Canned tomatoes are a pantry staple for many home cooks, but how long can you keep them in your cupboard before they go bad? Understanding shelf life and proper storage for canned tomatoes is key to ensuring that your dishes are always fresh, flavorful, and safe to consume. In this blog, we’ll explore the answers to the question, “How long do canned tomatoes last?”
How Long Do Canned Tomatoes Last?
Canned tomatoes have always been a staple in the pantry, providing a convenient and affordable way to add flavor and nutrition to any meal. But, how long do canned tomatoes last?
The shelf life of canned tomatoes depends on several factors, including the type of tomatoes, the canning method, and the storage conditions. Generally, canned tomatoes can last for up to 18 months when stored in a cool, dry place. However, you may notice a slight decrease in flavor and texture after the expiration date.
The type of tomatoes you use can also determine the shelf life. Canned whole tomatoes are generally more stable than diced or crushed tomatoes. Whole tomatoes can last up to two years if stored properly. On the other hand, diced or crushed tomatoes can last up to six months.
The canning method also impacts shelf life. Tomatoes canned with added sugar and acid (tomato sauce, salsa, and ketchup) can last up to three years if stored properly. Tomatoes canned with just salt and water will only last up to one year.
Finally, storage conditions can affect how long canned tomatoes last. Canned tomatoes should be stored in a cool, dry place. Avoid storing canned tomatoes in direct sunlight or any area with high humidity. Extreme temperatures can also cause the cans to expand or burst, so avoid storing them in the freezer.
To keep canned tomatoes fresh for as long as possible, always check for expired dates and look for any signs of spoilage, such as dents, rust, bulging, or off-odor. Never consume canned tomatoes that have been left out of the refrigerator for more than four hours.
