An acidic substance used as food additives that act as control agents to alter food ph levels in beverages and sweets or to serve as levening agents for breads. Phosphoric acid is an example of an Acidulant that is added to cola beverages to provide a tart and acidic flavor. Naturally produced organic acids such as citric acid taken from lemons and limes are also commonly added as Acidulants to flavor various foods. Tomato products use citric acid to keep canned tomatoes firmer in texture as well as reducing the pH level to assist with the sterilization process when canning.
