Short answer….no. Although some manufacturers indicate that their product can safely pressure “can” foods, the USDA has not endorsed this method. From the USDA: “We do not know if proper thermal process development work has been done in order to justify the canning advice that is distributed with these pressure multi-cooker appliances.” The concern is for the temperature inside the jars of food.
Do you keep it or throw it out? In the United States, people throw away 30-40% of the food they buy. Are we throwing food away unnecessarily? Perhaps. If you are using the dates stamped on food products as your guide, then you might need to revisit your strategy. So, what do those numbers mean?
