Would you like to know what is the difference between frozen dry food and dehydrated food?
There are many differences.
First, the process of preserving food and preventing corruption and enzyme decomposition is very different.
Other factors you may want to consider are cost, shelf life, taste, texture and nutritional value.
Dehydration removes moisture from food through the circulation of hot dry air.
The water evaporated.
This prevents the growth of microorganisms.
Oxygen, heat, light and moisture all contribute to the decomposition of nutrients and corruption of food.
Due to the use of heat, some nutritional value will be lost.
Using an electric dehydrator can save more nutrients than some other dehydration methods.
Dehydrated food is lighter than frozen and dry food, and the price is generally lower.
However, it does change more in texture, aroma, taste and nutritional value.
When stored, it can have a shelf life of up to 12 years. Re-
In boiling water, the hydration time is usually up to 20 minutes and can be up to two hours in cold water.
Freeze-drying removes moisture from food by sublimation.
The food is sealed in a vacuum chamber, forcing the air out.
Freeze and dry use-temperature
50 degrees Celsius and-
80 degrees Celsius.
This evaporated the ice.
As a result, frozen-dried foods retain more nutrients, as well as most of the original aromas, textures and flavors.
Freeze-dried foods are lighter and often more expensive than dehydrated foods.
The process can take a few days and the equipment is expensive.
The shelf life of freeze-dried foods is longer than that of dehydrated foods because up to 98% of moisture is removed.
Shelf life can be up to 25 years if stored properly. Re-
The hydration time in hot water is generally 5 minutes, and the hydration time in cold water is up to 10 minutes.
Dehydrated and freeze-dried food is light weight and easy to prepare and is perfect for back packaging.
They are all great for long-term food storage.
Both reduce the waste of throwing away spoiled fresh produce.
However, if nutritional value and taste are your top priority, then I would recommend that you choose to freeze and dry food instead of dehydrated food.
The taste, texture and fragrance are good every time.
I find it cheaper to store the food your family will eat in the long run.
You don't save money by buying something cheap that they won't eat.
