Before foods can be placed on the market, they must be approved by scientists at the department of Food and Drug Administration (FDA). When a foreign substance is found in food, FDA scientists perform experiments to find out its identity. On rare occasions, corrosive agents have been found in foods. Corrosive agents have the ability to break down or destroy some substances. Bases, which are basic on the pH scale, can be corrosive.
