Abstract
The article presents data on the commercial stocks and catch of the brown alga Saccharina japonica in the Tatar Strait of the West Sakhalin subzone and other coastal areas of the Far Eastern Seas. The chemical composition of S. japonica is shown depending on the collection period, processing methods, and drying. The technological yield of sodium alginate from S. japonica was 23-25%. The results of studies of the organoleptic and physical-chemical characteristics of sodium alginate, as well as the composition and ratios of the uronic acids in them, demonstrating their sorption activity, are presented. The currently recommended catch (RC) of S. japonica in the West Sakhalin subzone is shown to be 6 thousand tons, and 155.08 thousand tons for all subzones of the Far Eastern fishery basin, from which 171 tons and 3 thousand tons of high-quality alginate can be produced, respectively. Recommended to use S. japonica and other Laminariaceae seaweeds from the Far Eastern Seas as raw material in the production of sodium alginate for the food, medical, and cosmetic industries.
