We have guidance documents available on the FDA's website, including <a data-entity-substitution="canonical" data-entity-type="node" data-entity-uuid="5aaf117d-c91e-4810-b953-8dd69b4d2132" href="/regulatory-information/search-fda-guidance-documents/guidance-industry-pre-petition-consultations-food-additives-and-color-additives" title="Guidance for Industry: Pre-Petition Consultations for Food Additives and Color Additives">Guidance for Industry: Pre-Petition Consultations for Food Additives and Color Additives</a>, that assist manufacturers with submitting a petition.</p> <p>The FDA <a data-entity-substitution="canonical" data-entity-type="node" data-entity-uuid="7f26c75f-bbcb-4d71-b5bf-edca6c51b104" href="/regulatory-information/search-fda-guidance-documents/guidance-industry-questions-and-answers-about-food-additive-or-color-additive-petition-process" title="Guidance for Industry: Questions and Answers About the Food Additive or Color Additive Petition Process">publishes a notice of the petitions</a> under FDA review in the public <a href="https://www.federalregister.gov/">Federal Register</a>. The FDA evaluates the petition, and other available data and information to determine if the data demonstrate that the food additive is safe under the proposed conditions of use. The safety of food additives must be supported by science that demonstrates its use meets the FDA’s safety standard – a reasonable certainty of no harm.</p> <p>When evaluating the safety of an ingredient submitted in a food additive petition, the FDA considers:</p> <ul> <li>What is the food ingredient?</li> <li>How will the food ingredient be made?</li> <li>How much of the ingredient will be in food?</li> <li>What types of foods will the ingredient be used in?</li> <li>How much of the food ingredient will consumers eat?</li> <li>How does the body metabolize the food ingredient (including absorption, digestion, metabolism, and excretion)?</li> <li>What are the results of relevant scientific studies on the safety of the ingredient?</li> </ul> <p>The FDA determines an Acceptable Daily Intake or the amount of a substance considered safe to consume each day over the course of a person’s lifetime. This level includes built in a safety margin that includes factors accounting for potential uncertainties in the data and known variability within the population and vulnerable populations, such as people who are pregnant and children. We also consider expected exposure for consumers who eat the average amount of foods containing the food additive and for consumers who eat much more than the average amount of foods containing the food additive. These approaches ensure that the consumption of an additive from an approved use is much lower than what would be expected to have any adverse effect.</p> <p>For every food additive the FDA approves, the agency issues a regulation that authorizes uses of the food additive that meet the safety standard for food use. The food additive regulations are in the U.S. Code of Federal Regulations (CFR). These regulations may specify the types of foods in which the food additive can be used, the maximum amounts to be used in those foods, and how it should be identified on food labels. Manufacturers are also required to limit the amount of food additives to the amount necessary to achieve the desired effect.</p> <p>The FDA manages and maintains a <a href="https://www.cfsanappsexternal.fda.gov/scripts/fdcc/?set=FAP-CAP">public inventory</a> where we list all of the food additive petitions under active FDA review or that are filed but not active because deficiencies were identified during the FDA’s review.</p> <h2><a id="GRAS" name="GRAS">Ingredients that are Generally Recognized as Safe (GRAS)</a></h2> <p>The definition of food additive in the <a data-entity-substitution="canonical" data-entity-type="node" data-entity-uuid="559edc18-553a-4bfb-bb73-0bf1ad6c37d3" href="/regulatory-information/laws-enforced-fda/federal-food-drug-and-cosmetic-act-fdc-act" title="Federal Food, Drug, and Cosmetic Act (FD&C Act)">Federal Food, Drug, and Cosmetic Act</a> includes a provision for the uses of ingredients that are <a data-entity-substitution="canonical" data-entity-type="node" data-entity-uuid="55866612-9996-491e-8467-e79f4572e7e6" href="/food/food-ingredients-packaging/generally-recognized-safe-gras" title="Generally Recognized as Safe (GRAS)">Generally Recognized as Safe (GRAS)</a>. As such, these ingredients do not require pre-market review by the FDA. For the use of an ingredient to be considered GRAS, all data necessary to establish safety must be publicly available and its safe use must be generally recognized by qualified experts. In addition, GRAS uses must meet the same safety standard as for food additives, a reasonable certainty of no harm under the conditions of its intended use and have the same quantity and quality of information that would support the safety of a food additive. Some examples of GRAS ingredients include canola oil, vinegar, and spices such as black pepper.</p> <p>Any person, typically a food or ingredient manufacturer, that has concluded that the use of an ingredient can meet the standard for GRAS may notify the FDA through the <a data-entity-substitution="canonical" data-entity-type="node" data-entity-uuid="cb028c9c-985c-41ec-b489-ea146068477e" href="/food/generally-recognized-safe-gras/about-gras-notification-program" title="About the GRAS Notification Program">FDA’s GRAS Notification Program</a>. The FDA has established a <a data-entity-substitution="canonical" data-entity-type="node" data-entity-uuid="320399c6-057f-4bdd-a638-22054474a7c8" href="/food/generally-recognized-safe-gras/how-us-fdas-gras-notification-program-works" title="How U.S. FDA's GRAS Notification Program Works">GRAS Notification Program</a> to help ensure that these ingredients are safe for the ways in which they will be used and to help industry meet its responsibility for ensuring the GRAS status of ingredients they intend to use in food. This notification is not mandatory; however, the FDA strongly encourages manufacturers to contact the agency and follow the available procedures for our oversight of GRAS conclusions by submitting a GRAS notice. The FDA also assists the food industry through our regulations and <a data-entity-substitution="canonical" data-entity-type="node" data-entity-uuid="55866612-9996-491e-8467-e79f4572e7e6" href="/food/food-ingredients-packaging/generally-recognized-safe-gras" title="Generally Recognized as Safe (GRAS)">guidance documents</a>.