Revolutionizing Snack Manufacturing with PEF Technology for Dehydrated Fruits and Vegetables

  • PEF

Pulsemaster introduces its advanced Pulsed Electric Field (PEF) systems, revolutionizing the manufacturing of dehydrated healthy snacks. This technology is ideal for food and snack processors eager to introduce innovative premium snack products made from potatoes, vegetables, and fruits. Pulsemaster’s PEF technology employs a wet disruption method on plant cells before extraction and drying, offering a healthier snack alternative.

A PEF Pre-Treatment for Superior Dehydration

Utilizing PEF as a pre-treatment alters the plant cells of raw materials, enhancing the dehydration and drying processes. Pulsemaster’s PEF allows for high-speed, low-temperature drying, either above or below the freezing point. This preserves the nutritional value, bioactivity, flavor, color, and texture better than traditional methods, offering an improved alternative to classical dehydration techniques.

Elevating Drying Processes and Quality

PEF is the preferred pre-treatment for classical air-dried, osmotic dried, freeze-dried, and vacuum-dried fruit and vegetable products. As a physical, non-thermal, and low-energy processing method, Pulsemaster’s PEF complements dehydration by forming pores in cell membranes. This cell disruption, controlled by electric field intensity and pulse number, enhances extraction and drying, leading to:

  • Faster drying processes with improved quality, rivaling fresh products
  • Enhanced color, aroma, and authentic flavors
  • High nutritional retention
  • Better water release, preserving texture and shape
  • Crisp, fresh-tasting dehydrated fruits and vegetables
  • Increased yield and production capacity
  • Reduced energy consumption
  • Optimizing Frozen Vegetables with High Water Content
  • For the production of frozen vegetables like peppers, onions, garlic, and mushrooms

Pulsemaster’s PEF technology serves as an effective wet disruption method. This process extracts free water before freezing, preserving cellular structure and organoleptic qualities, ensuring authentic flavors.

Experience the Difference with Product Trials

Pulsemaster invites you to compare the results of your current process with our PEF pre-treated dehydration, drying, and freezing processes for fruits, vegetables, and other heat-sensitive products.

Collaborating with Industry Leaders

Pulsemaster collaborates with renowned partners for testing and development:

Agriculture et Agri-Food Canada Saint-Hyacinthe Research and Development Centre

Cintech Agroalimentaire

Cintech, specializing in various dehydration and freezing technologies, combines Pulsemaster’s PEF pre-treatment with methods like EnWave dehydration technology for enhanced product quality.

Pulsemaster and Cintech conduct product trials for dehydrated fruit and vegetable snacks using both Pulsemaster PEF and EnWave Radiant Energy Vacuum (REV) dehydration technology. This innovative REV process offers a faster, cost-effective alternative to traditional freeze-drying or air-drying methods.
