White Asparagus Dehydration Transformed with PEF Technology
With Pulsed Electric Field (PEF) technology, producers can achieve faster drying, lower costs, and superior product quality of white asparagus.

Manufacturing Dehydrated potato products—such as flakes and powders—comes with its own set of complexities. Traditional methods struggle with inefficiency, inconsistent drying, and loss of quality.
OptiCept’s CEPT® technology, based on Pulsed Electric Field, offers a solution with lab-proven results demonstrating major improvements.
In this post, we’ll take a closer look at how PEF reduced the drying time of potato products.
Potato dehydration processors face a range of challenges tied to efficiency, quality, and cost.
One of the biggest issues is the energy-intensive blanching step, which adds high operational cost while risking over-softening or leaching nutrients and color.
Processors also struggle with long drying times, limiting throughput and increasing energy consumption, especially as demand for potato flakes and powders grows.
Maintaining consistent product quality—uniform color, texture, and rehydration performance—can be difficult, particularly when raw material variability is high.
Additionally, issues include equipment bottlenecks, high maintenance needs, yield losses due to thermal damage, and the challenge of improving sustainability metrics without compromising performance.
Together, these factors make production expensive, energy-heavy, and difficult to scale efficiently.
PEF works by creating microscopic pores in the cell membranes through short, high-voltage pulses—a process known as electroporation. It’s a non-thermal method that enhances water release during drying, enabling:
This method, of course, not only applies when dehydrating potatoes. PEF can be applied in a wide range of dehydration processes, including onions, carrots, asparagus, pineapple, mango, and more.
The trial using the Folva variety showed that applying PEF in potato dehydration led to:
By using the OPTICEPT® SD7 PEF system, producers of dehydrated potato products can expect:
OPTICEPT® SD7 is the next-generation PEF system. Specifically engineered for optimizing the dehydration of fruits and vegetables. The OPTICEPT® SD7 PEF system is installed and retrofitted into existing production lines right after the preprocessing (sorting, washing) and before steam washing, cutting, and drying. The system has a very small footprint and fits into most processing lines.
As mentioned, the method can be applied in a wide range of commodities, from pineapple and mango to carrots and cranberries.
