Abstract
A method and apparatus for analyzing one or more elements of targeted moving food surfaces uses laser-induced breakdown spectroscopy to detect the presence, absence, or amount of an element on a heterogeneous surface of an object, including surfaces of food products. A laser is used to quantify an element concentration without destroying the object. The method can be configured to include an automated on-line system comprising a closed-loop feedback control system operable to select a predetermined concentration.
