Containers with an End Flat Against the Side Wall or Bottom of a Retort: Effect on Heating Rate and the Sterilization
1Department of Food Science and Nutrition, 543 Shepherd Laboratories, University of Minnesota, 100 Union Street S.E., Minneapolis, Minnesota 55455.
Abstract:
In crateless retorts under certain conditions, it is possible for a few cans in the retort load to have an end flat against a solid wall. Cans under this condition will have a temperature response parameter, fh, larger than cans surrounded by the heating medium and a smaller sterilizing value (Fo). The fh and Fo-values of cans, both with an end flat against a solid wall and surrounded by the heating medium, are calculated to show the magnitude of the effect and the possible hazard when this condition exists and is ignored. It is recommended that the possibility of a wall effect be determined as part of the prevalidation inspection, and that the heat penetration test program be based on the results of this inspection.

Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
