Twinkie Shelf life 25 Days

Twinkie Shelf life 25 Days- Today I found out that Twinkies have a shelf life of only 25 days.  The popular notion that they “last forever” or for some ridiculously large amount of time is incorrect.
Here are some other popular myths concerning Twinkies:
Twinkies aren’t baked.  The sponge cake instead is made from a chemical reaction that causes a cake-like material to foam up.  It is then colored dark brown at the bottom to give the appearance of being baked.  (This is of course false.  Twinkies are in fact baked and their primary ingredients are flour, sugar, and eggs.)

Contain a chemical used in embalming fluid which helps account for some of their extreme longevity.  (wrong again!)
The Twinkie will last longer than the cellophane wrapper they’re wrapped in (nope, 25 days and then they get stale and go bad in a similar fashion to any other bread)
Here’s some actual true information about Twinkies.  Twinkies were created in 1930 as ladyfinger-shaped spongecakes.   They were first thought up by James A. Dewar, the vice president of Continental Bakeries who sold under the Hostess brand.  Dewar sought to put the machines used to make cream filled strawberry shortcake to good use when strawberrys were out of season and the machines normally sat idle.  So he got an idea to create a banana cream filled cake.  That’s right.  Originally, Twinkies were filled with banana cream, which I suppose explains why they chose to make them look as they do.
During World War II however, bananas became scarce.  Hostess then decided to switch to vanilla cream.  This ended up being much more popular than the banana filled version; so when bananas became readily available again, they chose not to switch back.
The name “Twinkie” was also thought up by James Dewar.  On the way to a marketing meeting, he saw a billboard advertising “Twinkle-Toes Shoes”, and thought up the name “Twinkies”.
When Twinkies first came out, they not only were banana filled, but they also had an incredibly low shelf life.  This was due primarily to the dairy products contained in Twinkies giving them only a two day shelf life on average.  This obviously cut into the profit margins.
With the need for longer shelf life, they started substituting ingredients in the original recipe with artificial ingredients.   Among those are cellulose gum, which gives Twinkie cream its smooth feel.  Another place you can find this cellulose gum is in rocket fuel.
But that’s not the only fuel based ingredient in a Twinkie.  The chemicals that make up the artificial butter flavor are themselves derived from petroleum.
Another interesting ingredient is corn dextrin.  This gives Twinkies their sticky crust.  Another place you can find this wonderful ingredient is in various glues;  for instance, the glue that you find on the back of envelopes.
Interestingly though, of the 39 ingredients that make up a Twinkie, only one of them is strictly a preservative or rather its only purpose in being included is because it’s a preservative.  Some of the other chemicals have preserving side effects, but their use is primarily as substitutes for the dairy ingredients.  The lack of these dairy ingredients and the air tight plastic wrap are the primary reason that the Twinkie can last the 25 days on the shelves and can out last so many of its other baked brethren in that respect.
Despite their slightly unhealthy nature (150 calories each; with quite a dose of fat included), Hostess now churns out more than 1000 Twinkies per minute or about 500 million per year.  The cakes are each baked for 12 minutes; injected with cream; flipped over so the round bottom is now the top; then packaged for shipping.
Bonus fun fact:  According to Hostess, it takes about 45 seconds to explode a Twinkie in a standard powered microwave.  Try this at home kids…  Seriously, anybody want to try this and report back on the results?
