process for the extraction of fatty acids from algal biomass

摘要

the invention relates to a process for the extraction of fatty acids from algal biomass comprising: the production of an aqueous suspension of the operation of algal biomass and subjecting the aqueous suspension of algal biomass hydrolysis and extraction with acid addition at least one organic solvent for non-polar, and at least one inorganic acid to the suspension aqueuse, algal biomass, in order to achieve the following three stages: (i) a semi-solid slurry with an algal biomass; (ii) an aqueous phase containing the hydrophilic inorganic compounds and organic compounds, and (iii) an organic phase containing the fatty acids. hydrophobic organic compounds other than the fatty acids.
