Quick Answers
I've heard that if aspirin is added to home-canned vegetables no processing is needed?
There is no safe ingredient that could destroy
microorganisms and extend shelf life of food like heat
processing does. Aspirin does contain a weak germicidal
agent that is needed as a preservative for the aspirin
compound. This agent is not adequate for preventing food
spoilage in canned foods. Also, aspirin will not stop
enzyme action that causes loss of food quality. In
addition, without proper heat processing, no vacuum is
formed, and contamination of the food product can occur.

You Start to Can, Learn the Basics" GH 1451.
