Does Ketchup Need To Be Refrigerated?

Does ketchup need to be refrigerated? The answer is no, but yes.

The case for the pantry

In terms of safety, there’s no real need to refrigerate ketchup. Tomatoes and vinegar, the main components in ketchup, help preserve the condiment at room temperature due to their natural acidity. Warm ketchup won’t make you sick and won’t necessarily spoil, but you may notice changes in color (thanks, oxidation), smell and taste once it’s been opened and hanging in the pantry for a month or so.

So, if you prefer your ketchup warm, go ahead and leave it on the pantry shelf. Just be sure to use it up before it gets a color or scent you’ll find unappetizing. But if you want your ketchup to look and taste just like the first time you used it, pop the bottle in the fridge to maintain its quality.

The case for the fridge

According to Heinz, the best way to store ketchup is in the refrigerator. The company says on its website: “Because of its natural acidity, Heinz Ketchup is shelf-stable. However, its stability after opening can be affected by storage conditions. We recommend that this product be refrigerated after opening to maintain the best product quality.”

Refrigerating ketchup will extend its shelf life and prevent any deterioration in flavor and texture. Ketchup will last for a year in the pantry if unopened, but once it’s been opened and unavoidably exposed to air, its quality will start deteriorating if it isn’t refrigerated. If chilled, however, an opened bottle of ketchup can last for up to six months.

What about restaurants?

You may have noticed that restaurants and diners seem to keep open bottles of ketchup on their tables all day and night long. How do they get away with it? Well, they don’t. They’re actually dumping the bottle contents into the trash each night. They also go through those table bottles way faster than one family or person would. But they’re also filling those bottles for single-day use from a massive bulk container of ketchup that’s kept— gasp —in the refrigerator.

The verdict

The bottom line is that you need to store open ketchup containers in the fridge, no ifs, ands, or burgers about it. It’s not only safer but also tastier. Unless you’re a busy diner going through and refilling ketchup bottles every day or two, you should store your ketchup in the fridge. This is because, just like pickles, the flavor and texture declines after you open the bottle or jar and the ketchup is exposed to air. To slow down this process way down, stash it in the fridge.
