What is canning
Canning is a food preservation method that has been used for centuries. It involves sealing food in jars or cans and then heating them to destroy any bacteria and enzymes that can cause spoilage. This process allows food to be stored for long periods of time without the need for refrigeration. Canning can be done using different methods, such as water bath canning or pressure canning.
Water Bath Canning
Water bath canning is a method that is suitable for high-acid foods, such as fruits, pickles, and chutneys. In this method, the jars are filled with the prepared food and then submerged in a large pot of boiling water. The jars are heated until the contents reach the appropriate temperature to kill any bacteria. Once the jars are removed from the pot, they cool and create a vacuum seal that keeps the food preserved.
Pressure Canning
Pressure canning is necessary for low-acid foods, such as vegetables, meats, and poultry. These foods need to be processed at higher temperatures to eliminate the risk of botulism, a serious foodborne illness. Pressure canning involves using a pressure cooker or canner that allows the contents to reach a temperature of 240°F (116°C). This high heat destroys any potential bacteria and preserves the food inside the jars.
Canning is a great way to preserve the freshness and flavors of garden produce. By following proper canning procedures, you can enjoy your own homemade canned goods throughout the year.
