Evaluating a Ground-Beef Patty Cooking Process Using the General Method of Process Calculation
1Department of Food Science and Nutrition, University of Minnesota, 585 Shepherd Labs, 100 Union Street SE, Minneapolis, Minnesota 55455, USA.
Abstract:
The General Method of process evaluation is used to calculate F160.0°F values for two ground-beef patty frying tests. The F160.0°F value is then used to compare the adequacy of the two frying processes to control pathogenic microorganisms. The several elements of process design and evaluation are described: (1) designing the microbial control process, (2) performing the General Method of process calculation including construction of the relative kill time graph, (3) selecting the z value, (4) evaluating relative kill time, lethal rates, and FT values, and (5) calculating F160.0°F values for two ground-beef patty frying tests as examples.
