Enhance shelf life, preserve taste, colour, aroma, and nutritional value, and optimize extraction for your juices and smoothies.

PEF offers a strong alternative to both thermal and HPP processing, delivering reliable, low-temperature, continuous 24-hour operation for cost-efficient inactivation of fruit and vegetable juices and smoothies. It also enhances extraction, resulting in higher juice yields and better overall efficiency.

PEF benefits for juice and smoothies

  • Assorted colorful juice bottles lined up on a table.

    Produce premium quality juice with extended shelf-life

    PEF allows for the safe inactivation of the raw product at low temperatures, preserving more freshness and nutritional value compared to traditional pasteurisation methods.

  • Industrial machine in a factory setting with the Elea logo, featuring control panel and warning signs, surrounded by metallic equipment and piping.

    Easy installation, continuous processing and scalable to your requirements

    Our scalable PEF Advantage Pipe systems (1, 10, 100, 1000) handle 50L–5,000L per hour. With a compact, low-maintenance design, they’re easy to install and configure. As a continuous process, PEF offers a compelling alternative to HPP.

  • Low running and maintenance costs

    Low running and maintenance costs

    PEF processing costs just 0.01–0.02 € per litre, making it the most cost-effective low-thermal technology for juices and smoothies.

  • Row of clear bottles filled with orange juice on a production line in a factory setting.

    Use any packaging material

    PEF is applied before filling and works with any packaging type, including PET, glass bottles, pouches, and other consumer containers. It also supports B2B solutions like sterile tanks.

    PEF dramatically improves extraction

    PEF causes pores to form in the plant cell which improves extraction. Yield can be increased and valuable compounds can be extracted without the need for additional enzymes.

Inactivation Benefits of PEF for Juice & Smoothies

Three bottles labeled "PEF Treated" in red, green, and orange, promoting fresher taste, better color, and longer shelf life.

Process time vs quality

PEF technology reduces energy consumption while ensuring a longer shelf life and superior product quality. By preserving valuable compounds, it helps juices and smoothies maintain their natural nutritional content — including vitamins, antioxidants, and pigments — resulting in a healthier, fresher, more visually appealing, and longer-lasting product

Comparing PEF to thermal and HPP

PEF’s low-temperature processing delivers a product quality on par with HPP, but with greater cost-efficiency and enhanced production advantages

  • PEF’s low-temperature processing delivers superior product quality compared to traditional thermal methods and matches the high standards of HPP.

  • PEF inactivates harmful microorganisms with electroporation.

    HOW PEF WORKS FOR INACTIVATION

  • Like thermal methods, PEF is a continuous process capable of 24-hour production — unlike HPP, which operates in batches

  • PEF has much lower energy requirements than thermal and HPP.
    Thermal: 150 kJ/kg
    HPP: 280 kJ/kg
    PEF: 110 kJ/kg

  • PEF can use any type of packaging.
    Thermal: Ultraclean/hotfill
    PEF: Ultraclean
    HPP: Standard

  • PEF runs automatically, with no need for an operator — unlike HPP.
