Peanut butter, that irresistible spread, can transport you back to your childhood with just one bite. Its slightly salty flavor, paired with sweet and tart jam or jelly, was a childhood staple. The good news? Peanut butter is also beneficial for your health. However, while some enthusiastic peanut butter lovers might finish an entire jar in a week, most consumers take a few months to reach the bottom.
This presents a dilemma: how long does peanut butter actually last? Contrary to its seemingly eternal shelf life, peanut butter often expires within a few months after opening, or even sooner. Here are some indicators to determine if your creamy or crunchy nut butter has gone bad: smell, taste, and appearance. A sealed jar of peanut butter with preservatives can last for six months to two years in the pantry, but an opened jar, exposed to oxygen and microorganisms, only lasts two to three months. Unopened natural peanut butter lasts a maximum of six months at room temperature, and once opened, it begins to go bad after just a month. The telltale signs of spoiled peanut butter include a rancid, bitter, or overly pungent taste. Natural peanut butter stored at 50°F (10°C) showed signs of oxidative stability loss after 12 weeks, while at higher temperatures (77°F and 95°F or 25°C and 35°C), it lasted only four weeks. Aside from the unpleasant taste, spoiled peanut butter emits a foul odor. If you detect a bitter, metallic, or soap-like scent, it's time to discard it. Darkening color, dry texture, or the presence of mold are also clear indicators of spoilage. Remember, natural oil separation is normal and a sign of good-quality nut butter.Always check the expiration date as a starting point. Refrigerating peanut butter once opened can extend its shelf life. Store it in a dry, cool environment to maintain freshness. To prevent separation between solids and oils, flip the jar upside down when storing, or simply agitate the separated liquids with a spoon or spatula. You can also soften cold peanut butter quickly by leaving it at room temperature for 10 to 15 minutes. If you regularly consume peanut butter and want to minimize food waste, freezing it is an excellent option for long-term storage. To avoid repeatedly defrosting the entire jar, consider these two hacks: freeze peanut butter in ice cube trays for single-portion convenience, or spread thin layers on parchment paper for easy, ready-to-use portions. These methods ensure you always have fresh peanut butter on hand, ready for your next delicious treat or baking project
