It is not unusual for a long life food supply to be valid for upto 25 years, and will retain most of its flavour, quality and nutritional value. There are several methods used to produce long life food but the most popular are Freeze Drying or dehydration. You may not have heard of these processes but many of the products that you find in your supermarket may utilize this method. There is a vast assortment of gourmet food entrees, breakfast and desert that can be reconstituted ready to prepare in minutes.
Process for Freeze Drying
In freeze-drying, the product is first flash frozen and then placed in a vacuum drying chamber. The colour, shape or goodness is not affected by the removal of most of the moisture durring the drying process.
The Dehydration Process
In dehydration, food product moves through a drying chamber where air removes the moisture from the food. This occurs at low temperatures so that the nutritional profile stays intact.
Many people buy Freeze Dried Food not just in case of emergency, but to eat every day because it tastes great! Because it is lightweight it is easy to handle and can be stored in larger containers to save space. In real terms it is not expensive to buy and cheap to prepare. All you need to do is simply add water! It can even be rehydrated and then eaten with cold water in emergency situations where there is no way to heat the water. Being lightweight it is easier to transport larger quantities of freeze dried food than if they had not been dehydrated, perfect if you are on the move.
There is a huge selection of recipes already prepared but if you want to you can buy just meat or chicken, vegetables or fruit as bulk items that you can then prepare your own recipes. In today’s unsettled economic times food has increased in cost annually so food storage makes sound economic sense as a food insurance against inflation.
