special application fields such as aerospace, military, national strategic reserves and exploration to the mass market.
