Extraction of valuable compounds from Arthrospira platensis using pulsed electric field treatment
Abstract (englisch):
Pulsed electric field (PEF) treatment was evaluated for phycocyanin and proteins
extraction from Arthrospira platensis (Spirulina platensis). PEF extractions were
performed using different specific energies (28, 56 and 122 J·ml-1 of suspension) and
the results were compared to the extraction with bead milling. At highest PEF-treatment
energies a damage of the cell morphology could be observed and the highest yields (up
to 301.3 ± 16 mg g-1 and 48.4 ± 4.4 g g-1 of phycocyanins and proteins, respectively)
could be obtained at 122 and 56 J·ml-1. The yields increased with incubation time after
PEF-treatment. The antioxidant capacity of the extracts obtained after PEF-treatment
was higher than of those obtained after bead milling. PEF treatment is a promising
technology to obtain blue-green antioxidant extracts from A. platensis in an
environmental friendly process.
