How To Tell If Tomato Sauce Is Gone Bad
Tomato sauce, regardless of whether it is homemade or commercially made, doesn’t have a long shelf life. If you want to check whether your tomato sauce is spoiled, check for any discolouration or bad odour. A bad tomato sauce may have fungus or mould growing with a pungent smell.
Canned ketchup also contains preservatives and can last long in the pantry, usually three years, but preferably 2 years or less. Frozen tomato pasta sauce can last up to 18 months, which is quite a long time.
When stored properly, an unopened jar of ketchup will usually retain its best quality for 18-24 months, although it is usually safe to use afterwards. An open jar of ketchup will be kept in the refrigerator for up to 3 days but is safe afterwards.
What is the shelf life of tomato sauce?
Properly stored in a tin or glass jar, ketchup keeps best in the pantry for about 2 years unopened. Unopened and undamaged cans of ketchup will keep for years after the expiration date, the expiration date, or the expiration date printed on the can or jar.
An unopened can of tomato juice will keep fresh for 18-24 months when properly stored. Tomatoes are safe to eat, even if expired, as long as they are stored in a cool, dry place.
