Abstract
A method and apparatus for analyzing one or more elements of targeted moving snack food surfaces uses laser-induced breakdown spectroscopy to detect the presence, absence, or amount of an element on a heterogeneous surface, including seasoned and ready-to-eat snack foods. A laser is used to quantify the element concentration without destroying the targeted sample. An automated on-line system may be integrated into the method to create a closed-loop feedback control system, adjusting the concentration as desired.
