What is the best and safest food preservation method? What is Freeze-Drying?

FREEZE-DRYING - the best and safest food preservation for consumers

After learning more about freeze-drying, only I came to know there are so many benefits of freeze-dried food. I appreciate all the manufacturers in providing freeze-dried food for people. 

Freeze drying is a relatively recent method of preserving food. It involves freezing the food, then removing almost all the moisture in a vacuum chamber, and finally sealing the food in an airtight container. 

Freeze dried foods can be easily transported at normal temperatures, stored for a long period of time, and consumed with a minimum of preparation. Once prepared, freeze-dried foods have much the same look and taste as the original, natural products.




The freeze-drying process was developed during World War II as a method of preserving blood plasma for battlefield emergencies without requiring refrigeration or damaging the organic nature of the plasma. 

The technology was applied to consumer food products after the end of the war. Coffee was one of the first freeze-dried products to be marketed on a large scale. Today, many fruits, vegetables, meats, eggs, and food flavorings are freeze-dried.

Freeze-drying has several advantages over other food preservation methods. 

  1. Frozen foods retain flesh flavor and nutritional values, BUT require uniform, low temperature storage. 
  2. Dehydrated and canned foods are shelf-stable, BUT high-temperature processing can degrade flavour, texture and nutritional content. 
  3. Freeze-drying combines the best of these processing methods. It preserves the WHOLESOMENESS, FRESHNESS, COLOR and AROMA similar to frozen food, while providing the shelf-stable convenience of canned or dehydrated food. 
  • Taste fresh. Freeze-driein virtually all their fresh-food taste and nutritional content. Freeze-drying removes the water, not the taste and flavour.
  • Look fresh. Freeze-dried foods maintain their WHOLESOMENESS, original shape, colour and texture, unlike dehydrated foods, which shrink and shrivel due to high-temperature processing. Freeze-drying removes water under low temperatures (typically a maximum of 100 to 130 degrees F), which keeps intact the moisture channels and food fibers. Just add water, and in minutes every fresh food detail returns.
  • Safer. Freeze-dried food is also relatively contamination-free since the dehydration process makes it virtually impossible for yeast and potentially harmful bacteria to survive.
  • Weigh less than fresh. Freeze-dried foods have 98% of their water removed. This reduces the food's weight by about 90%. 
  • Stay fresh. Freeze-dried foods can be stored at room temperature, without deterioration or spoilage. This is because freeze-drying and packaging remove both water and oxygen - the two primary causes of food deterioration.

So, Why E.Excel food products are wholesome plant foods products - although appear in sachet forms?

Because they are FREEZE-DRIED food, hence can be kept longer without adding any preservatives and yet the wholesomeness, and nutritional values are maintained as that in original plant foods.

I value wholesome food personally, with freeze-dried food, it has further added value of convenience to me in getting healthy wholesome food.
