PEF for the Production of Seaweed Extracts

Product Examples: Kelp extracts, kelp oil, kelp protein, carotenoids, chlorophyll.

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

Diverse Group of Macroalgae

Seaweeds are a diverse group of large marine macroalgae. They are utilized for human consumption, as a protein source in fish feed, in pharmaceuticals, phycocolloids, other biochemicals, and as a carbon source for biofuel production. Aquaculture production of seaweeds is primarily dominated by kelps. Valuable seaweed extracts include agar, carrageenan, and alginate, which are used in food, nutritional supplements, and fertilizers.

Harvesting and Extracting Valuable Ingredients

Pulsemaster’s process enables selective harvesting and extraction of valuable components such as lipids from seaweeds. It also facilitates cell proliferation through PEF-induced stress reactions. Additionally, PEF treatment can control contaminants like protozoa in kelp cultures, thereby protecting the microscopic stages of kelp and other seaweeds.

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.
