**Peanut Butter Shelf Life**

1How Long Does Peanut Butter Last?

– Homemade peanut butter usually has a minimum shelf life of six months, while unopened commercial peanut butter has a two-year shelf life. Once opened, commercial peanut butter can last at least six months.

– It is recommended to consume peanut butter within the time frame suggested by the manufacturer. Even if it is past its expiration date, the flavor of the butter may not change, but the quality will deteriorate, and it won’t taste as good as fresh peanut butter.

– Peanut butter can go bad before the expiration date listed on the package if it becomes “contaminated” with bacteria from the external environment or is not stored properly.

2Signs of Spoiled Peanut Butter

– Peanut butter has gone bad when it emits an unusual odor and has a different taste and color compared to when it was first purchased.

– It is normal for peanut butter to separate over time, with a layer of oil forming on the surface. Simply stir the oil back into the butter with a clean spoon; this does not indicate that the butter has gone bad.

– Another thing to note is that if the peanut butter doesn’t taste as good as it used to, it doesn’t necessarily mean it has gone bad unless it exhibits other signs of spoilage, such as an unusual odor, taste, or color.

– When peanut butter has gone bad, it is best to discard it for your health, even if the jar is still mostly full.

3How to Store Peanut Butter Properly

– Peanut butter is high in fat and low in water content, which makes it difficult for bacteria and mold to grow. However, it can go rancid due to oxidation, especially if it is exposed to air.

– Store peanut butter in a jar with a tight-fitting lid, and make sure to close the lid securely after each use.

– Commercial peanut butter should be stored in a cool, dark place, while homemade peanut butter should be refrigerated.

– Once opened, commercial peanut butter should be tightly closed and stored in a cool, dark place. After a few months, it is recommended to refrigerate it to preserve the flavor and slow down oil separation.

Frequently asked questions

Unopened peanut butter can last up to a year past the best-by date, while opened peanut butter will stay fresh for about 3-4 months. Natural peanut butter with no added sugars or preservatives may only last a few months, even when unopened.

Peanut butter that has gone rancid will have an unpleasant, bitter smell and taste. It may also have mold growth, indicated by discolored spots or fuzzy patches. If the oil has separated and formed a thick layer at the top, it does not necessarily mean the peanut butter has gone bad – simply stir it back in.

Refrigeration is not necessary for unopened peanut butter, but it can extend the shelf life by a few months. Once opened, it is recommended to refrigerate natural peanut butter, as it is more prone to spoilage. Traditional peanut butter can be stored in a cool, dry place or in the refrigerator, depending on personal preference for texture and spreadability.

In addition to rancidity and mold, another sign of spoilage is an off taste or texture. If the peanut butter tastes sour, bitter, or otherwise unpleasant, it has likely gone bad. A change in texture, such as becoming dry and crumbly or excessively oily, is also an indication that it should be discarded.

While it is unlikely to cause serious illness, consuming expired peanut butter may result in an upset stomach, diarrhea, or vomiting due to the growth of harmful bacteria or mold. It is always best to err on the side of caution and discard peanut butter that is past its recommended consumption date.
