Does Butter Go Bad If You Don’t Refrigerate It?

Butter is a preferred spread and also cooking active ingredient.

Yet when you store it in the refrigerator, it comes to be difficult, so you require to soften or melt it before usage.

Consequently, some people save butter on the counter rather than in the refrigerator.

Yet does butter go bad if you leave it out? This article discovers whether it really needs to be refrigerated or not or stored in a butter dish with lid.

Butter is a dairy item, meaning it is made from the milk of animals– typically cows.

It is made by churning milk or lotion up until it divides into buttermilk, which is mostly fluid, and also butterfat, which is mostly solid.

Butter is unique amongst dairy products due to its extremely high fat content. While entire milk consists of simply over 3% fat and heavy cream consists of nearly 40% fat, butter has more than 80% fat. The staying 20% is mainly water.

Unlike various other dairy products, it doesn’t contain several carbohydrates or much protein.

This high fat web content is what makes butter so thick as well as spreadable. However, when it is kept in the fridge, it ends up being difficult as well as hard to spread.

This leads some individuals to store butter at area temperature level, which maintains it at the excellent uniformity for food preparation and spreading.


Butter has a high fat content of over 80%, that makes it thick as well as spreadable. The rest is primarily water.

Because butter has a high fat material and relatively low tide material, it is much less likely to sustain microbial growth than various other sorts of dairy products.

This is especially true if the butter is salted, which reduces the water web content additionally as well as makes the atmosphere unwelcoming to microorganisms.
Salted Ranges Resist Microbial Growth

According to the United States Food and Drug Administration (FDA), while a lot of sorts of microorganisms would have the ability to survive on saltless butter, there is only one type of germs that can make it through the conditions of salty butter.

In one study to establish the life span of butter, researchers included numerous types of bacteria to the butter to see exactly how well they would grow.

After 3 weeks, the bacterial content was significantly lower than the amount included, demonstrating that butter doesn’t support most bacterial growth.

Therefore, routine, salty butter has a reduced threat of microbial contamination, also when maintained area temperature level.

As a matter of fact, butter is really produced with the assumption that consumers will not maintain it in the fridge.

However, saltless as well as whipped kinds are a various story.
However Don’t Let Your Butter Go Rancid

Although butter has a reduced danger of microbial growth, its high fat web content implies it is prone to going rancid. When a fat spoils, you can tell it should no longer be eaten since it will smell and also might be tarnished.

Fats go rancid, or ruin, with a process called oxidation, which changes their molecular structure and produces possibly dangerous substances. It additionally causes off tastes in any type of foods made with the rancid fats.

Heat, light and also direct exposure to oxygen can all speed up this procedure.

Yet it has actually been shown that it might take anywhere between numerous weeks to over a year for oxidation to adversely influence butter, depending upon how it is created as well as saved.


Butter’s structure inhibits bacterial growth, also at area temperature. However direct exposure to light, warm and oxygen can trigger rancidity.
