Application Areas » Contamination Detection


Physical contamination such as small glass fragments, bones, small stones, high-density plastic and rubberband, as well as packaging defects,
are frequently not detected by food producers.
Our X-ray inspection systems help reduce
the risk of spoilage and food poisoning.

Our LWX systems  can verify the integrity of seals in food wrappers, locate packaging defects and find foreign particles of (almost) any size in (almost) any kind of food.

High performance and fast image analysis software enables the automatic on-line detection and rejection of even the smallest and most difficult to detect foreign objects.

  • Optimal detection capability
  • Packaged or unpackaged products
  • Single or multiple lanes
  • Designed according to EHEDG guidelines
  • Low false reject
  • High probability of detection

Standard X-ray systems used for food inspection, especially for contaminants detection, are very much similar in terms of the fundamental technical basis for the acquisition of the X-ray images, 0.4 or 0.8 mm pixels, and Gadox (a robust, cheap and well-known material for X-ray imaging), to convert X-ray information to a digital number.

Our X-ray systems use low energy X-rays to produce high resolution, high contrast, highly detailed
X-ray images
of food products. The technology has received multiple awards, based on the very unique performance, with 50% higher contrast and typically 16 times better resolution.


The InnospeXion low energy X-ray technology finds the smallest bones, due to a much higher contrast between bones and meat and lower X-ray energy, due to a 16X better resolution, and an advanced software solution.

It offers the same speed as conventional systems, is hygienically designed, with a straightforward human interface.

High sensitivity and high resolution. Detection of sub-millimeter contaminants in large and thick cheese blocks cannot be accomplished using standard X-ray technology.

The InnospeXion solution offers: Detection down to 0.2 mm, Tailoring to the production line, EHEDG guidelines conformity, proven technology, dedicated software solutions e.g. for cheese internal structure quantification and validation.

Modern food production is a well controlled process. However, occasionally deviations occur, and contamination of the cheese with plastics, rubber, steel and other materials is possible.

Traditional X-ray imaging may find application to detect larger foreign objects of high density, but present day requirement is a detection of defects down to 0.2 mm and detection also of light foreign objects, such as some plastics and rubber, as well as integrity assessment of the packaging.

Glass splinters constitute a major problem in the production of food products packaged in glass jars, bottles, and containers. The splinters may have very hazardous consequences. X-ray technology has been used for years for the inspection of filled glass packaging with food products.

Our new X-ray technology pushes the detection level to the real need – to detect what is critical for the consumer. 


At InnospeXion, our fishbone detection methods and capabilities are constantly developed as a response to the increasing demands for bone-free products in the fishing industry.
