METHOD OF PROCESSING BROWN ALGAE Russian patent published in 2010 - IPC A23L1/00 

FIELD: chemistry.

SUBSTANCE: invention relates to the technology of processing brown algae. Algae is sluiced with 96% ethanol and held at room temperature for 5-7 minutes to obtain an extract I. Further, the algae are thrice extracted with 96% ethanol for 10-15 minutes at room temperature to obtain extracts II-IV. Each of the extracts I-IV is concentrated to a small volume. Hexane solvent and water are twice added to each concentrate and the mixture is left to separate the water-alcohol and hexane phases. Hexane phases are combined and concentrated to obtain chlorophylls. The water-alcohol phases are combined and chloroform and water are added. The mixture is stirred and left for separation into two phases. Further, the lower chloroform phase is separated and washed twice with water and concentrated to obtain fucoxanthin. Residue of algae I is infused into a mixture of solvents acetone-alcohol in ratio of 1:1 for a day. The extract is concentrated, dissolved in chloroform and washed twice with water to obtain an extract of glyceroglycolipids of algae II residue. The algae II residue is dried and used to obtain salts of alginic acids.

EFFECT: invention enables to obtain highly pure different biologically active substances from one raw material: fucoxanthin, chlorophylls, glyceroglycolipids, salts of alginic acids with high output.
