Answer:-)
Preservatives are natural or man-made chemicals that are added to foods to stop them from spoiling. We actually 'preserve' fresh foods ourselves every day, by storing foods in the fridge or freezer. Smoking fish or meats over burning wood or coal are also methods of preservation. Many packaged foods we buy need a preserving agent to keep them from going 'off' and to protect us against food-borne illnesses (food poisoning), which is why these preservatives are used.
