The terms “dehydrated food” and “freeze dried food” are frequently confused, however they are not equivalent. When it comes to determining how to store and preserve food for your household, understanding the differences is essential.

Freeze dried food

Food preservation via freeze-drying is a relatively new technique. It involves freezing the food, then utilizing a vacuum chamber to remove nearly all of the moisture before sealing it in an airtight container. Freeze dried foods are easy to carry at room temperature, can be store for a long time, and require little preparation. Once cooked, freeze-dried foods have a comparable appearance and taste to the original, natural products.

Dehydrated food

Food dehydration is the process of adding one or more types of energy to food in order to lower moisture levels to low levels in order to extend its shelf life. However, mechanical pressing of food to eliminate moisture or the concentration of liquid meals are not include.

Difference b/w Both

Freeze dried food	Dehydrated food
All liquid is removed, resulting in a crisp, airy texture with a high shelf life.	Moisture is retained, resulting in a product that is softer and chewier and has a shorter shelf life.
The appearance of the foods is kept as near to the original as possible.	Foods shrivel and lose their attractiveness.
In most cases, the flavor stays similar to the original.	Flavors change, and they aren’t always authentic to the original.
Can be rehydrated to a state that is close to or identical to the original.	It is not possible to rehydrate it to its original state.
Before drying, it flash-freezes to preserve the nutrients.	Heat is used to dry the food, which reduces the nutritional value.
You can only dehydrate a limited number of foods.	Almost anything can be frozen dried (with the exception of meals with a high fat content, such as butter, or foods with a high sugar content, such as honey).

Is Freeze dried better?

Variety is maybe the best reason for freeze drying. Freeze drying can be use to preserve and store almost any food. Meats, fruits, veggies, sweets, and even whole dinners are all available. Freeze-dried foods, meats, dairy, eggs, and vegetables all recover quickly, sometimes almost instantly.

Dry cottage cheese, as well as sour cream, can be froze and store without refrigeration. Eggs scrambled with cheese? It’s no problem! The best approach to preserve and keep dairy and eggs is to freeze dry them. Dehydrating these items, on the other hand, is extremely difficult.

Conclusion

Freeze-dried foods have a longer shelf life, contain less moisture, and have a better flavour than dehydrated goods. Foods that have been freeze-dried rehydrate quickly and preserve their original shape, texture, and colour. Freeze drying allows you to freeze a far wider range of items than dehydrating. Consider attempting to dehydrate an ice cream sandwich, a raw egg, or cheese using a home dehydrator. It would be a colossal failure. If freeze-dried, this is not the case.
