The Difference Between Natural vs. Regular Peanut Butter

Ingredients in regular vs. natural peanut butter

When it comes to peanut butter, there are two main types: regular and natural. The primary difference between the two lies in their ingredients.

Regular peanut butter typically contains peanuts, oil (such as hydrogenated vegetable oil), sugar, and salt. These additional ingredients help to stabilize the peanut butter, prevent separation, and enhance its flavor.

On the other hand, natural peanut butter is made solely from peanuts and may contain a small amount of salt. It does not contain any added oils or sugars. This minimal ingredient list makes natural peanut butter a popular choice for those looking for a healthier option.

Why natural peanut butter separates

One common characteristic of natural peanut butter is its tendency to separate. This separation occurs when the natural peanut oils rise to the top, leaving a layer of solids at the bottom of the jar. While this may seem like an inconvenience, it is actually a natural process and a sign that the peanut butter is free from additives.

The separation in natural peanut butter can be easily remedied by stirring the contents of the jar. Some natural peanut butter brands may also suggest refrigerating the product to slow down the separation process.

So, why does natural peanut butter separate? The answer lies in its lack of stabilizing ingredients. Without added oils and emulsifiers, the peanut oil is free to separate from the solids. This is not a cause for concern and does not affect the taste or quality of the peanut butter.

It’s important to note that refrigerating natural peanut butter may make it harder to spread, as the cold temperature can cause the peanut oil to solidify. If you prefer a softer consistency, you can store it at room temperature. However, if you live in a warm climate, refrigerating natural peanut butter can help extend its shelf life and prevent spoilage.

Signs Your Peanut Butter Has Gone Bad

When it comes to peanut butter, it’s important to know when it has gone bad. Here are some signs to look out for:

Change in texture

If you notice that your peanut butter has become dry, crumbly, or has developed a grainy texture, it may be a sign that it has gone bad. Fresh peanut butter should have a smooth and creamy consistency, so any changes in texture could indicate spoilage.

Rancid smell or taste

An obvious sign that your peanut butter is no longer good is if it has a rancid smell or taste. If it smells off or has a bitter or sour taste, it’s time to toss it out. Rancidity occurs when the natural oils in the peanuts start to break down, resulting in an unpleasant odor and flavor.

Mold growth

One of the most obvious signs of spoilage is the presence of mold. If you see any green, black, or white fuzzy spots on the surface of your peanut butter, it’s best to discard it immediately. Mold can produce toxins that are harmful if ingested, so it’s not worth the risk.

Remember, if you’re unsure whether your peanut butter is still good, it’s better to be safe than sorry. It’s always a good idea to check for any signs of spoilage before consuming it.

Does Natural Peanut Butter Need Refrigeration?

When it comes to natural peanut butter, the answer to whether it needs refrigeration is not a straightforward one. It depends on the type of natural peanut butter you have – pure peanut butter or peanut butter with added oil.

For pure peanut butter, no

If you have pure peanut butter that contains only peanuts and maybe a pinch of salt, you do not need to refrigerate it. Natural peanut butter without added oil can be stored at room temperature for several months. However, it is important to store it in a cool, dry place to prevent the oil from separating.

When you first open a jar of natural peanut butter, you may notice that the oil has separated and risen to the top. This is completely normal and is a result of the absence of hydrogenated oils or stabilizers. To incorporate the oil back into the peanut butter, simply give it a good stir before each use.

For peanut butter with oil, yes

If your natural peanut butter has added oil, such as palm oil or vegetable oil, it is recommended to refrigerate it. The added oil helps to stabilize the peanut butter and prevent the separation of oil. Refrigeration keeps the oil from going rancid and extends the shelf life of the peanut butter.

Refrigerating peanut butter with oil also helps to maintain its consistency and makes it easier to spread. However, keep in mind that refrigerated peanut butter may become harder and less creamy, so you may need to let it sit at room temperature for a few minutes before using.

