How do food processors detect metal or glass fragments in frozen meals?

Food processors ensure the safety of frozen meals by using specialized inspection machines designed to identify and remove foreign contaminants. After the components of a meal are assembled into trays, these automated systems scan the product to detect the presence of undesirable items, such as metal or glass fragments, before the trays are conveyed to the freezer.1

This inspection step is a critical component of the assembly and freezing process, ensuring that only products meeting safety standards proceed through the production line.1
