PEF for Production of Protein Concentrates

Product Examples: Potato protein concentrates, egg white ovoalbumin, porcine blood plasma, protein-rich products.
Aim of PEF treatment: Cell disintegration, microbial inactivation, protein structure modification, enhancement of extraction.

The Power of Protein

Our diet consists of three macronutrients: protein, carbohydrate, and lipid, along with numerous micronutrients (vitamins, minerals, antioxidants, etc.). The use of both plant and animal-based proteins, which contribute to the maintenance of skeletal muscle mass, is on the rise. Proteins enhance the nutritive value and textural quality of foods. Results so far indicate that PEF can be applied to foods and beverages at intensities high enough to reduce microbial load without damaging protein structure and functional properties, such as foaming and gelling.

PEF Treatment of Ovoalbumin Solutions

Ovoalbumin, the primary protein in egg white, is crucial for the gelling properties of eggs and egg products. Decontaminating liquid ovoalbumin solutions with combined PEF treatment and low-temperature storage does not induce permanent modifications in ovoalbumin. Unlike thermal treatment, no changes are detectable in the UV spectra of native and PEF-treated ovoalbumin.

Decontamination of Porcine Blood Plasma

PEF treatment can decontaminate protein-rich products without affecting protein functionality. A potential application is the decontamination of porcine blood plasma to reduce the microbial load in plasma powder.

Controlled Protein Modification

In addition to decontamination without affecting proteins, PEF technology can be applied for targeted and controlled protein modification. Interest in this application is growing. We welcome inquiries from commercial companies and research institutes interested in exploring specific applications of PEF technology for affecting protein structure.

Benefits of PEF

  • Mild preservation without affecting protein functionality.
  • Improved extraction and refining processes with reduced energy consumption.
  • Increased process capacity.
  • Targeted and controlled modification of protein is achievable.
  • Continuous process and rapid technique.
  • Compact equipment footprint and quick process startup.
  • Low energy requirements.
