How Long Does Ketchup Last?
Now we know that ketchup – indeed – goes bad, we have to ask the question, how long would it last before it spoils? the answer isn’t as straightforward as you think.

Homemade ketchup can be stored in the refrigerator for up to three weeks after it is prepared, while store-bought ketchup will depend on the bottle condition.
Ketchup bottles last for a year when unopened, while opened bottles last for three months when refrigerated.
It’s important to note that as long as ketchup is stored properly in a cool place, there is no need to throw it out just because the flavor has changed or the color has darkened. The change in flavor and color are natural processes that happen when food interacts with oxygen over time.

How To Store Ketchup?
One of the key advantages of ketchup over other condiments is that it can be stored for longer periods of time.
This means you can stock up on large quantities, without having to worry about the quality deteriorating. However, there are some measures you should take to ensure your ketchup remains at its best.
All you need to do is keep it in a cool, dry place away from direct sunlight. Refrigeration is not necessary for ketchup because the vinegar and salt in the condiment are both natural preservatives that prevent it from spoiling. However, refrigeration would increase the shelf life of opened ketchup bottles.
Here is a good tip to prevent contamination: be sure that you keep the bottle cap clean.
Just wipe any build-up off of the cape bottle, and make sure it’s dry before closing the bottle back. This will keep your ketchup longer after each and every use.

How To Tell If ketchup Has Gone Bad?
Even with optimal storage, things can go bad and your ketchup might spoil. The question is how to tell if your ketchup is spoiled or not?
ketchup goes bad when it is exposed to air and moisture. As a general rule, ketchup should be discarded if it develops an off odor, flavor, or appearance.
It can become contaminated with harmful bacteria such as listeria and E-coli from the time it leaves the factory until you bring it home.
Therefore, you should always check the “Use By” date on the label before buying or using any condiments.
There are three ways to tell if ketchup has gone bad, they are smell, look, and taste.
Smell
In truth, spoiled ketchup smells just as bad as spoiled tomatoes. In fact, the only difference is that the scent is somewhat more concentrated than that of tomato juice. In both cases, you will notice a pungent odor wafting from the bottle if they have been left out for a long time.
Look
Though you might not be able to tell if the ketchup has spoiled just by looking at it. If there’s a chance that your ketchup may have gone. This is because spoiled ketchup will look similar to natural one but it will have a different texture and color.
Natural ketchup is red in color and looks smooth. Spoiled ketchup is also red in color but the consistency is thicker than normal and fresh variant.
A cloudy bottle is also a sign of spoiled ketchup, so, stay on the lookout for it as well. Trust your eyes and senses when trying to determine if something has gone bad or not.
Taste
If it looks good and smells good, it doesn’t necessarily mean it would be good. This means you could have spoiled ketchup without the above two signs, which can be detected through taste.
Spoiled ketchup tastes a lot different from fresh ketchup. Spoiled ketchup is a lot more tangy and sour than the fresh variant, due to the decomposition of the tomato paste, which normally gives it that sweet taste.
