Pressure canning at home

Asked January 10, 2019, 9:27 PM EST

I made a large volume of my husbands favorite soup and he would like me to can it, as we don't have adequate freezer space. It contains vegetable broth, carrots, celery, garlic, onion, cabbage, kale, corn, tvp and rice. Is it possible to can it and do it using a Power Pressure Cooker XL?
Thank you

Unfortunately it is not possible to can that soup- although it sure looks good. There are no safe home canning instructions for any soups with rice or tvp in them. The soup also looks very thick. Those ingredients and the thickness of the soup would make it very difficult to ensure that the entire product heated through during processing. Any remaining cold spots would be likely environments for botulism and other pathogens. The internal temperature of the contents would need to reach well above boiling to ensure safety.

We always recommend that people start with a recipe meant for canning. You can find a basic soup recipe here: https://nchfp.uga.edu/how/can_04/soups.html When you open the jars, you can add the rice, tvp, dairy products to make it into the final product that you wish.

At this time USDA and Extension Service are strongly recommending against any attempts to can in an electric pressure cooker, regardless of what their instructions say. In our experience, the vessels do not maintain the required internal temperatures throughout the entire processing time, they heat up too quickly and cool too quickly for adequate processing. https://nchfp.uga.edu/publications/nchfp/factsheets/electric_cookers.html

I realize this isn’t what you were hoping for, but I’m glad you asked, so that you can make decisions to keep your family safe.
