How Does Vinegar Preserve Food?

Answer

The vinegar that is added to food preserves the food because it is an acid. the acid in the vinegar helps the food not grow bacteria that will make the food rot. If vinegar is not added, the food will rot at a faster pace and can't be eaten after a day or two. There are other preservatives used in conjunction with vinegar to help food stay on shelves longer. Some other additives are salt, brine, and alcohol.
