Freezing peanuts is the best way to store them for a long time, and it retains taste and texture. The extremely low temperature in the freezer creates an environment that prevents the growth of bacteria that can render the peanuts inedible. Besides bacterial growth, the cold could also slow rancidification. However, you might want to opt for mason jars in this case. Although they’re bulky, they can protect the peanuts from being crushed by heavier items. Then when you’re defrosting them, let the peanuts thaw to room temperature before opening the container since cold nuts could absorb moisture from the air.
