Food Preservation

Principle: Food can be preserved well by proper processing without using artificial preservative to avoid food corruption. There are many examples: wine, bacon, cheese, and pickle can be kept for quite a long time; dry food is made to preserve food longer by dehydrating. Try to experiment if you can find similar methods to preserve food. Usually, using vinegar, wine like champage, soy source, or chili peppers is helpful to preserve food.
