Freeze-drying: A modern method for preserving food

I have had so many people say that freeze-drying is not raw.

A common misconception, however, in short, freeze-dried food is still raw because the process uses cold temperatures to remove moisture. It is never cooked or heated, so all the raw nutrients and enzymes remain intact. The only difference between our freeze-dried and frozen raw food is the water content, which is what makes it so convenient for storage and travel!

Freeze-drying is a process that removes water from food through sublimation. This is a process in which water turns from a solid (ice) to a gas (vapor) without first becoming a liquid. Freeze-drying is a popular method for preserving food because it can help to extend the shelf life of food and preserve its nutrients.

How does freeze-drying work?

The freeze-drying process begins by freezing the food. The food is then placed in a vacuum chamber and the pressure is lowered. This causes the ice in the food to sublimate, leaving behind a dry, porous product.

Benefits of freeze-drying

There are many benefits to freeze-drying food. One benefit is that it can help to extend the shelf life of food. Freeze-dried food can be stored for up to two years without losing its quality.

Another benefit of freeze-drying is that it can help to preserve the nutrients in food. Freeze-drying does not use heat, so it does not destroy the vitamins and minerals in food.

Freeze-drying is also a good way to reduce the weight and volume of food. This can make it easier to transport and store food.

How is freeze-dried food used?

Freeze-dried food is used in a variety of applications. It is a popular food for camping and hiking because it is lightweight and easy to prepare. Freeze-dried food is also used in the military and other emergency situations.

Conclusion

Freeze-drying is a versatile and effective method for preserving food. It can help to extend the shelf life of food, preserve its nutrients, and reduce its weight and volume. Freeze-dried food is a popular choice for camping, hiking, and other outdoor activities.
