Food inspection

Seeing in the dark

X-ray inspection is a well-established tool for the detection of metal, glass and stone contaminants in food production. However, due to a reliance on detecting absorption contrast between the product and an impurity, the technique has little or no sensitivity to low density contaminants such as organic materials and plastics.

The additional materials information generated by the patented IBEX detector technology can detect plastic contaminants in chocolate bars down to 0.5 mm thickness and glass beads in glass jars of baby food down to 1 mm diameter. This is achieved despite a lack of clear absorption contrast in the image.
