The wonderful properties of the wonderful berries and the afflictions for which it helps can be listed for a very long time. But there is a problem: fresh fruit can not be stored for long even in the refrigerator, and heat treatment leads to the loss of useful properties. Of course, the fruit can be dried, but there is little left of the delicate flavor, and the type of berries will be very unattractive.

However, today there is a way to preserve both the attractive appearance and the useful properties of the product - sublimation.

Sublimated products are beginning to be widely used in practice and gradually appear in our daily life. We have long been accustomed to the presence in our homes of such a product as freeze-dried coffee. In many countries, the presence of freeze-dried products on store shelves is no surprise to anyone.

This modern technological process allows you to keep products that were not subject to long-term storage for as long as possible.

Sublimation is a special method for removing liquid from products in a vacuum. First, fast freezing of products to a temperature of -200 ° C is carried out. It is known that during freezing, a liquid is converted into ice crystals, exceeding the volume of the liquid itself. However, during rapid freezing, the crystals are so small that they do not destroy the cell membranes. Then, in a hermetically sealed chamber, from which air is removed, the products are heated.

Ice crystals evaporate without becoming liquid. Dried products are packaged in sealed packages. They can be stored for a long time without a refrigerator. When storing it is desirable that they do not fall under direct sunlight.

Sublimated products placed in warm water quickly restore their original shape and are fully ready for use.

Sublimation as a type of canning has many advantages:

• all useful properties of products are saved;
• their shape, color, structure and even flavor are preserved;
• there are no preservatives, dyes, flavor enhancers, flavors;
• after freezing, the formation and development of fungus and harmful microorganisms do not occur;
• long shelf life.

Sublimation does not have any negative characteristics, the main thing is that the original products should be of good quality.

Since the dry product weighs very little, it is convenient to take it with you on the road. As a dietary product with valuable qualities, it is suitable for athletes, climbers, workers - all people who face in their practice with great physical exertion.

On the Internet you can find publications and videos on how to cook sublimated raspberries and other berries and fruits at home. The authors claim that the resulting dry products have excellent consumer properties, are well and long stored.

However, it should be borne in mind that at home you will not be able to ensure proper quality and reproduce the entire industrial process with strong freezing and subsequent heating in a vacuum, since this requires special equipment and high energy costs.

Here, rather, we are talking about the usual drying, and the process cannot be called “sublimation”. Dried berries will not return the original shape and color in the water. And during heat treatment they will lose a lot of useful properties, with long-term storage, insects and fungi invade them.

Recovered berries can be eaten or used to prepare various dishes. Raspberry desserts with various sauces are popular in many restaurants. Beautiful berries are often used to decorate dishes and confectionery.

Berries can be added to pancakes and pancakes, porridge and pastries. And they are also used for cakes and fruit smoothies, compotes, and pie fillings. To get the original taste of the filling, experienced housewives often mix raspberries with other fruits.

From sublimated raspberries, both dry and reconstituted, you can make ice cream. The recipe is very simple. Beat 200 grams of 30% cream with 150 grams of sugar and 50 grams of sublimated raspberries and freeze the resulting mass. Then beat another 30 grams of cream and gradually add to the frozen part. Cool and serve.

From dried berries can make powder.

The powder is also added to cereals, dough for pancakes, pies, cookies, cocktails and creams. As a flavoring, it is appropriate in ice cream, chocolate and other confectionery.

Powder as decorative powder will decorate the finished cake or cupcake. A teaspoon of powder can be simply diluted in a glass of water, and you get an original drink with a natural raspberry flavor and aroma.
