What Happens If You Dont Refrigerate Peanut Butter?
If you don’t refrigerate peanut butter, it will stay safe to eat for a couple of weeks at room temperature, but it may start to go rancid and spoil after that. The oils in peanut butter can become rancid over time, which can give it an unpleasant taste, smell, and texture. Refrigerating peanut butter will help keep it fresher for longer and prevent it from spoiling.
