A method and an apparatus for identifying foreign bodies in packaged beverages are employed where the package and the beverage are translucent and the foreign bodies have a density greater than that of the beverage. A novel aspect of the method is that the package is oriented in a first position in which the foreign bodies are collected on an internal, upwardly directed face in the package, and the package is then turned to at least one subsequent inclined position having an inclination sufficient for the foreign bodies to perform a downward movement along said face. During this movement, at least one of the foreign bodies is identified by comparing at least two successive position-determining detections. This provides a method and an apparatus for certain identification of foreign bodies in dark as well as light beverages, and in disposable as well as recyclable packages.
