GRAS is an acronym formed from the first letter of each word in 'Generally Recognized As Safe.' The term was introduced by the U.S. Food and Drug Administration in the 1958 Food Additives Amendment to the Federal Food, Drug, and Cosmetic Act. It created a category of substances that food manufacturers could use without pre-market approval, as long as the safety of the substance was widely accepted by qualified experts.
