wow lnguyen, you're a diamond member!, probably 90% of your posts are on ramen..
anyways, ramen noodle is just wheat! you dont need much perservatives to perserve dried wheat! if you look at the list of ingredients, the major ones are wheat, salt, and oil. the noodle is the wheat and seasoning is the rest,
let's put it into perspective, EVERY single food we eat contains perservatives (well except for fresh stuff, but who eat those anymore!), for example cereal, milk, ice cream, HECK THERE'S MORE PERSERVATIVES IN GENERIC ICE CREAM AND FROZEN TV FOOD THAN A DOZEN SERVINGS OF RAMEN NOODLES!
