Name one common way to preserve food.

Canning is a common method of preserving food because it involves sealing food in containers, usually jars or cans, and heating them to a temperature that kills harmful bacteria, yeasts, and molds. This process not only extends the shelf life of food but also helps retain its nutritional value and flavor. The airtight seal prevents new microorganisms from entering and spoiling the food, making it a reliable preservation technique that can allow foods to be stored safely for months or even years.

Frying, grilling, and baking, while popular cooking methods, do not effectively preserve food for long-term storage. Instead, these methods transform the food through cooking, but without proper preservation techniques, the food will spoil quickly.
