Abstract
A method is for the extraction of a phytochemical, e.g., peptide or protein, or a chemical element from a macroalgae, by applying pulsed electric field (PEF)- or continuous electric field (CEF)-treatment to the macroalgae in a solvent, under pressure higher than the ambient pressure. A device and system carry out this method.
Claims13
A method for the extraction of a phytochemical from a macroalgae, said method comprising applying pulsed electric field (PEF) treatment to said macroalgae in a solvent, under pressure higher than the ambient pressure, thereby extracting said phytochemical from said macroalgae cells into said solvent,
- wherein the temperature of the solvent during treatment is maintained in the range of 25-90° C.,
- wherein the solvent comprises water and/or an alcohol,
- wherein the phytochemical comprises a protein, peptide, amino acid, phenolic compound, pigment, or a combination thereof, and
- wherein said PEF treatment is characterized by:
- (i) pulse number of from 1 to about 10,000;
- (ii) pulse duration of from about 50 ns to about 10 ms;
- (iii) electric field strength of from about 0.1 to about 100 kV/cm;
- and (iv) pulse frequency of from 0.1 to about 10000 Hz.
