What is pressure canning and how does it work?
Pressure canning is a method of canning that uses high pressure to kill off bacteria and other microorganisms that can cause spoilage. It works by heating the food to a high temperature, typically around 240°F (115°C), and then sealing it in airtight jars or cans. The pressure from the heat creates a vacuum seal that prevents new contaminants from entering the jar.
The pressure canner itself is a large pot with a locking lid that allows you to control the pressure inside. You add water to the canner, place the jars inside, and then close the lid. As the water heats up, the pressure builds, and the temperature inside the canner rises. This process is essential for killing off bacteria like Clostridium botulinum, which can cause botulism.
Is pressure canning kimchi safe?
Pressure canning kimchi is safe as long as you follow tested recipes and guidelines. Kimchi is a high-acid food, which means it has a natural acidity that helps to preserve it. However, it’s still important to use a pressure canner to ensure that the kimchi is heated to a high enough temperature to kill off any bacteria that may be present.
When pressure canning kimchi, it’s essential to use a tested recipe that has been specifically designed for pressure canning.
