It is not that long ago that a large corporation recalled chocolate bars from its production. The reason for this – the somewhat unappetising idea of foreign particles in the product.
It can sometimes happen in the manufacturing process, for example, that metal or plastic parts come loose and get into the food product. Many manufacturers, therefore, try to find foreign particles before the product leaves the factory. For this, the products are X-rayed in their packaging. A software program then evaluates the visual images and detects unwanted objects automatically. In this way, food products that are not up to scratch can be filtered out during the production process.
