Eggs in the fridge? mayo? Wine? Only some products were in one household’s refrigerator and none in the other household’s refrigerator. Not a question that determines everything in life, but something that everyone who buys this product has probably asked.

‘Can not be trusted’

You can also discuss ketchup. And it happened in a big way last week. Every now and then it comes back. For example, rapper Cardi B. once stated on Twitter: “You can’t trust a person who keeps ketchup in the fridge.”

The claim cannot be proven, but the question of what is best can be answered.

For ketchup manufacturer Heinz, this is very clear: ‘FYI: Soy sauce. go. in the. That. refrigerator!!!.’ With this tweet, the American sauce brand hopes to settle this discussion once and for all. So in the fridge.

In any case, Heinz’s tweet of course became fodder for supporters and opponents to pour new sauce into the discussion. Reasons for quality newspapers Washington Post to devote an article to it, in which the author is surprised that the man with whom he has been for 18 years prefers to keep ketchup in the kitchen. “Why would I want to put cold tomato sauce on hot food” is a common argument for not storing it in the refrigerator.

The ‘Fridge Team’ argument is not about taste but about shelf life. Of course, there’s no debate about taste, but there is something reasonable to say about the shelf life of sauces. A call to the Nutrition Center will provide insight.

“It’s best to store tomato sauce in the refrigerator after opening,” says Pascalle Stijger of the Nutrition Center getting straight to the point. “If you open it and then put it in a cupboard, oxygen can be added and bacteria have a better chance. It has a longer shelf life in the refrigerator, about nine to twelve months.”

Not in the refrigerator at the supermarket

It’s not unreasonable for it to be on the outside of the refrigerator in the supermarket. The lid fits tightly to the lip, so it has a longer shelf life, Stijger said. Heinz itself also advertises that ketchup has a long shelf life. For the sake of clarity, they add that it should be stored unopened in the refrigerator.

Stijger points out that the expiration date that must be listed on all products applies to unopened products, something not everyone knows. So, if you’re a fan of ketchup and go through a bottle of ketchup every week (also not necessarily recommended, says the Nutrition Center), it’s best to store it out of the refrigerator. However, normal people are advised to store the sauce cold.

Something Heinz now so fully agrees with that its UK branch is raffling off fridges among its supporters ‘to put ketchup in’:

As a bonus for those who have read this article in its entirety, Pascalle Stijger also tells you what to do with eggs: “Eggs are in supermarkets outside the refrigerator compartment, but once you get home, it is advisable to store them in the refrigerator. ” This is related to condensation caused by temperature differences that occur during the transportation of eggs from the supermarket to the house. This condensation creates bacteria, which you can prevent by refrigerating it at home. .”
