how long does peanut butter last? Does it go bad or does it last for a long time? People often wonder if peanut butter goes bad after opening the jar. This article tells you how long peanut butter usually stays good, how to tell if it's gone bad, and how to store it properly. Peanut butter is a popular spread because it tastes good and feels smooth. It's also a great source of vitamins, minerals, and healthy fats, all of which are important for health. Peanut butter usually lasts a long time compared to other spreads. This is because peanut butter is high in fat and has a low amount of moisture, which makes it hard for bacteria to grow. There are other important things that can change how long peanut butter will last. First of all, how it's made has a big impact on how long it will last. 
Most commercial peanut butter use stabilizers like hydrogenated vegetable oils or palm oils and preservatives like sodium benzoate to make them last longer. Stabilizers keep the oil from separating and make the texture and appearance better. Preservatives, such as sodium benzoate, stop the growth of microorganisms. Because stabilizers and preservatives are added, commercial peanut butter can stay in the pantry for 6–24 months if it hasn't been opened, or for 2–3 months if it has. Putting it in the refrigerator can make it last longer than this. On the other hand, peanut butter that says it is natural must have at least 90% peanuts in it. Most of the time, they don't have stabilizers or preservatives, so they don't last as long. But some natural peanut butter might have stabilizers in it to keep the oil from separating. Natural peanut butter without stabilizers can usually be kept in the pantry for a few months or up to a month once it has been opened. 
But they may last up to a year in the fridge if they aren't opened, or 3–4 months if they are. Many natural jars of peanut butter that only have peanuts and salt in them say "refrigerate after opening" to keep them from going bad. Because different brands add different things, the shelf life of natural peanut butter can vary a lot. It's important to check the "best by" date on the packaging. Powdered peanut butter is a new alternative that is made by pressing most of the natural oils out of roasted peanuts and then grinding the nuts into a powder. Most labels say they will last 10–12 months if they aren't opened and 4–6 months if they are. But powdered peanut butter may last longer than the date on the label if it is kept unopened and in a cool, dry, dark place, like the pantry. This is because it has less fat than regular peanut butter, so it doesn't react with oxygen as much. How To Know If Something Is Bad: Most peanut butter jars that come in a package have best-by dates or expiration dates printed on the container. These dates show how long the product will stay fresh. But these labels aren't required, and they don't make sure that the product is safe. This implies that you can continue eating the peanut butter even after the date, has passed. If your peanut butter has gone bad, you can tell by how it looks and how it smells. 
Peanut butter's texture should be smooth and creamy when it's first made, but it can become hard and dry if it goes bad. It could also look dark brown instead of the usual light tan color. Also, it has probably gone bad if it smells more sharp, soapy, or bitter. Also, if your peanut butter tastes a little bit sour instead of nutty, it may be bad. Keep in mind that natural peanut butter often separates because they don't have enough stabilizers. It doesn't mean the peanut butter is spoiled. Powdered peanut butter can be harder to tell if it has gone bad, but changes in the way it smells, feels, and tastes are good signs. How To Keep Peanut Butter Fresh: It's important to store peanut butter the right way if you want it to last longer. Even though it doesn't need to be kept in the fridge, keeping it cold makes it last longer. If you don't want to put peanut butter in the fridge, try to keep it in a cool, dark place, like the pantry. Also, you should always close the peanut butter jar tightly. 
If you leave peanut butter out in the air for too long, it may go bad faster. Also, when you use peanut butter, make sure to use clean tools. Used or dirty utensils could spread bacteria that you don't want, which can make food go bad faster. Additionally, powdered peanut butter needs to be kept in a location that is cold, dry, and dark, such as the pantry. Creamy peanut butter made from powder can be refrigerated for up to 48 hours if the container is sealed firmly after preparation. Peanut butter stays good for a long time. Commercial peanut butter can stay in the pantry for 6–24 months if they haven't been opened, or 2–3 months if they have. Natural peanut butter doesn't have any preservatives, so it can last for months if they aren't opened and up to a month if they are. But some brands of natural peanut butter with stabilizers may last longer, so it's important to check the "best by" date. 
Powdered peanut butter should be kept in a cool, dark, and dry place, like a pantry. The best-by date says that it can be kept for up to a year. But since it has qualities that make it less likely to go bad, it may last longer than this. Any kind of peanut butter can last much longer if it is used and stored correctly and kept in the fridge. A change in the texture of the peanut butter, where it becomes dry and hard, changes in the scent, including a lack of aroma, and a flavor that is more sour or bitter are all indications that the peanut butter has gone bad.
