N2 - Conventional X-ray transmission radiography has long been used for online detection of foreign bodies in food products relying on the absorption contrast between the foreign body and food product. In this paper, we present a novel approach for detection of organic foreign bodies such as paper and insects in two food products using X-ray dark-field imaging with a grating interferometer. The ability to detect the foreign bodies is quantified using a measure of the contrast-to-noise ratio.
