The ongoing discussion: Where does the public stand?

Every week on social media platforms like Twitter, there's a heated debate about whether ketchup belongs in the cupboard or the fridge that rivals the intensity of even the most passionate bread-ending discussions. According to unscientific polls on Twitter, the public appears to be split down the middle. A slightly higher percentage of people tend to keep ketchup in the refrigerator.

Opinion poll

Where do you keep your tomato ketchup?

In the fridge or not, it's in a cupboard where it should be, really cold ketchup is not necessary

In an interesting turn of events, a survey by ketchup maker Heinz found that about 58 percent of respondents preferred to store their ketchup in the refrigerator, while the remaining 42 percent preferred the pantry

In contrast, a slightly more scientific survey found that 56 percent of Brits keep their ketchup in the pantry. As the old saying goes, “Don’t trust the British,” meaning the “right” place is the fridge.

Understanding the science behind ketchup storage

Ketchup can often be found on the unrefrigerated shelf of the grocery store along with other condiments such as mayonnaise. This leads many to believe that it is perfectly fine to store these spices at room temperature. However, there is more to it than meets the eye.

Before vacuum sealing, both ketchup and mayonnaise are sterilized so they can be safely stored at room temperature until opened. Once mayonnaise is opened, it begins to spoil due to its egg content. Unlike mayonnaise, ketchup will not spoil if stored out of the refrigerator due to its high acidity, sugar and salt content.

Although ketchup doesn't become harmful if left in the pantry - ketchup was around before refrigerators were even invented - it can develop a different flavor and change color when it's there. Safe consumption does not necessarily result in a pleasant dining experience. Why not treat your taste buds to ketchup, which hasn't developed an unusual new flavor due to its proximity to canned beans?

When should you keep ketchup in the pantry?

Ketchup owes its high acidity to its two main ingredients: tomatoes and vinegar[^6^]. Along with a generous amount of salt and sugar, which are natural preservatives, these ingredients preserve ketchup, according to the United States Department of Agriculture (USDA).

For this reason, many diners and burger joints leave their ketchup bottles at room temperature. They're safe to store in an airtight container in the pantry, but there's a catch. If you plan on using the entire bottle of ketchup within a few days, you can safely store it in the pantry. Otherwise, it's best to opt for the refrigerator.

Arguments for storing ketchup in the refrigerator

Your ketchup consumption plays a crucial role in determining whether it belongs in the pantry or the refrigerator. If you finish a bottle within a few days, the pantry is your friend. However, if you need a month or more to finish a bottle, the fridge is the place to be.

The main reason is the gradual decline in flavor and texture after you open the bottle or jar and the ketchup is exposed to air. Similar to cucumbers, exposure to air can dull the flavor over time. To slow this process down significantly, store your ketchup in the refrigerator. This ensures that your ketchup retains its salty, savory, sweet, tangy and perfectly tomato flavor for longer. According to the USDA, ketchup can be stored in the refrigerator for about six months after opening.

Heinz's verdict on the debate

The authority on ketchup, Heinz, waded into this debate a few years ago. They stated that “Heinz® Ketchup is shelf stable due to its natural acidity.” However, the stability after opening may be affected by storage conditions. We recommend storing this product, like all processed foods, in the refrigerator after opening. Cooling ensures the best product quality is maintained after opening.”

Unless you're a ketchup fanatic and plan on using an entire bottle within a short period of time, Heinz, along with many other experts, apparently recommends storing ketchup in the refrigerator.

Other factors to consider

In addition to the points discussed above, you should also consider your climate and the temperature of your kitchen. If you live in a hot, humid environment, you may want to store your ketchup in the refrigerator to extend its shelf life and maintain its flavor profile.

Another consideration is the serving temperature. If you're making a hot plate of homemade french fries, you might prefer cool ketchup from the fridge, which provides a lovely temperature contrast. On the other hand, if your food is at room temperature or cooler, pantry ketchup might suit you better.

Additional tips for storing and using ketchup

• Verwenden Sie immer einen sauberen, trockenen Löffel oder drücken Sie ihn aus der Flasche aus, um zu vermeiden, dass Bakterien in Ihren Ketchup gelangen.
• Achten Sie auf die Farbe und den Geruch Ihres Ketchups. Wenn es anfängt, dunkler zu werden oder einen unangenehmen Geruch zu entwickeln, ist es wahrscheinlich an der Zeit, es wegzuwerfen.

• Wenn Sie eine Glasflasche verwenden, schütteln Sie diese vor der Verwendung gut, um sicherzustellen, dass die Zutaten gut vermischt sind.
• Versuchen Sie, keinen Ketchup in großen Mengen zu kaufen, es sei denn, Sie sind sicher, dass Sie ihn innerhalb der empfohlenen Zeit aufbrauchen können. Denken Sie daran, dass es für den besten Geschmack immer am besten ist, frische Gewürze zu sich zu nehmen.

Health Benefits of Ketchup

Although ketchup is not typically considered a health food, it does have some nutritional benefits when consumed in moderation:

1. Lycopene

   : Ketchup is rich in lycopene, a powerful antioxidant that has been linked to a reduced risk of heart disease and cancer.

2. Vitamin C

   : As a tomato-based product, ketchup is a good source of vitamin C, which is important for immune function and skin health.

3. Vitamin A

   : Ketchup contains vitamin A, which supports eye health and strengthens the immune system.

4. Low calories

   : Ketchup is relatively low in calories at just 19 calories per tablespoon, making it a good option for anyone watching their calorie intake.

"When we think of ketchup, we associate it with tomatoes. However, store-bought ketchup contains more harmful ingredients that should be avoided at all costs. Ketchup is full of salt, but also sugar - one tablespoon of ketchup contains about a teaspoon of sugar, which is a lot when you consider that the recommended daily intake of sugar for adults is about 21 grams," warns Dr. Kristina Hendija.

Ketchup's basic ingredients might not be so bad for you, but when you add additives to give your favorite condiment its distinctive flavor, things change. "While the ingredients are generally healthy (tomatoes, onions, vinegar), they are unfortunately full of HFCS = high fructose corn syrup. This is a processed sugar that has been linked to many cardiovascular problems," explains registered dietitian Alexandra Soare. “Other ketchup companies use sugarcane instead of HFCS, but this doesn’t completely solve the problem as the amount of sugar is still quite high.” Bottom line, it's important to use it in moderation or, like I do, choose an organic brand with low or no sugar content. It's a little expensive, but worth it for me. Check out the video below for a great recipe for making your own sugar-free ketchup.

While ketchup is safe to store in the pantry for short periods of time due to its high acid and preservative content, the consensus is to store it in the refrigerator for a longer period of time after opening. This not only helps preserve the taste and texture of the ketchup, but also provides a better gastronomic experience. This guide can help you make an informed decision based on your ketchup consumption habits and personal preferences and settle the "ketchup in the pantry or in the fridge" debate once and for all.
