It is common to sterilize and/or pasteurize screw-top glass jars, also called twist-off jars. Do you know the difference between sterilization and pasteurization and what’s involved in each technique?

What are the differences between pasteurization and sterilization?
Pasteurization and sterilization have the same objective: to preserve food
Pasteurization destroys some of the germs present in food and
prevents any remaining germs from proliferating. The food is heated
to a temperature between 62°C and 88°C for a specific period,
followed by rapid cooling.
Sterilization destroys all the germs in the food, including
microbial spores. The food is raised to a high temperature, always
greater than 100°C (usually around 120°C).
Remember to check that each product (jar, lid, etc.) can withstand the temperatures necessary for sterilization or pasteurization. If you’re not sure, please contact our Ebottles experts.
How to avoid contaminatingthe twist-off lid?
The glass jar should not be overfilled to avoid contaminating
the lid with the contents.
For example, for a small glass jar with an overflow capacity of 580ml:
- For pasteurization, a headspace of roughly
5%is required; so it must not be filled to more than 551ml, which
is 5% less than the overflow capacity
- For sterilization, a headspace of roughly 9%
is required; so it must not be filled to more than 527ml, which is
9% less than the overflow capacity
