Yes, ketchup does have a standard of identity set by the U.S. Food and Drug Administration (FDA). According to the FDA’s regulations, ketchup must contain specific ingredients and meet certain criteria to be labeled as “ketchup.” The standard of identity for ketchup includes requirements such as the use of tomatoes, vinegar, sweeteners, and spices, as well as limitations on the amount of certain ingredients like salt and preservatives. This standard helps ensure that products labeled as ketchup meet certain quality and composition standards.
