PEF treatment of fish

Product examples: Fresh fish fillets, fresh fish, dried fish, salted fish, marinated fish
Aim PEF treatment: Cell disintegration and improved mass transport processes, inactivation of parasites such as nematods

Enhanced drying, brining and marinating

Important fish products – besides fresh and frozen fish – are dried, brined or marinated fish. Mass transport processes, such as moisture transport and removal, are improved by the electroporation of fish tissue, resulting in enhanced drying, brining and marinating of fish. The required field strength for cell desintegration of fish is 1,0 – 3,0 kV/cm and the energy delivery is 3 – 10 kJ/kg.

Benefits PEF

  • Enhanced drying, brining and marinating processes
  • Improved micro-diffusion of brine and marinade in the fish tissue
  • Improved waterbinding due to the interaction between protein, salt and phosphate
  • Inactivation of parasites in fish fillets
  • Reduced labor costs

More information

Pulsemaster’s range of industrial scale equipment – named Conditioner – for cell disintegration of fresh fish and inactivation of parasites such as nematods in fresh fish fillets, allows processing capacities of 1 to 5 tons per hour per system.
