The Heat Penetration Factor (f_h) is a fundamental parameter in thermal process engineering used to characterize the rate of heat transfer to the slowest heating point of a food container. It represents the time required for the temperature difference between the heating medium and the product center to decrease by 90% during the linear heating phase. Accurate determination of f_h is essential for validating thermal sterilization processes and ensuring food safety.