Ultimately, whether or not you refrigerate your natural peanut butter depends on your personal preference and how quickly you consume it. If you tend to go through a jar of peanut butter within a couple of weeks, storing it at room temperature should be fine. However, if it takes you longer to finish a jar or if you live in a warm climate, refrigeration may be a good option to keep your peanut butter fresh.

The Pros and Cons of Chilling Peanut Butter


Chilling organic peanut butter has several advantages that you should consider:

  • Extended Shelf Life: Refrigerating organic peanut butter can help prolong its shelf life by preventing the growth of bacteria and mold. This is especially important if you don’t consume peanut butter frequently and want to ensure it stays fresh for longer.
  • Enhanced Spreadability: Cold temperatures can make the peanut butter slightly firmer, making it easier to spread on bread or crackers without it becoming too messy. This can be particularly beneficial if you prefer a thicker consistency.
  • Reduced Oil Separation: Organic peanut butter tends to have natural oil separation, where the oil rises to the top. Refrigerating it can help minimize this separation, resulting in a more consistent and easier-to-use product.
  • Added Cooling Sensation: Some people enjoy the refreshing and cooling sensation that chilled peanut butter provides. It can be a delightful treat, especially during hot summer months.


While there are benefits to refrigerating organic peanut butter, there are also a few downsides to consider:

  • Harder Texture: When refrigerated, peanut butter can become harder and less creamy. If you prefer a softer and smoother texture, you may find that refrigerating it alters the overall mouthfeel of the spread.
  • Delayed Spreadability: Cold peanut butter can be more challenging to spread, especially if you keep it in the refrigerator for an extended period. This can be inconvenient if you’re in a rush or simply prefer a spread that glides easily.
  • Potential Flavor Alteration: Refrigeration can slightly affect the taste of organic peanut butter. Some people may find that the cold temperature dulls the flavor or alters the overall taste profile. However, this is subjective and may vary from person to person.

Ultimately, whether you choose to refrigerate your organic peanut butter or not depends on personal preference. Consider the factors mentioned above and decide what works best for you. If you’re unsure, it’s always a good idea to consult the manufacturer’s recommendations or visit reputable sources like Healthline or Eat This, Not That! for more information.

How to Store Peanut Butter Properly

Pantry storage tips

Proper storage is crucial to maintain the freshness and quality of your organic peanut butter. If you prefer a smooth and spreadable consistency, storing it at room temperature is the way to go. When kept in the pantry, organic peanut butter can last up to three months, making it easily accessible for your daily PB&J sandwiches or as a delicious dip for your favorite fruits and veggies.

However, it’s important to note that natural separation can occur in organic peanut butter. The oil might rise to the top, leaving a layer of oil on the surface. To prevent this, simply store the jar upside down for a day or two to redistribute the oil. This will help maintain a creamy texture throughout.

Remember to always tightly seal the jar after each use to prevent moisture and contaminants from entering. This will also help extend the shelf life of your organic peanut butter.

Refrigerator storage tips

If you live in a hot and humid climate or if you don’t consume peanut butter frequently, refrigeration might be a better option for you. By refrigerating organic peanut butter, you can extend its shelf life up to six months.

Refrigeration can cause the peanut butter to harden and become less spreadable, but don’t worry! All you need to do is let it sit at room temperature for a few minutes before using. This will help soften it up and make it easy to spread once again.

It’s worth noting that refrigeration can also help prevent the natural oils from separating, which means less stirring required before each use.

However, if you prefer a softer and creamier consistency, refrigeration may not be the best choice for you. In that case, it’s best to stick with pantry storage.

So, should you refrigerate organic peanut butter? Ultimately, it depends on your preference and how quickly you consume it. If you use it regularly and prefer a smooth texture, storing it in the pantry is a great option. On the other hand, if you live in a warm climate or don’t use it frequently, refrigeration can help prolong its shelf life.
