When canning, the pH does not kill botulism. Rather, a pH less than 4.6 is needed to prevent botulism from growing.

If you are canning foods with a pH at or over 4.6, a pressure canner is needed to completely kill botulism.

What is the significant of pH in foods?

Low pH foods tend to taste sour. High pH foods taste bitter. Low pH foods can be canned using either boiling water baths or pressure canning. Sufficient acidity (low pH) can prevent botulism spores from germinating. High pH foods require pressure canning (which reaches higher temperatures) in order to kill any botulism spores.

Can you preserve leftovers by canning them in your canner?

You should not in most cases. Canning foods is really a science of combining specific amounts of ingredients to achieve a product that meets a necessary ph level required to preserve the food. If the ph level is not acidic enough the food will develop botulism and can kill you. It is not always easy to detect the presence of botulism in food so following recipes that have been tested in kitchens approved by the USDA is very important. Please do not experiment with canning foods.


What is the pH of stomach?

How can I ensure that the temperature is high enough to kill botulism when preparing food?

To ensure that the temperature is high enough to kill botulism when preparing food, you should follow proper cooking guidelines and use a food thermometer to ensure that the food reaches a temperature of at least 185F (85C) for a sufficient amount of time. This will effectively destroy the botulism toxin and prevent foodborne illness.
