PEF for Algae Products

Product Examples: Algae oil, algae protein, carotenoids, chlorophyll.

Aim of PEF Treatment: Cell disintegration, cell proliferation, induction of stress reactions, microbial inactivation, enhanced extraction and refining efficiency.

Selective Harvesting

Algae are a significant source of nutraceuticals and valuable ingredients like pigments, vitamins, and proteins. PEF treatment of microalgae facilitates the harvesting and extraction of these valuable components. Algae products find applications in feed, food, and energy sectors. Pulsemaster’s process enables selective cell extraction of components such as lipids, promotes cell proliferation through PEF-induced stress reactions, and controls contaminants like protozoa in microalgae cultures.

Benefits of PEF

  • Enrichment with secondary metabolites due to PEF-induced stress on algae cells.
  • Targeted and controllable structural modification through cell membrane permeabilization.
  • Effective control of contaminants such as protozoa.
  • Enhanced product handling due to tissue softening.
  • Improved extraction and refining efficiency, leading to increased process capacity.
  • Retention of vitamins, minerals, pigments, antioxidants, flavors, and colors.
  • Energy savings.

More Information

Pulsemaster has developed industrial-scale equipment, named Conditioner, with treatment capacities up to 5,000 liters per hour (1320 US gallons per hour) for microbial inactivation and up to 50,000 kilograms per hour (110,000 pounds per hour) for cell disintegration.
