WINE ADDITIVES
Most foods sold in the developed world contain substances added for a desired beneficial purpose. In the case of food preservation, many compounds are added to foods that curtail the process of oxidation and kill pathogens. With respect to winemaking, additives are used although not for the exact same reasons. It is important to remember that oxidation is always a problem with winemaking. Pathogens however do not present a problem due to the makeup of wine itself. The presence of alcohol as well as the acidic nature of wine presents an environment where pathogens cannot survive.
