A fresh peanut can last for around 6 months to a year when stored properly, but that's only if you keep them in an airtight container and away from direct sunlight. If you're like me and love to snack on peanuts, you might be going through them so quickly that you don't have to worry about shelf life – but it's still good to know, right? After all, you don't want to be stuck with a batch of stale, rancid peanuts that are only good for the trash can.
But here's a fun fact: peanuts aren't actually a true nut – they're a legume, related to beans and lentils. This means they have a slightly different set of storage requirements than, say, almonds or walnuts. For instance, peanuts are more prone to moisture absorption, which can lead to mold growth and spoilage. Who knew being a legume could be so high-maintenance?
Now, I know what you're thinking: what about roasted peanuts? Don't they have a longer shelf life than their raw counterparts? The answer is yes – and no. Roasted peanuts can last longer than raw peanuts, but only if they're stored properly in a cool, dry place. If you expose them to heat, light, or moisture, they can become rancid just as quickly as raw peanuts.
