Peanut butter is often regarded as one of the greatest nonperishable, no-cook meals to have on hand in an emergency (don’t believe me, Google it)…
It’s simple to have on hand for your 30-day emergency food storage. But it is not always the greatest choice to stockpile big quantities of food in advance of a disaster. This leads us to the question: how to long-term? After doing the research, here’s what I uncovered…
Best Method: In the cupboard, an open jar of peanut butter will remain fresh for up to three months if stored properly. It is advised that you keep the peanut butter in the refrigerator (where it can maintain its quality for another 3-4 months). Oil separation can occur if the container is not refrigerated.
After conducting more investigation, I discovered additional facts that you should be aware of, so please continue reading…

Is it okay to eat peanut butter that has gone bad?
FYI: Eating expired peanut butter, even if it is several years old, is typically considered harmless…
Although the peanut butter may have gone rancid and developed a terrible flavor, it will not cause food poisoning if consumed properly.
Some people, however, may have stomach discomfort as a result of consuming rotten food. In addition, rancid peanut butter will not have as many nutrients as fresh peanut butter does.
It is possible that peanut butter may be infected with fungus, which is a source of worry. The fungus grows on the peanut butter, and as a consequence, it produces aflatoxin, which is toxic.
There have also been a few isolated instances in which peanut butter has been contaminated with Salmonella or E. coli bacteria. Interestingly, a number of studies have found that the levels of bacteria and aflatoxin in old peanut butter are significantly lower.
Apparently, there is not enough moisture in peanut butter for bacteria to live, thus there are less of them in the older peanut butter, which supports this idea.
The Shelf Life of Peanut Butter
Natural peanut butter, according to the USDA and the National Peanut Board, will last for a few months in the cupboard…
Peanut butter with additional stabilizers has a longer shelf life than plain peanut butter: 6-9 months unopened in the cupboard and 2-3 months once opened. Keeping open jars of peanut butter in the refrigerator will extend their shelf life by several months.
However, there have been several reports of peanut butter staying even longer than this. Many people have reported that peanut butter that was more than 5 years old still tasted good.

Is it possible for peanut butter to go bad?
In terms of fat and protein, peanut butter is quite rich in both, yet it has very little moisture. Because of the low moisture content, bacteria and fungus have a tough time growing in it.
The occurrence of peanut butter going bad in the sense that it would make you sick to your stomach is quite rare. Peanut butter’s fats, on the other hand, oxidize and become rancid with time.
As a result of this, the peanut butter will have an unpleasant sour or bitter taste. The expiry date — also known as the best-by date — of most packaged peanut butters is displayed on the container, and it indicates how long the product will remain fresh.
These labels, on the other hand, are not required and do not guarantee the safety of the product. This implies that your peanut butter may still be OK to consume after it has passed its best-before date.
A quick reminder that sight and smell are the most reliable methods to determine whether your peanut butter has gone rancid.
When compared to fresh peanut butter, which is naturally creamy and smooth, poor peanut butter may have a hard and dry feel. As opposed to its regular light tan tone, it might look dark brown when compared to other colors.
Additionally, if the fragrance becomes more harsh, soapy, or bitter, it is likely that the food has been spoiled. Furthermore, if your peanut butter has a little sour flavor rather than a nutty flavor, it may have gone bad as well.

Always keep in mind that oil separation is usual for natural peanut butters, which may be due to the lack of stabilizer additives.
It’s not an indication that the peanut butter has gone bad, as some people believe. Changes in scent, texture, and taste are all symptoms that powdered peanut butter has become stale or spoiled.
Powdered peanut butter is a simple ingredient to work within the kitchen
PB2 is a convenient and quick method to add peanut flavor to a variety of meals. It may be used directly in powdered form, or it can be rehydrated with water to produce a paste, depending on your preference.
The fact that the powder has very little fat means that it will blend more easily with liquids than typical nut butters. Unlike conventional peanut butter, it may also be used as a dry condiment, which makes it a versatile ingredient.
When PB2 is used as a powder, it can be used to make the following things:
After being rehydrated into a paste, PB2 may be consumed as a dip or used to make handmade delights by mixing it with other ingredients.
PB2 paste, on the other hand, lacks the creamy texture and rich feeling of peanut butter and is frequently characterized as gritty or slightly bitter.

