Complex technology of production of extractive biologically active substances from brown algae of White Sea
During complex processing of seaweeds arise conditions for full extraction of valuable products from them, reduces quantity of wastes. In this relation is actual complex processing of brown algae species <i>Laminaria</i> (<i>Laminariaceae</i>), growing in White Sea, with aim to receive at the same time mannitol, sulphated polyose, neutral polyose and sodium alginate. Have been compared three methods of complex processing of seaweeds with usage of spirit, water extraction as well as processing of seaweeds according to scheme that includes spirit as well as water extraction. In the result of these researches it proved that the most rational way is to process seaweeds by integrated scheme allowing receiving final products of larger assortment without losses in quality.
