Want to keep snack foods like potato chips, crackers and tortilla chips fresh for months after you’ve opened the bag or box? Store them in your freezer. The biggest culprit in making snack foods go stale is moisture. Storing them in the freezer keeps them away from humidity and freezes them fresh. Since there’s a very tiny amount of water in snack foods, the slight freeze actually prevents the starches from retrograding. And when you remove them from the freezer, it only takes a few seconds for your snacks to defrost.
