Eugene Jusselle, a 19th-century French chemist, was the pioneer who devised ketchup as a strategy for preserving tomatoes.
It wasn’t until later that he discovered that adding sugar made his product even more popular.
Does ketchup go bad?
If you’re familiar with ketchup, then you probably know that it’s one of those condiment products that can last for quite a while on store shelves.
However, if you’ve ever had an old bottle sitting around and wondered whether or not it was still edible, then we have some bad news for you!
Ketchup does indeed go bad, although the exact date varies from person to person and depends on what kind of ketchup it is.
The main reason why ketchup goes bad is because of bacteria.
Bacteria are living organisms that consume food.
When they do so, they produce acids and other types of waste products which cause the food to spoil.
This is true of any food, including ketchup.
When people make ketchup at home, they usually use tomato paste as their base ingredient.
Unfortunately, this is where the problems begin.
Tomato paste contains high levels of water, which makes it prone to bacterial growth.
As soon as your tomato paste starts to ferment, the bacteria start multiplying rapidly.
After just a few days, the ketchup will begin to smell sour and taste terrible.
Unfortunately, there isn’t much you can do about it.
You can try to keep ketchup refrigerated, but there’s no guarantee that it’ll work.
Even if you do manage to keep it fresh, the problem is that once it gets close to room temperature, the bacteria multiply even faster.
That means that within a week, your ketchup could be completely spoiled.
So, unless you want to throw out a perfectly good bottle of ketchup, you should act fast when you notice that it’s starting to smell sour.
Although ketchup can last for months, it’s best to eat it within a couple of weeks.
If you don’t, then it’s likely that the bacteria will continue to grow and create more and more waste products, resulting in a nasty batch of ketchup.
In addition, some of the acid produced by the bacteria can actually damage your teeth.
So, how long can you expect ketchup to last before it begins to go bad? It really depends on how well you stored it.
If you kept your ketchup cold enough and didn’t let it sit around too long, then you may be able to get away with leaving it on the shelf for several months without worrying.
However, if you leave it in the fridge for longer than two weeks, then you’re going to have to toss it sooner rather than later.
How can you tell if ketchup has gone bad?
It’s easy to tell when ketchup goes bad.
There are several ways you can check on its quality, including smelling it and tasting it.
If you don’t want to open up the bottle and smell it, you can also try putting some on an apple slice.
This method is most effective when you’re looking at ketchup with other ingredients such as mayonnaise.
If you have opened the bottle of ketchup, you can also take a look at the expiration date and see how long the ketchup has been sitting around.
If there isn’t any information on the label, or the date is expired, then it’s probably best to throw it out.
There are certain signs that indicate ketchup has gone bad.
First, if ketchup smells rotten, it’s definitely time to throw it away.
Second, if it tastes spoiled, it’s probably too old.
Third, if it looks moldy, it’s probably expired.
If you think your ketchup is bad, but you aren’t sure why, here are a few things to consider:
You should always check the expiration dates on food products before using them.
When you buy a lot of ketchup, it might be helpful to keep a few extra bottles around so you always have fresh ones available.

Is it safe to eat ketchup that has gone bad?
Ketchup can be easily stored for up to one year at room temperature.
However, once the expiration date passes, you should throw out any remaining ketchup and replace it with new bottles.
After that, the ketchup will start to decompose and lose its flavor, making it less desirable.
Eventually, the ketchup may get moldy and smell unpleasant.
If the ketchup is exposed to excessive heat, however, then the food safety risk increases.
For example, if the ketchup bottle is left on the stovetop too long, then the contents could become unsafe for consumption.
Also, if the ketchup is accidentally heated at high temperatures (for example, when cooking), then the ketchup may turn into an unsafe substance.
On the other hand, if the ketchup bottle is not opened frequently, then bacteria can grow inside the container and cause health risks.
Bacteria can also form inside ketchup containers if they are not properly sealed.
In this case, the ketchup may have a strong odor and contain harmful substances.
When these conditions occur, then it’s best to dispose of the ketchup rather than consume it.
This is especially true if the ketchup contains raw meat.
When ketchup goes bad, it usually tastes sour.
Some people don’t mind it, but others find it unappealing and possibly hazardous.
However, there are ways to make ketchup last longer without ruining its taste.
Read on to learn how to store ketchup so that you can enjoy it for years to come.
How long does ketchup last before it goes bad?
According to Food Safety News, ketchup can sit on store shelves for up to three years without going bad.
However, this doesn’t mean that it’s safe to eat after that period of time.
In fact, ketchup should be discarded within six months because the preservatives used to keep it fresh are no longer effective.
If you’re wondering how long ketchup lasts before it goes bad, here’s what you need to know:
What happens if you eat bad ketchup?
It’s hard to imagine, but ketchup can actually go bad.
This isn’t just an urban legend, and there are many examples out there of people who have eaten old ketchup and gotten sick from it.
In fact, some people have died because of bad ketchup.
The bacteria that causes food poisoning grow very quickly when exposed to high temperatures.
Because ketchup is so acidic, it can cause these types of bacteria to multiply quickly, which is why it’s important to keep it refrigerated at all times.
You also want to make sure that the container is sealed tightly to prevent any leaks.
If you do happen to open up a bottle of ketchup and find it looks and smells funny, don’t try to use it! Throw it away immediately and replace it with a fresh bottle.
There are plenty of great brands on the market today that won’t let you down.
If you’re worried about whether or not your ketchup is going to spoil before you get around to using it, you should probably buy a new one right now.
Don’t wait for a sale or special event to stock up on ketchup, because it’s never too early to start saving money.
How can you extend the shelf life of ketchup?
The best way to keep ketchup fresh and tasty for a long time is to store it properly.
To do this, keep the following tips in mind:
What are some creative ways to use ketchup?
There are many different uses for ketchup and there’s no reason why you should have to limit yourself to just using it on burgers, fries, and hot dogs! Here are just a few ideas:
- This is also great for dipping vegetables into too.
- You can also add some horseradish sauce to really amp up the flavor.
- If you want to make this dish healthier, try adding a splash of milk instead of water.
- Try topping them with bacon bits for extra crunch.
- Just mix equal parts tomato paste, ketchup, and water.
You can also make ketchup popsicles by melting chocolate chips, ketchup, and shortening together and then freezing it to create a fun treat for kids.
What is the difference between ketchup and tomato sauce?
Both are condiments, although they’re different enough that you may not be able to tell them apart from each other just by looking at their packaging.
Both have the same basic ingredients (tomatoes, vinegar, salt, spices, water) and both can be used on anything from burgers to chicken wings to pasta.
The main differences between the two are how they’re prepared and what else they might contain.
Tomato sauces tend to be thicker than ketchups, which makes them better for thickening soups and stews.
They also usually contain less sodium and more sugar than ketchups.
Tomato sauces are often cooked down with herbs and spices before being bottled, while ketchups are strained and then bottled.
This gives tomato sauces more flavor and longer shelf lives than ketchups.
While there’s no hard and fast rule about when one stops being called “ketchup” and starts being called “tomato sauce,” most people know the difference between the two.
However, some brands of tomato sauce claim to be ketchup, so be careful when purchasing it.
If you’re unsure whether or not a particular brand of ketchup is going to last you a long time, you should probably buy it in smaller quantities rather than buying a large bottle.
You’ll need only a small amount of ketchup per serving, so you won’t end up wasting much money.
Also, if you buy a large bottle of ketchup, you may find yourself using it up too quickly.
