How To – Food Acidity Level Reference for Canning

There are a variety of foods that are available in stores that most home canners may want to process. Understanding the acidity level of the food you are preparing is very important for longevity in storage and for safety.

Normally standard boiling in a water bath for canning requires that you use either a high acid food like lemons or add acid to the food before canning such as pickled cucumbers.

This list will give you a General guide that you must verify with supplemental information. For instance if you are processing tomatoes that can sometimes be processed in a water bath whole but preferably are canned in a pressure cooker canner you should measure the PH level of the food yourself then PLEASE use another guide to ensure the method you choose is best for you… Again this is only a quick guide and should not be your only resource for processing foods.
