To make food last longer in storage.
Additives are put into food to make it taste better, look better and last longer. Sometimes, substances are merely applied topically. For example, ethylene gas is used to change the color of green oranges to orange, and carbon monoxide is used to restore or preserve cut meat's bright red color. Even at home, we put additives into our food, for the same reasons. Salt, sugar and vinegar can be used to help preserve food.
There isn't a way to make food last forever. However, you can extend the shelf life of certain things. For example, meats, fruits, veggies and breads can last a while longer if you freeze them.
The pickling process is used to preserve food. Usually vinegar is used, which is an acid (acetic acid). The rotting process involves bacteria. An acid solution kills most bacteria, so stops or slows down the rotting process.
