The process requires that typically the fresh or prepared food be quickly frozen at temperature ranges just -50�C. Typically the frozen food will be then include in a new vacuum chamber. This kind of vacuum chamber lowers the pressure, and raises the temp in order to about 0�C.
At this specific heat and pressure, typically the ice crystals in the food evaporate into water steam, bypassing water's water form, through some sort of process called sublimation.
This procedure preserves typically the cell structure and even nutritional content regarding the food, causing in a product or service that, when rehydrated, extremely closely resembles typically the original food.
The particular process also prevents the water by being reabsorbed by the food and therefore decreases the weight considerably.
Most food products such as fruits, greens and meats are well-suited to freeze-drying, and can turn out to be used for long term food storage plus preservation.
The Process of Lacks
Dehydrating food is a food preservation method which has been used for decades. Native Americans dehydrated their buffalo kills throughout their hunting camps to make that better to transport. Pemmican (a dehydrated mixture of buffalo beef mixed with fat and berries) was a new staple of countless of the nomadic United states tribes.

The obvious benefit is definitely that since the particular meal was ready in its entirety prior to freeze-drying, most you need to do is merely add water, next heat for a new few minutes in order to create sumptuous foods.
Rehydrating freeze-dried foods takes just some sort of few minutes, basically by adding boiling water. Some foods, love many fruits plus vegetables, need simply no re-hydration before ingesting.
Dehydrated tarif traiteur shrink during processing while the moisture will be removed. Hence the meals item itself is usually considerably smaller compared to its original sizing.
The re-hydration time of dehydrated meals takes a bit longer than freeze-dried, but it photos tastes like the original kind of the particular food. Some dehydrated foods contain extra ingredients to enhance flavors or aid in preservation. As with freeze-dried fruit and veggies, dehydrated fruits plus vegetables can be enjoyed without any re-hydration.
Both methods associated with food preservation boost the long-term storage area life of foods. Most commercially made freeze-dried and dehydrated foods have a shelf life of 15 to 20 years, if properly packaged and trapped in a cool, free of moisture environment.
In improvement to their being a reliable source of food in an emergency or long term survival scenario, due to the fact of their gentle weight and relieve of portability, these food types are also great for accepting camping, trekking and hunting outings.

Which in turn Type is Enhanced for Consumption?
Everyone is different, and each person has their very own own personal tastes and even preferences. With that in mind, generally there are a several facts to consider before generating a decision among freeze-dried or dehydrated food.
Home-grown vegetables and fruit are better preserved through dehydration, since the average person cannot afford the costly machinery found in freeze-drying.
Foods utilized in everyday preparing and meal preparing should probably be freeze-dried. This enables the food being quickly re-hydrated since it is cooked prior to serving. If convenience and portability will be important, than both type of stored food should satisfy those particular requires. Once again, really a matter of personal personal preferences.
In a nutshell, both dehydrated and freeze-dried foods are generally excellent options for long term food storage, since well as for daily use or perhaps for hiking, camping, etc. They equally provide light-weight, portable, convenient foods.
