Fruits & Vegetables 

Freeze drying, also known as lyophilisation or cryodesiccation, is a low temperature dehydration process which involves freezing the product, lowering pressure, then removing the ice by sublimation. This is in contrast to dehydration by most conventional methods that evaporate water using heat.

Freeze drying results in a high quality product because of the low temperature used in the process. The original shape of the product is maintained and quality of the rehydrated product is excellent.

Freeze drying of food

Examples in the food segments include:

  • All fruits (berries, slices of apples, bananas, mangoes, pineapple, apricot, melon etc.)
  • Vegetables. (chilies, onions, peppers, garlic, coconut, coconut flour etc.)
  • Whole meals (stews, spaghetti w. meat balls, gullash, chili con carne, pulled pork etc.)
