Continuous pressurized extraction versus electric fields-assisted extraction of cyanobacterial pigments

Cyanobacteria pigments, in special carotenoids and phycobiliproteins, are usually used industry as raw extracts, although there is still no standard methodology for their extraction. For the co-extraction of phycobiliproteins from marine cyanobacterium Cyanobium sp., a continuous pressurized solvent extraction (CPSE) system an electric fields-assisted based ohmic heating were optimized using Central Composite Designs, with three factors each: time (t), temperature (T) and, flow (f) CPSE; time, frequency (F) heating. The content pigments antioxidant capacity extracts evaluated. All tested seem to influence different ways: high (70 °C) had positive impact on rate both methods, while depended principle. Flow affected directly efficiency these methods indeed suitable cyanobacterial extraction, achieving good results. Optimal conditions CPSE T = 70 °C, t 20 min f 1.5 mL min?1, they 5 F kHz. Both, systems allowed obtaining better yields when compared previously method (homogenization), here reference. However, was best sp.
