What kind of chemistry is involved in canning?

Answer 1

There can be any number of processes going on. It depends on the process of canning used. Pickling, jamming, jellying, relishing, simple preserves, these are all canning processes. The chemistry of some is quite simple, while that of others is more complex.

Answer 2

The chemistry involved in canning primarily focuses on achieving proper pH levels to prevent bacterial growth, as well as heat processing to kill microorganisms that could spoil the food. Acids like vinegar are commonly used to lower the pH, creating an environment that inhibits bacterial growth, while high heat during processing helps destroy any existing microorganisms. Additionally, the interaction between the food and the container material can also impact the overall quality and safety of the canned product.
