The benefits of freeze dried food are quite diverse. War usually stimulates innovation. In fact, it does so in unexpected ways that span a range of industries. The food industry is no exception to this rule. During World War II, there were many developments in food processing, food distribution and food preservation. One key breakthrough that is still with us today is freeze drying. Freeze drying has its origins not in food originally but in medicine, as it was used to maintain and preserve serum. However, it wasn’t long before the value of freeze drying was realized for food preservation. Today, freeze drying is a valuable tool regularly used by the food industry.
Food that is freeze dried undergoes four distinct steps:
2. The freezing process itself, which uses everything from mechanical refrigeration to dry ice and liquid nitrogen.
3. The drying process, which involves vacuum pressure and may last days.
4. A secondary drying process. The purpose of the secondary drying process is to remove any remaining ice.
By the end of this four step process, very little water is left in the final freeze dried food.
Benefits of Freeze Dried Food Include Preservability
One of the most striking benefits of freeze dried food is that it can last for many years. Since water levels have been reduced dramatically in the freeze drying process, food will not spoil. This means it can kept on shelves for a very long time.
Improved Taste and More Nutrition
The freeze drying process causes less damage to food than other methods and that is another key advantage. This leads to a better tasting and more desirable product. Flavors and textures are preserved. This benefit is part of why freeze dried food is wildly popular with those who are in remote locations such as hikers.
A third key reason that people gravitate towards freeze dried food is due to the increased levels of nutrition. Preserving food can reduce nutrition levels, but the freeze drying process can preserve nutrition that is often lost in other methods.
7 Key Benefits of Freeze Dried Food
-Can be placed in durable containers.
-Improved taste over other preservation methods.
-Higher levels of nutrition.
-Ease of storage.
-Ease of transport. Food can be taken almost anywhere.
-Excellent option for emergency situations.
Combining these three key factors, it is no real surprise that freeze dried food is highly regarded as a food to use in emergencies. For decades, the benefits of freeze dried foods have been clear. As a result, the freeze dried food approach has become very popular as an emergency food option.
The fact that freeze dried food can be stored for years, is easily transported, can be placed in durable packaging and maintains taste and nutrition levels helps make it an easy choice for those looking for an exceptional emergency food. The trouble free nature of freeze dried food and the fact it enjoys essentially zero maintenance makes it an easy pick for those who want a durable and long-lasting food supply on hand for years to come.
