Since it does not increase the heat of food products, it does not inflict the damages caused by heat; it protects the outer appearances, colors, textures, tastes, aromas of foods.
Compared to the conventional drying methods, the rate of the residual moisture at the end of the process is 1-2% lower.
The rate at which the rehydrated cells enliven is very high and the damage they incur is low, the rehydrated food become fresh again.
The weights of foods, freshness qualities of which are protected through lyophilization, are lower at the proportion of 1 in 10 in average.
The products that are packaged in a protective way can endure very long time at normal ambient temperatures without degradation.
Since it does not keep the materials at very low temperatures for long time, it has few adverse effects caused by freezing stress. Wet papers, fabrics and wood-like materials are competently dried.
Allows liquids (such as drugs, vaccines etc.) to be processed in their final containers.
The rehydrated foods become fresh again.
In lyophilization, the roasting effect caused by hot air in drying with hot air does not occur.
All these advantages, rehydration of the materials take place easily, quickly and smoothly.
As for in the rehydration of the sensitive materials, isotonic water and some auxiliary solvents are used.
These types of auxiliaries are used also for regenerating the material containing living cells such as bacteria.
In this respect, it is better than hot air drying and canning.
Flowers retain their vibrant appearances for a very long time.
This period is sometimes expressed as 30 years in case of foods.
It yields high quality product.
Vitamin and mineral loss is minimal.
No change occurs in the shape and dimensions of the product.
The expelled water can be regained.
The shelf life of the lyophilized food products is approximately as follows:
Vegetables, fruits, pastry foods, milk: 8-10 years
Sprouted seeds, sauces, seasonings, meats: 5-10 years
Eggs and cheese dusts: more than 5 years
Meals: 1-5 years
Cereals, beans, peas: 10-15 years
