In the 70s of the XIX century in the Gulf of Peter the Great, off the shores of the Far East, Kamchatka crabs were already caught. The first Russian crab cannery in Primorye began operating in 1908. After 1914, a big break came, in Russia there was no time for the production of delicacies. Only in 1923, Soviet canned crab appeared on the international market, and by the end of 1928, Russian crabheads began to win primacy on the world market of crab, which they still retain today.

Canned crabs were exported, and the Soviet people were not accustomed to this delicacy. Therefore, when crab canned goods appeared in the stores, they were little bought. In 1938, an advertising poster, which later became famous, “It’s time for everyone to try how crabs are tasty and tender” even appeared.
Crab or cancer
In fact, the body structure of the Kamchatka crab is not a crab at all, it belongs to crustaceans. But outwardly he looks like a crab, and that is the name fixed. There are many interesting things in the anatomy of the Kamchatka crab: for example, the stomach is closer to the head and the heart is in the back of the body. The crab has 10 legs, he goes to eight, and the remaining two serve as his “hands”, he cleans the gills with his right hand, gut it with a right “hand” to eat sea urchins, and his left, like a knife, cuts worms and other soft food.
Kamchatka crabs live for 15–20 years, and winter each year off the western shores of Kamchatka, plunging to a depth of 200 meters, spring up to bask in shallow water. Each year, crabs molt, and in 3 days of molting, not only their shells change, but the entire gastrointestinal tract and tendons are renewed.
Russian chitin society
In the production of meat from crab, the shell contains up to 35% chitin, up to 30% protein, minerals and lipids.
Chitin was discovered in 1811, and the natural polysaccharide chitosan, a derivative of chitin, was first obtained from chitin only in 1859. The first works in Russia related to the modification of chitin were carried out under the guidance of academician P. P. Shorygin.
Attempts at the practical use of chitosan were undertaken in 1941 by F. I. Sadov for dyeing and processing fabrics. After the war, in the 50s of the XX century, extensive research began on chitin and chitosan. In the 1970s, the first batches of chitosan were produced at the Moscow Chemical Chemicals Plant. Voykova.
At the same time, it was proved that the treatment with chitosan solutions of various technical papers significantly improves their characteristics; self-absorbable surgical sutures were created on the basis of chitosan.
Since 1961, chitin research began in Moscow at the Institute of Biophysics of the USSR Ministry of Health. The main task of these studies is relevant today – the creation of anti-radiation drugs. In animals, the high efficacy of the obtained preparation in the fight against radiation was proved, but for a long time these works were classified as secret only in recent years.
In the mid 80s of the last century, pilot plants were created to produce chitin and chitosan in Vladivostok and Murmansk, then industrial production of chitosan began in Moscow, the Moscow Region and in the Primorsky Territory, in the cities of Partizansk and Dalnegorsk.
In 1999, it was decided to establish the Russian Chitin Society to coordinate all research in the field of chitin and chitosan in Russia.
In October of this year, the 13th International Conference „Modern Perspectives on Chitin and Chitosan“ and the 7th Congress of the Russian Chitin Society in Ufa will be held .

Chitin and chitosan
Chitin is a polysaccharide similar in structure to cellulose, it is an integral part of the skeleton of many animal species, mainly crustaceans, insects, and is found even in fungi. Crab shell is the main raw material for chitin. The crabs of different ages change the chitin content in the shell: immediately after shedding, in the new soft shell only 2–5%, in the “old” shell it is already 18–30%. Chitin is also found in other crab organs, in particular, in the gills of chitin 70%.
Chitosan is currently used in the food industry, in the manufacture of lacquers for furniture, in medicine for the manufacture of medicines, soluble films and surgical sutures, medical contact lenses, for the treatment of burns and bedsores.
Chitosan is able to actively adsorb molecules of organic and inorganic nature, is effective for increased toxic load, food poisoning and various intoxications. Chitosan attracts fat molecules and removes them from the body. One molecule of chitosan removes from the body fat 10-12 times its molecular weight, so it is used in diet therapy to reduce body weight.
o with gastritis and ulcers, it clears the gastrointestinal tract from pathogenic bacteria, reduces inflammation, promotes healing of ulcers, stimulates the regeneration processes of the mucous membrane of the digestive tract;
o contributes to the rapid and complete release of the body from toxins , pathogens, fungi, allergens, salts of heavy metals, radionuclides;
o getting into the stomach, swells, turning into a gel-like substance, protecting the gastric mucosa from erosive processes;
o reduces the level of cholesterol, triglycerides and total lipids in the blood serum;
o stimulates the formation of bifidobacteria and beneficial intestinal flora.
