1. Contamination under thermodynamic control: effect of the partition coefficient
1.1 Definitions
1.1.1 Microscopic description of thermodynamic equilibrium
Noting the packaging, P, and the food, F, thermodynamic equilibrium corresponds to a situation where the cumulative free energy of P and F, noted GP+F, is minimal, and characterizes the state towards which the packaging-food system spontaneously evolves when P and F are placed in contact. It corresponds to thermal, mechanical and chemical equilibrium between the two compartments. At uniform pressure and temperature between P and F, the state...
