Abstrakt: BSTRACT Mechanisms associated with the cleaning of food contact surfaces are not completely understood, and attempts to evaluate or improve cleaning processes are consequently hindered. The usefulness of ellipsometry as a technique to rate efficiency of different cleaning methods with respect to ability to remove milk soils from various materials is described. Film properties obtainable with ellipsometry, including a measure of the apparent mass remaining on a given surface after cleaning, can be used to provide an indication of the relative effectiveness of a cleaning method. This information contributes to establishment of criteria by which the effectiveness of a cleaning operation can be judged. [ABSTRACT FROM AUTHOR]
