Tyndallization vs. Pasteurization: Know the Difference
By Shumaila Saeed || Published on January 5, 2024
Tyndallization is a sterilization method involving intermittent heating, while pasteurization is a process of heating food to kill harmful microorganisms.
Key Differences
Tyndallization involves heating substances intermittently over three days to sterilize them, targeting heat-resistant spores. Pasteurization involves heating a substance (usually liquid) to a specific temperature for a set period to eliminate pathogens.

In Tyndallization, the substance is heated to boiling temperatures intermittently over a few days. Pasteurization typically heats substances to temperatures below boiling (around 60-85°C) for shorter periods, like 15-30 minutes.

Tyndallization aims at complete sterilization, including destruction of heat-resistant bacterial spores. Pasteurization's goal is to reduce microbial load to safe levels, not necessarily achieving complete sterilization.
