PEF stands for Pulsed Electric Field. It is a non-thermal and non-chemical food processing technology that applies very short electrical pulses to biological materials.
In juice production, PEF treatment creates tiny, temporary openings in fruit cell membranes. This process, known as electroporation, allows juice and valuable intracellular compounds to be released more easily during pressing or separation.
Because PEF does not rely on heat, it helps preserve the natural characteristics of fresh fruit juice, including flavor, aroma, color, and nutrients.
Fruit juice is stored inside plant cells, protected by strong cell walls and membranes. Mechanical crushing and pressing break many of these structures—but not all of them.
This is particularly true for fibrous fruits such as pineapple, as well as apples, carrots, berries, and tropical fruits. As a result, a significant amount of juice often remains trapped in the pomace after pressing.
PEF helps overcome this limitation by increasing cell permeability before extraction.
PEF is typically applied after crushing or milling and before pressing or separation.
A simplified juice production flow looks like this:
Washing and sorting
Crushing or milling
PEF treatment
Pressing or separation
Clarification or stabilization
Filling and packaging
PEF allows producers to extract more juice from the same amount of fruit. Even small yield increases can have a major economic impact in high-volume juice production.
Because PEF is non-thermal, it helps preserve:
This is especially important for premium and not-from-concentrate juices.
PEF can reduce the need for intense mechanical pressing or long processing times, lowering energy use.
PEF can reduce the need for intense mechanical pressing or long processing times, lowering energy use.
Raw fruit quality varies by season and origin. PEF helps stabilize extraction performance despite changes in fruit ripeness or structure.
PEF improves process consistency by making fruit cell membranes more permeable before extraction, reducing the impact of natural variations in ripeness, variety, and origin. This results in more stable juice release, consistent yield and quality, and less need for frequent process adjustments despite changing raw material conditions.
PEF does not add or remove flavor compounds. Instead, it helps preserve what is naturally present in the fruit.
Juices produced with PEF often show:
Because oxidation and thermal stress are minimized, sensory quality is often improved compared to conventional extraction methods.
Shorter processing times and improved efficiency can reduce overall energy usage, contributing to more sustainable production.
No. While pineapple is a strong example (More on this below), PEF is widely applicable across the juice industry.
It has proven benefits for:
Any fruit or vegetable where juice is trapped inside cells can benefit from PEF.
PEF is a physical process that does not involve chemicals or additives. The electrical pulses are extremely short and do not remain in the product.
Yes. PEF systems are designed to integrate into existing juice production lines with minimal modification.
PEF systems are designed to work alongside existing equipment, not replace it. Traditional crushers, presses, and separators still perform the same mechanical functions. PEF simply improves the condition of the raw material before it reaches these steps.
PEF systems are available in different capacities and can be scaled for:
The technology can be adapted to different throughput requirements and product types.
Juice markets are becoming more competitive, with consumers demanding fresh taste, clean labels, and sustainable production.
PEF helps producers:
It offers a way to extract more value from the same fruit—without compromising quality.
Pineapple is a particularly good example of where PEF can deliver clear benefits.
Pineapple tissue is:
Traditional extraction often leaves juice trapped in the fiber-rich pomace. PEF helps open pineapple cells more effectively, increasing juice release and improving overall yield.
Producers often report:
PEF technology represents a shift toward smarter, gentler juice extraction.
By opening fruit cells at the microscopic level, PEF enables higher juice yield, better quality preservation, and more efficient processing. Pineapple juice is a clear example of where these benefits are especially visible—but the technology is relevant across the entire juice category.
For juice producers looking to improve efficiency, quality, and sustainability, PEF is a technology worth understanding.

Our team explored the impact of PEF treatments on coconut pulp to maximize milk yield. The goal? Extract more coconut milk with better consistency, higher oil content, while lowering the moisture in the pulp (less waste).
Traditionally, extracting juice from citrus peels involves high doses of enzymes and extended incubation times to break down the peel’s tough structure. However, PEF-assisted extraction offers a breakthrough in this process by reducing the need for enzymatic treatments and speeding up the entire process.
Ginger juice is increasingly in demand for its use in beverages, food products, and wellness supplements. By applying PEF, it’s possible to extract more juice.
