|
In order to prediction of lethal effects on target microorganisms, this study was developed the program in the basis of Excel that was systemized with Visual Basic. This program was automatically calculated the lethal effects (L and Fo value) by using thermal characteristics (D and z value), kinetic model and mathematic model. For the selection of target microorganisms, we are selected two microorganisms because of spoilage increasing by acid production and decreasing quality of food, and heat resistance microorganisms. The target microorganisms were Bacillus cereus (D_{121.1}=0.0065 min, z=7.8^{circ}C) and Bacillus subtilis (D_{121.1}=0.5 min, z =12^{circ}C). The program was developed for the target microorganisms, and that was very useful for various microorganisms that direct introducing known D and z value.
