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.
Claims27
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 said PEF treatment is characterized by at least one of:
- (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.

A device for the extraction of a phytochemical from a macroalgae, said device comprising:
- (i) a pulsed electric field (PEF) treatment chamber comprising at least one inlet and at least one outlet;
- (ii) a first electrode and a second electrode positioned for creating an electric field in said treatment chamber;
- (iii) optionally a pressure generating mean for generating pressure within said treatment chamber;
- (iv) optionally, an agitator and/or air bubbling unit for agitating and mixing the content of said treatment chamber;
- and
- (v) optionally, a filtering unit located at the outlet,
- wherein upon introducing said macroalgae in a solvent into said treatment chamber, and applying PEF treatment characterized by at least one of:
- (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 to said solvent, under pressure higher than the ambient pressure, said phytochemical is extracted from said macroalgae into said solvent.
