Canning vs freezing – preserving methods compared
Canning and freezing are two common ways to keep food for later. Canning has many steps and takes time, based on what you’re canning. It’s been used for a long time and keeps food fresh while saving nutrients. Freezing, by contrast, is simpler and quicker to pick up. But, it uses a lot of power because the freezer runs all day to keep food cold. This high energy use is a downside. Also, freezing can change how some foods feel, making them less enjoyable. If you don’t pack foods the right way before freezing them, you might end up with freezer burn. This can make the taste and texture worse because of moisture loss and air exposure.
Both canning and freezing work well for keeping food safe and available longer. Water bath canning is good for fruits, jams, and pickles because it’s safe and keeps their taste and texture nearly the same. But it needs special gear and is slow. On the other hand, when you need to can vegetables, meats, or soups, you must use a pressure canner to prevent botulism. Canned food can last over a year if stored in a cool, dark spot.
