Locations of extraction and varieties of black caviar

The object for fishing for seafood is exclusively sturgeon fish, whose habitats are located in the Azov, White, Black and Caspian Seas, the lower reaches of the Danube, the rivers of Siberia, and less often in reservoirs in China. Due to the constant decline in the number of sturgeon and thriving poaching, a ban on uncontrolled fishing is regularly announced.

There are several varieties of black caviar:

Grainy - is the most popular and demanded. It is she who can be found in banks on store shelves. It has not only amazing taste, but also an appetizing appearance. Eggs are removed from the fish immediately after catching and driven through a special grate to get rid of the shell without breaking the integrity, then lightly sprinkle with salt. This allows you to save all the nutrients;
Ternary - produced quite rarely, in special cases. It differs from the previous variety in that the refined product is put in brine instead of sprinkling with salt, and after salting, it is placed on a sieve so that excess liquid is glass;
Salted - salted without removing the ovary (the film covering the eggs), then put into a small container and dried. After that, the shell is removed, and the caviar is pressed in special vats. This method is mainly used for processing stellate sturgeon caviar;
Yastichnaya - salted together with the film in its original form. It is the cheapest variety.

By the type of sturgeon fish, black caviar is:

Beluga is the most expensive and delicious. It has large eggs of a silvery or dark grayish color. After its use, a delicate nutty aftertaste remains;
Sturgeon - differs in eggs of a smaller size than in the previous species, and a slightly harsh taste with a hint of seaweed. This is due to its cost, which is slightly lower than that of the beluga;
Sevryuzhya is the most accessible, but also the smallest. It has a pleasant aroma and a rich black shade.

Selection and storage of black caviar

These simple tips will help you choose a quality product:

Do not buy a delicacy in the markets from unfamiliar sellers "off hand". Most likely it was mined, prepared and stored in improper conditions;
The product must necessarily have the appropriate certificates and accompanying documents;
It is better to choose products in glass containers. This will allow you to carefully examine the eggs. They must be homogeneous, without damage, with no liquid;
If you buy caviar in a tin can, inspect the container for damage and dents. You also need to shake the jar a little, and if the contents "dangle" inside or it seems that the container is filled with liquid, return it to the shelf - this is a low-quality product;
Perhaps the most important selection criterion is the price. 50 g of quality products will cost from 2,000 to 4,000 rubles, depending on the variety. Caviar is usually packaged in jars weighing 120-125 g. The cost of such a package is on average 5000-7000 rubles. A cheaper price tag indicates a fake.

You can store black caviar in a sealed package in the refrigerator for up to three months, and with an opened jar, you need to have time to consume the delicacy in five days.

The use of seafood in cooking

Earlier, when this delicacy did not have such a high price, it was served to the table in caviar dishes, and it was necessary to take it with silver spoons. Nowadays black caviar dishes are mainly pancakes and sandwiches with butter. You can also make cream cheese tartlets and garnish with eggs.

The delicacy goes well with:

Eggs;
Greens;
Cheese;
Almost any vegetables;
Citrus fruits.

The main thing is not to forget that a jar of seafood should be opened no earlier than 15 minutes before serving with a meal.

In conditions of artificial reproduction (aquaculture), caviar is represented by the following species: sterlet, beluga, bester, Russian, Siberian and white sturgeon. According to the method of preparation, it is divided into three groups: pressed, pasteurized and granular. By the type of packing - loose, packaged.

Useful properties of black caviar

Of the minerals in caviar, calcium, potassium, sodium, magnesium, phosphorus, as well as iron, manganese, iodine, silicon, and zinc are present in significant quantities. The fat of caviar is characterized by a higher iodine number than the fat of the meat of the same fish.

I must say right away that caviar is not a medicine. Therefore, we simply recommend it as a preventive and general tonic. The organic iodine, phosphorus and calcium contained in the caviar, as well as a large amount of very useful polyunsaturated fatty acids Omega-3 and Omega-6 in its proteins, help to improve brain activity, increase immunity, and reduce the likelihood of cardiovascular diseases, because reduce the risk of blood clots and improve blood circulation in small blood vessels.

Caviar cannot do without preservatives! This is true. Unlike other food stocks in cans, caviar does not undergo sterilization. Too tender, it turns into porridge when heated. The only way to preserve the caviar is to add preservatives and vacuum it. It is possible to make caviar without preservatives, but it will only be stored for 4 months, which means that from the spawning of fish until the New Year, it will not "last". The addition of a preservative allows the caviar to be stored for 12 months and to be purchased all year round. The preservatives in caviar are not a whim of producers, but a necessity caused by the characteristics of the product.

With all the fear and horror of consumers, you need to soberly assess the situation: the word "preservative" is not so scary as the specific substance that lies behind it. Common kitchen salt in caviar acts not only as a flavoring agent, but also as a preservative. You can also poison yourself with salt: a dose of 30-45 g causes acute poisoning. For preserving caviar, a mixture of two preservatives is used: sorbic acid E200 and urotropin E239. Both are approved for use, the presence of both in caviar in a certain amount is provided for in GOST 18173-2004 "Canned salmon caviar".
