To preserve food, you need to stop bacteria or fungus from growing.
Most bacteria and fungus need one or all of the following to grow.
nutrient
moisture
temperature
To preserve food, you can take away the moisture by adding chemicals that will absorb the moisture, like salt and sugar.
And many times, you also sun dry it also to take away additional moisture.
