Why is drying food a good way to preserve food?

Answer 1

As we can see from the massive search for water on Mars, water is necessary for life to exist. Without water, there cannot be life as we know it. When food is dried, the water in it is removed. This makes it impossible for bacteria, yeast and molds - the living things that make food 'spoil' - to survive and multiply. Drying food is probably the first way that humankind started preserving food. We began by using grains like wheat that dried naturally before being harvested and progressed to the wonderful dried fruits, beans, vegetables, meats and fish that we now enjoy.

Answer 2

Dehydrated food has been proven to work through the ages. It preserves everything that has water content. For example, while it would take 2 weeks max for a fruit to spoil, it would take over a year for the same fruit to spoil if it were dried.

Answer 3

Food spoils because bacteria grow. When you remove the water ( by way of dehydration ) spoilage is hindered. Keep in mind, dehydrated foods CAN go bad, if not handled properly.

Answer 4

It lasts longer if you dry it. Also, some people thing dried food tastes better that non dried.

Answer 5

Food dehydrates because it has water in it that can be removed by heat or sunlight.

Answer 6

Because, too often, bacteria dwell in wet areas - like the moisture in foods - so drying can help prolong its edibility.
