The safety of food is taken for granted by consumers. The preservation of food via the process of pasteurization in autoclave pots, full-water immersion or shower type autoclaves or retorts is essential for this.
Inactivation of pathogenic germs to increase food shelf-life with complete preservation of nutrients via a core temperature of between 60 °C and 100 °C
Systems should be validated once a year
Warming Phase:
The water temperature is raised in a pot autoclave to the pre-defined pasteurization temperature, for example, +95 °C.
Pasteurization:
The pasteurization temperature is achieved throughout the entire system, ensuring a homogeneous temperature distribution. The process duration and pasteurization temperature vary depending on the product.
Cooling Phase:
The product is removed from the pot autoclave and brought to room temperature. Depending on the product and system type, a Clean-in-Place (CIP) cleaning may be necessary to prevent the formation of microorganisms in the system.
Checking and regular verification as to whether the pasteurization process is effective
Determination of the correct hold times/pasteurization temperatures and the P-value
Measurement of temperatures at the coldest point in the process
Correct placement of the data logger is crucial for ensuring the reliable killing of germs in the product
