6种保质期超长的食品（双语）
If you cook and eat it after a decade, for instance, it may lose a bit of flavor, but unopened dried pasta is edible indefinitely.
2. Canned or Dried Beans 灌装豆或干豆
They'll be ready to cook even if they've been stashed in the corners of your pantry for years. Dried beans may need a bit more soaking after long periods of time.
3. Vinegar 醋
The high acidity acts as a natural preservative that thwarts germ growth, so it can also last indefinitely. In some varieties other than white distilled, color alterations or cloudiness may develop after time, but this doesn't affect taste or quality.
4. Salt 盐
It's essentially a stone. Just as granite won't become infested with mold and bacteria, neither will your favorite edible "rock star" condiment.
5. Vanilla 香草精
Because of its high alcohol content, it can keep indefinitely, although the flavor and aroma will be best within five years. Keep away from light and heat, but do not refrigerate, even after opening, or the extract will be damaged.
6. Worcestershire sauce 辣酱油
Like many wines, this sauce gets better with age. The flavor intensifies as the liquid evaporates. Worcestershire should last for up to ten years unopened and two to three years opened if stored in a cool, dark place.
