Recently, the U.S. Food and Drug Administration(FDA)Website reports，The FDA is in the process of revising its food additives regulations，A total of 7 synthetic fragrances and flavor enhancers are no longer allowed(Adjuvants) ，In response to two food additive petitions from the community。
One of the petitions was filed by the Breast Cancer Fund，Center for Environmental Health，Center for Food Safety，Center for Science in the Public Interest，Consumers' Union，Environmental Protection Fund，Environmental Working Group，Improving the environment for children，Natural Resources Defense Council、We submitted to the FDA for the Environmental Justice Action Coalition and Mr. James Huff, among others，The data in the petition shows:，Under test conditions，There are 6 synthetic fragrances that can cause cancer in experimental animals。
这6种合成香料分别是合成的二苯甲酮（benzophenone）、Ethyl acrylate、Methyl eugenol、Myrcene、Pulegone and pyridine。According to Federal Food、Drugs and Cosmetic Act(FD&Section 409 of Bill C(c)(3)strip)Delaney Terms，These substances will be removed from the list of food additives。1958This provision requires the FDA not to approve the use of any food additive that has been found to induce cancer in humans or animals at any dose。
While the FDA is in the process of amending food additive regulations under the Delaney clause，But the FDA's rigorous scientific analysis has been established，In normal use，These synthetic fragrances do not pose a risk to public health。These synthetic flavors are widely used in food products marketed in the United States，The dosage is very small，Exposure is very low，The risk is also low。
While the FDA's exposure assessment of these substances does not indicate that they pose a risk to public health under the conditions of intended use，But the petitioner provided evidence，It has been shown that these substances cause cancer in animals exposed to much higher doses。therefore，The U.S. Food and Drug Administration withdrew the listing of the six synthetic flavors only on legal grounds。The FDA considers these substances otherwise safe。
Each of these synthetic substances has a natural counterpart in food or in the natural substances used to flavor food。FDA's removal of these synthetic flavors does not affect the legal status of foods containing natural flavors，It also does not affect the legal status of flavoring substances extracted from these foods，These are often labeled as "natural flavors".。
According to the evidence provided by the petitioner，That is, benzophenone causes cancer in animals，The FDA is also in the process of revising food additive regulations，It is no longer allowed to be used as a plasticizer in reused rubber products that come into contact with food。
For these 6 synthetic fragrance substances，FDA will publish the rule in the Federal Register，A 24-month transition period is provided，So that businesses can identify suitable alternative ingredients and reformulate their food products。
Other than that，In response to a petition for food additives from the Thuroxylenene Research Center，FDA will revise its food additives regulations，The use of styrene as a synthetic fragrance and adjuvant is no longer permitted，Because the industry no longer uses this synthetic fragrance。
