Tyndallization vs. Pasteurization: What's the Difference?

Edited by Sumera Saeed || By Sara Rehman || Published on February 3, 2024
Tyndallization involves repeated heating and cooling to sterilize, especially for heat-resistant spores, while pasteurization uses moderate heat to reduce microbes in food, preserving taste and quality.

Key Differences

Tyndallization is a sterilization process involving heating substances at 100°C, cooling them, and then reheating. This process targets heat-resistant bacterial spores. Pasteurization, in contrast, involves heating liquids like milk to a specific temperature below boiling to kill pathogens without altering the product's quality.

In tyndallization, the cycle of heating, cooling, and reheating is critical to destroy spores that germinate between cycles. Pasteurization employs a single, continuous heat treatment, sufficient to reduce harmful microorganisms while maintaining the nutritional and sensory properties of the liquid.

The main objective of tyndallization is to achieve a high level of sterilization in substances where autoclaving is not feasible. Pasteurization, however, aims to make food products safe for consumption and extend their shelf life without the need for refrigeration.

Tyndallization typically requires specialized equipment and more time due to its repetitive process. Pasteurization is a simpler, quicker method commonly used in the food industry, especially in milk and juice processing.

Tyndallization is more thorough in eliminating spores, it is not commonly used in food processing due to its complexity. Pasteurization, though less effective against spores, is widely preferred in the food industry for its efficiency and ability to retain the food's original flavor and nutritional value.