How Do I Store Regular Peanut Butter for a Long Period of Time?
Regular peanut butter may be kept in the refrigerator for a longer period of time than powdered peanut butter. If you follow these recommendations, it should last around 2 years (thank me later).
|1. Maintain Your Cool
Temperature has the greatest effect on the rate at which peanut butter goes rancid of all the elements that contribute to this. Even a minor rise in temperature has the potential to accelerate the rate at which PNB degrades. Make an effort to store the peanut butter in a cool, dark area and avoid allowing it to warm up over room temperature. Though it is possible that the stench would attract rats, a root cellar is a decent alternative…
Is It Necessary to Freeze Peanut Butter?
Keeping peanut butter in the freezer will help to prevent it from becoming rancid over time. PNB has the ability to last an indefinite amount of time in the freezer. However, I do not advocate freezing your peanut butter at this time. Your freezer space would be better utilized for perishable items or expensive commodities such as long-term coffee preservation, which is the primary rationale for this practice. Over time, the scents from the freezer would be absorbed by your PNB as well.
2. Keep away from direct sunlight
The oxidation process is accelerated by ultraviolet radiation. Keep peanut butter in a cool, dark area to keep it fresh for extended periods of time. Alternatively, you may place the peanut butter jars in paper bags to keep them protected from the sun.
3. Store peanut butter in glass jars to keep it fresh
When it comes to packaging for long-term peanut butter storage, glass jars outperform plastic containers hands down. Because they prevent as much oxygen from entering the PNB, it will persist for a longer period of time. Despite their appearance, plastic containers do not seal fully against the elements. Tiny pores in the plastic allow air and moisture to pass through, allowing the plastic to breathe. Peanut butter stored in plastic containers will retain more moisture in humid locations, increasing the likelihood of germs growing in the product. If you must purchase PNB in plastic containers (it is less expensive than glass and will not shatter), choose PET plastics rather than PP plastics. Another nice choice is peanut butter in metallic pouches, which is available at most grocery stores.
It has come to my attention that not everyone who would otherwise enjoy eating one-ingredient peanut butter (salt- and sugar-free, "natural" (sigh)) has cracked the code of how to tame it into usability. And no, "store upside down and stir before using" will not cut it. Let's go! pic.twitter.com/olvZs9MKDa

1. What is the shelf life of peanut butter?
Peanut butter has a rather lengthy shelf life in most cases. Commercial peanut butters will keep in the pantry for 6–24 months if they are not opened, and 2–3 months if they are. Natural peanut butters do not include preservatives and may be stored for several months if not opened, or for up to one month if opened.
2. What is the shelf life of homemade peanut butter when kept in the refrigerator?
Because homemade peanut butter is made entirely of peanuts, it may be stored in the refrigerator for up to 3 months if stored in an airtight container. The scent of rotten peanut butter will alert you that the peanut butter has gone bad (believe me, you’ll know if it’s gone bad!)
3. What is the proper temperature for storing peanut butter?
Peanut Butter should be served at room temperature. Generally speaking, storing Peanut Butter at room temperature is a good option since the content of the peanut butter is not influenced by the temperature. Peanut butters have a shelf life of around 9 months in most cases.
4. What is the reason for the absence of the requirement to refrigerate peanut butter?
This type of peanut butter, which is sometimes referred to as “natural,” is made only of pulverized peanuts and has no other ingredients. Refrigeration is recommended since oils can grow rancid and ruined if left out at room temperature for an extended period of time.

So, what did we learn in class today? We now know that if properly stored, an open jar of peanut butter may last up to three months.
It is recommended that you keep your peanut butter refrigerated (where it can maintain its quality for another 3-4 months). If the container is not chilled, oil separation may occur. Eating outdated peanut butter, even if it’s been a few years, is usually regarded safe.
Even though the peanut butter has gone rancid and has a bad taste, it will not give you food poisoning if you eat it correctly. However, some people may get stomach pain as a result of eating spoiled food.
Furthermore, rancid peanut butter has less nutrients than fresh peanut butter. It’s likely that peanut butter is fungus-infected, which is a cause for concern.
As the fungus develops on the peanut butter, it creates aflatoxin, which is a dangerous substance. Peanut butter has also been shown to be contaminated with Salmonella or E. coli germs in a few rare cases.
Interestingly, a lot of studies have discovered that aged peanut butter has considerably lower amounts of bacteria and aflatoxin. Enjoy the rest of your day, always stay safe, and treat others with kindness and respect!