</p> <p>When the FDA evaluates a GRAS Notice, the agency considers whether the notice demonstrates that the ingredient is safe under the conditions of its intended use and whether the criteria for general recognition are satisfied. When evaluating the use of a GRAS ingredient, the FDA considers all relevant and reliable information to understand:</p> <ul> <li>What is the food ingredient?</li> <li>How will the food ingredient be made?</li> <li>How much of the ingredient will be in food?</li> <li>What types of foods will the ingredient be used in?</li> <li>How much of the food ingredient will consumers eat?</li> <li>How does the body metabolize the food ingredient (including absorption, digestion, metabolism, and excretion)?</li> <li>What are the results of relevant scientific studies on the safety of the ingredient?</li> </ul> <p>The FDA consults with U.S. Department of Agriculture during the review process for GRAS notices for ingredients that are proposed for use in meat and poultry products.</p> <p>Following this evaluation, the FDA responds to the manufacturer with a letter describing whether we question the basis for the manufacturer’s GRAS conclusion. The FDA manages and maintains a <a data-entity-substitution="canonical" data-entity-type="node" data-entity-uuid="422e99ab-a179-419f-a71b-c96b1c56b8e6" href="/food/generally-recognized-safe-gras/gras-notice-inventory" title="GRAS Notice Inventory">public inventory</a> where all GRAS notices that have been filed by the agency, along with the supporting data, and FDA’s final response letters to manufacturers are available to the public. Manufacturers that choose not to go through the FDA’s GRAS Notification program are still responsible to produce products that are compliant with the law.</p> <h2>Post-market Assessment Related to Food Ingredients</h2> <p>The FDA stays abreast of the latest science available about food additives and GRAS ingredients in a variety of ways. We participate in international scientific and standard setting activities related to food ingredient safety such as the <a data-entity-substitution="canonical" data-entity-type="node" data-entity-uuid="601c9c5a-5753-4917-bfe0-e4a939b55c79" href="/food/international-cooperation-food-safety/fdas-participation-codex" title="FDA's Participation in Codex">Codex Alimentarius Commission</a> and the <a href="https://www.who.int/groups/joint-fao-who-expert-committee-on-food-additives-(jecfa)/about#:~:text=The%20Joint%20FAO%2FWHO%20Expert,World%20Health%20Organization%20(WHO).">Joint FAO/WHO Expert Committee on Food Additives</a>, attend scientific conferences, and engage other public health and research stakeholders. These activities help us stay informed about the safety and exposure of food additives in scientific literature and released by other agencies.</p> <p>FDA scientists also assess the science about the exposure and safety of a food ingredient each time we file a food additive petition or review a GRAS notice. Additionally, we may proactively choose to assess a food additive or GRAS ingredient in food when new information about its safety profile warrants assessment. The FDA has strict data requirements that must be met to establish safe conditions of use during review of a pre-market submission, and as new scientific information becomes available, we may re-evaluate the safety assessments. This includes reviewing published scientific literature and studies from other regulatory and health agencies in the U.S. and in other countries, and updated information when the same substance is the subject of a new submission. In some of our assessments, we identify areas where additional information is needed. We may work with research partners on studies to help fill these data gaps. We are <a href="/food/food-ingredients-packaging/food-chemical-safety#EnhancedApproach">exploring how to obtain better information</a> on the post-market use of food ingredients from industry and other stakeholders.</p> <p>If after the FDA’s assessment of a food additive or GRAS ingredient we have determined its use meets our safety standard, the regulatory status of the food additive or GRAS ingredient would remain unchanged. If after the FDA’s assessment of a food additive or GRAS ingredient, we have determined its use does not meet our safety standard, the agency can take various actions to protect public health. These actions include issuing a public <a data-entity-substitution="canonical" data-entity-type="node" data-entity-uuid="62fae505-06da-4e40-980c-835788ea4ecd" href="/inspections-compliance-enforcement-and-criminal-investigations/compliance-actions-and-activities/warning-letters" title="Warning Letters">warning letter</a> to companies that manufacture or distribute the food ingredient and/or food containing the food ingredient, issuing a public alert, and taking enforcement action to stop distribution of the food ingredient and foods containing it on the grounds that such foods are or contain an unapproved food additive. Some changes can take time such as revoking a food additive approval because we are required to follow certain regulatory processes, such as providing an opportunity for public comment. Some recent examples include the agency’s work to remove <em>trans</em> fat and warn companies marketing Cannabidiol (CBD) and Delta-8 THC products:</p> <ul> <li><a
