Chemical composition of brown algae from the Black Sea: genus Cystoseira, perspectives for their use

Abstract

Data are presented on the safety and quality of brown seaweeds (Cystoseira crinita and C. barbata) which were collected in different Russian coastal areas of the Black Sea (settlement Dzhubga, Sudak Bay, settlement Shepsi, Blue Bay). The results of investigations have shown that the seaweeds collected in the areas under study comply with the safety requirements of SanPin 2.3.2.1078-01 by neither total infestation nor by lead and mercury concentration. It is a proof of unfavorable ecological conditions of these areas and when these seaweeds are used it will be necessary to carry out their pre-handling aimed at their detoxification. Conditions for preprocessing of this raw material have been worked out. These seaweeds are proved to be a promising raw material item for complex processing and obtaining biologically active components and biological fuels. A promising technological scheme of complex processing of Cystoseira from the Black Sea has been elaborated.
