Why in the Far East to increase the production of kelp?
At the beginning of 2018, production of biologically active additive from kelp will start on Sakhalin. In November, the regional government allocated a subsidy of 6,5 million rubles for this project. As head of the Sakhalin Agency for Investment Promotion (SakhAPI) Anton Sheredekin told EastRussia, the company is now working in a test mode.
In SahAPI they say that there are no analogues to this project in Russia. It is based on innovative domestic technology, in which strong acids, ethyl alcohol and mineral salts are not used to produce useful substances from kelp.
According to the deputy head of the Sakhalin Oblast Fisheries Agency, Sergei Oma, this year the kelp fishery in the region was conducted by 24 enterprises.
- Some of them are mined in frozen form for further processing on the mainland, part - boiled, dried and the resulting semi-finished product is delivered to the market. In addition, several Sakhalin plants make canned seafood. This year, 10 thousand tons were produced for 6,5 months, and 2016 thousand tons in 4,7. Such fluctuations in production volumes are related to demand in the domestic market. It is problematic to supply Sakhalin laminaria to foreign markets. For example, Japan has fixed quotas for imports of this product - no more than 200 tons per year, "says Sergey Om.
Another region in which seadores are traditionally engaged is Primorsky Krai. There it is mined by six enterprises, which by the middle of November collected 1021 a ton. Another 10 enterprises for 9 months 2017 year have grown 1199 tons of kelp, and realized - 309 tons. In comparison with the same period of 2016, these indicators were 1104 and 533 tons, respectively. The press service of the regional government reported that the entire volume of extracted kelp is supplied to the domestic market.
Analysis of electronic wholesale sites offering sea kale for sale shows that manufacturers from China actively compete with the domestic manufacturer in the domestic market. Obviously, Russian companies have something to fight for.
A traditional product made from sea kale is a salad, but Far Eastern scientists are trying to find other uses for it. So, in March of 2017, technologists from the Far Eastern Federal University (FEFU) presented kelp, enriched with selenium, in November they introduced marmalade based on broth of sea kale. However, this is not the only sweetness with algae. As the EastRussia professor of the Department of Food Science and Technology of the School of Biomedicine FEFU Oksana Tabakaeva told, the nanoparticles of kelp are added to chocolate. In addition, sea kale may well replace the usual gelatin.
"A product using gelatin at 35 degrees Celsius loses its stability, and when using laminaria derivatives it retains its shape even at a temperature of 60 degrees," Tabakaeva said.
Oksana Tabakaeva says that the development of adding sea kale to mayonnaise, sausages and cooked sausages has been successfully carried out.
- Extracts from kelp are introduced into the water phase of mayonnaise, enriching it, thus, with biologically active substances. In addition, the graduate student of our School has developed sausages and sausage with kelp. In September, the tasting of this product was organized in Harbin University. As a result, she received a diploma for innovative development, - the professor said.
Responding to a question from EastRussia about the prospects for implementing the results obtained in the industry, the professor noted that manufacturers are not just interested in releasing new products - inertness is too great, but there is some progress in this process.
- One of the confectionery enterprises of Primorye is already producing chocolate with laminaria, and the development associated with sausages will surely find its application. I think that in the next two to three years we will see products made using our developments in stores. Laminaria is an algae that is well studied and is already actively used not only in the food industry, but also in the pharmacological and cosmetic industries, ”concluded Tabakaeva.
