The F0-value is a fundamental metric in thermal process validation for food, pharmaceutical, and biotechnology industries. It quantifies the lethality of a sterilization cycle by expressing the equivalent exposure time at a reference temperature of 121.1°C, typically using a z-value of 10°C for Geobacillus stearothermophilus spores. This isothermal calculation provides a standardized baseline for comparing different thermal cycles when the process temperature remains constant.
