Freeze-drying, also known as lyophilization, is a process where water is removed from a product after it is frozen and placed under a vacuum. This allows the ice to change directly from a solid to a vapor without going through a liquid phase, thus keeping the food preserved with all their nutritional values.

The beauty of freeze-dried products is that there is no need for preservatives. The lyophilisation process naturally preserves the product without artificial additives. This process also helps in preserving the flavor, color, and shape of the fruit or berry.

Freeze-dried fruits and berries can last for multiple years if stored properly in airtight containers and kept in a cool, dry place. Exposure to air, light, and moisture can reduce their shelf life.

Yes, freeze-dried fruits and berries retain most of the nutrients of fresh fruits. This includes vitamins, minerals, and antioxidants, making them a healthy snack option.

Freeze-dried fruits and berries maintain their original flavor (sometimes can even become concentrated), but the texture is different. They are overall more crunchy rather than juicy.
