PEF for Dietary Fiber Extraction

Product Examples: Inulin, oligosaccharides, chicory root, onions.
Aim of PEF Treatment: Cell disintegration, enhancement of extraction processes.

Oligosaccharides and Inulin

Many people do not consume the recommended amounts of daily fiber. Dietary fibers like oligosaccharides and inulin are carbohydrates found in various plants. Chicory root, a major commercial source of inulin, along with onions, leeks, garlic, legumes, wheat, asparagus, and other plant foods, are rich in oligosaccharides and inulin.

Selective Extraction

Chicory is an excellent source of inulin, a fructose polymer with significant nutritional and health benefits. Traditional inulin extraction methods are costly and necessitate processing the entire crop within 45 to 60 days. Extracting inulin from dried chicory can extend the processing season and reduce costs. Pulsemaster’s process enables selective extraction of cell components through PEF processing. By permeabilizing cell membranes, PEF facilitates tissue softening and enhanced mass transport, leading to improved inulin extraction from chicory root, higher product quality, and increased process capacity.

Benefits of PEF

  • Targeted and controlled structural modification through cell membrane permeabilization.
  • Enhanced handling due to tissue softening.
  • Reduced cutting force required.
  • Improved extraction and refining processes.
  • Increased process capacity.
  • For inulin production, PEF results in greater extraction and refining yields, enhanced inulin juice purity, and higher process efficiency with significant reductions in energy, labor, and operational costs.
  • Continuous process and rapid technique.
  • Compact equipment footprint and quick process startup.
  • Low energy requirements.

More Information

Pulsemaster has developed a range of industrial-scale equipment, named Conditioner, with treatment capacities from 1,000 kg/h to 50,000 kg/h (110,000 lb/h) for cell disintegration. On a commercial scale, total costs are expected to be around 1 Euro/ton (0.1 Eurocent per kg / 0.056 US Dollarcent per lb). There are practically no size limitations.
