Skates are an ancient group of fish that have been able to stay on the tree of evolution due to their unique biological properties. Ramps, like sharks, belong to the class of cartilaginous fish. Their entire skeleton is built from cartilage. Most of the fish from the fifteen families of stingrays live in salty sea water, but there are several freshwater species. Skat can be found in all seas and oceans, from the icy waters of the Arctic to warm tropical seas. They occur at any depth – from shallow water to 3 kilometers. Chutes feed on mollusks, echinoderms, fish, plankton. Culinary dishes from skates are present in the kitchen of many coastal peoples, from Portugal to Korea.

Ramps in culture and cooking

The first mention of a stingray in material culture is found in Egypt. The temple mural, written 3,500 years ago, depicts a multitude of marine fish, among which one can easily find a stingray. Ramps are mentioned in the culinary books of ancient Greece and Rome. Images of skates are found in ancient drawings covering religious vessels and structures in different countries of the world, from Europe and North Africa to Mexico and Tasmania.

Skates have tasty meat, in many countries they are considered a delicacy. They are eaten along the entire Atlantic coast of the United States. The European common slope is one of the important articles of the European fish market. In America, on the coast of the Pacific Ocean, they eat the California common stingray. In the French culinary encyclopedia „Larousse gaslronomigue“ mentioned filler from the stingray, ragout from the stingray and liver of the stingray.

Ramps of the Far Eastern Seas

The first description of the Far Eastern stingray in literature was made in 1814. In 1888, during an expedition aboard the Albatross, biologists described several new species of stingrays. However, until the end of the 20th century, this ancient species was studied very little. Skates were mined in very small quantities. There were no data on the number of skates in the Far Eastern region. At the same time, all over the world, especially in Asian countries, stingrays were mined in large quantities for human consumption as delicacies. In Japan, stingray liver has also been used to produce the anticancer drug Squalene.

The use of stingrays in medicine
In the XXI century, scientists have paid attention to popular recipes of oriental medicine, which mentioned stingray cartilage. It turned out that stingray cartilage, which was considered waste after processing stingray for food, is a valuable raw material that contains pure non-mineralized cartilage tissue. Studies have shown that cartilage extract reduces the rate of collagen cleavage, and also has anti-inflammatory activity.

Hydrolysates of cartilage of the slope can prevent diseases of the joints or significantly slow down the development of an existing pathological process.

Hydrolyzate is a specially treated component that converts the substances necessary for the body into an easily digestible form.

The slope cartilage hydrolysates are the substrate for the formation of a healthy extracellular cartilage matrix, which forms the basis of connective tissue. Hydrolysates maintain the normal composition and viscosity of the synovial fluid of the joint, contain vital macronutrients and trace elements.

Also, the skylar cartilage hydrolyzate has a high antiprotease activity, that is, an anti-inflammatory effect , which increases many times after enzymatic hydrolysis. Conventional culinary products from stingray are not effective enough to prevent the destruction of cartilage tissue.

Cartilage tissue consists of glucosamines, chondroitin sulfates, soluble collagen, hexosamines, non-collagen proteins.

The hydrolysates of stingray cartilages are also contained in the ARTROFISH complex developed by Far Eastern scientists . The complex contains low molecular weight inhibitors of metalloproteinases, free disaccharides and trace elements, free amino acids – substances that nourish cartilage tissue, contributing to its regeneration.

Natural chondroitin sulfate and glucosamine, contained in the complex ARTROFISH, have a high degree of digestibility, have a wide spectrum of therapeutic action and high safety index.

Benefits of Natural Chondroitin and Glucosamine

On the Russian market there are many products containing synthetic chondroitin and glucosamine. Such synthetic products are cheaper to manufacture than natural products, but are much worse absorbed by the human body and can cause allergic reactions.

Технологии выделения натуральных действующих веществ из хрящевой ткани ската и других гидробионтов гораздо сложнее и затратнее, но использование наукоемких процессов оправдано гораздо более высокой эффективностью. Также натуральные компоненты хорошо переносятся организмом и  лучше усваиваются.

The active ingredients derived from the cartilage of the slope   reduce pain and swelling in the affected joint and improve its mobility, reduce the dose of analgesics and nonsteroidal anti-inflammatory drugs (NSAIDs), slow the progression of degenerative processes in the joints, spine and paravertebral soft tissues, have a positive effect on metabolism cartilage tissue, stimulate the regeneration and reparative capabilities of chondrocytes, protect healthy joints from the development of the disease, do not cause side effects, serving t prevention of degenerative age-related changes, help athletes as a tonic with increased stress.
