What is Freeze Dried? All the Details of Freeze Drying Technology
Today, interest in healthy, natural, and long-lasting foods is growing daily. One of the most prominent modern methods in this regard is freeze- drying technology . This method allows many foods, from fruits and vegetables to ready-made meals and plant-based products, to be stored for extended periods without losing their nutritional value.
So, what is freeze-dried and why is it so popular? Here are the details...
What is Freeze Dry?
Freeze-drying is a special preservation method that involves first freezing foods and then drying them under vacuum. This technology, known as freeze-drying in Turkish, works on the principle of sublimation, where water converts directly from ice to vapor.
During this process:
-
The water in the food evaporates
-
Vitamins and minerals are preserved
-
Natural color and aroma are not lost
-
The product lasts a long time without the use of additives
The result is a light, crispy and natural product.
How to Make Freeze Dried Products?
The freeze-drying process consists of three basic stages:
1️⃣ Fast Freezing
The product is frozen in a short time at very low temperatures.
This stage does not disrupt the cell structure of the product.
2️⃣ Vacuuming and Sublimation
The frozen fruit or food is taken into the vacuum chamber.
Here, ice turns directly into vapor without passing into liquid state.
All moisture is gently removed.
3️⃣ Drying and Stabilization
The remaining moisture is removed, making the product completely dry and durable.
These processes can be applied to many products, from fruits such as strawberries, bananas, apples to vegetables, coffee and even full meals.
