Influence of Geographical Location of Spirulina (Arthrospira platensis) on the Recovery of Bioactive Compounds Assisted by Pulsed Electric Fields

Spirulina (Arthrospira platensis) has been consumed by humans since ancient times. It is rich in high added-value compounds such as chlorophylls, carotenoids and polyphenols. Pulsed electric fields (PEF) an innovative non-thermal technique that improves the extraction of bioactive from diverse sources. PEF pre-treatment (3 kV/cm, 100 kJ/kg) combined with supplementary binary solvents at different times was evaluated to obtain optimal conditions for extraction. In addition, results obtained were compared conventional treatment (without constant shaking) strains geographical locations. The recovering after applying mixture EtOH/H2O 180 min. recovery total phenolic content (TPC) (19.76 ± 0.50 mg/g DM (dry matter) (0.50 0.01 DM) more efficient Spain. On other hand, there a higher chlorophylls China. highest antioxidant Costa Rica. These show PEF, condition growing affect Spirulina. combination promising technology due its environmental sustainability.
