Have you heard the one about how stores are still selling the original stock of Twinkies, made in 1930? Or how they're injected with embalming fluid? When the subject of "long shelf life" comes up, someone's sure to pipe up about how Twinkies and cockroaches would be the sole survivors of a nuclear attack. Fortunately (or unfortunately, depending on who you ask), it's all urban legend. It's true that Twinkies are pretty much jam-packed with totally unnatural ingredients (Polysorbate 60, anyone?), but only one of them is an actual preservative. Hostess says that the official shelf life of a Twinkie is 25 days. Not bad, but you'd probably want to stock up on something more hardy if you're preparing for the end of days.
