  • Reregistration Eligibility Decision (RED) for Inorganic Sulfites
    Reregistration Eligibility Decision – Inorganic Sulfites May 2007 Reregistration Eligibility Decision Inorganic Sulfites Special Review and Reregistration Division Office of Pesticide Programs U.S. Environmental Protection Agency 1801 South Bell Street Arlington, VA 22202 Introduction The Environmental Protection Agency (EPA) has completed its Reregistration Eligibility Decision (RED) for the inorganic sulfites case, which includes the chemicals sulfur dioxide and sodium metabisulfite. This assessment provides information to support the issuance of a Reregistration Eligibility Decision for inorganic sulfites. EPA’s pesticide reregistration process provides for the review of older pesticides (those initially registered prior to November 1984) under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) to ensure that they meet current scientific and regulatory standards. In this document, EPA presents the results of its review of the potential human health effects of dietary, drinking water and occupational/bystander exposure to inorganic sulfites, as well as its ecological risk findings. Evaluations performed by the World Health Organization (WHO), the International Agency for Research on Cancer (IARC), and the Agency for Toxic Substances and Disease Registry (ATSDR) were relied upon for this assessment, in addition to peer-reviewed evaluations performed by the Cosmetic Ingredient Review (CIR), the Organization for Economic Cooperation and Development-Screening Information Data Set (OECD-SIDS) and from other open literature sources. Based on this assessment, the Agency has determined that products containing sulfur dioxide or sodium metabisulfite are eligible for reregistration provided the necessary label changes are made. As a result of this assessment, one tolerance has been reassessed. I. Use Information The inorganic sulfites reregistration case includes the chemicals sulfur dioxide (CAS No.

  • Ammonium Hydrogen Sulfite Water As an Authorized Food Additive and Establish Compositional Specifications and Use Standards for This Additive
    Amendment to the Ordinance for Enforcement of the Food Sanitation Act and the Specifications and Standards for Foods, Food Additives, Etc. The government of Japan will designate ammonium hydrogen sulfite water as an authorized food additive and establish compositional specifications and use standards for this additive. Background Japan prohibits the sale of food additives that are not designated by the Minister of Health, Labour and Welfare (hereinafter referred to as “the Minister”) under Article 12 of the Food Sanitation Act (Act No. 233 of 1947; hereinafter referred to as “the Act”). In addition, when specifications or standards for food additives are stipulated in the Specifications and Standards for Foods, Food Additives, Etc. (Public Notice of the Ministry of Health and Welfare No. 370, 1959), Japan prohibits the sale of those additives unless they meet the specifications or the standards pursuant to Article 13 of the Act. In response to a request from the Minister, the Committee on Food Additives of the Food Sanitation Council under the Pharmaceutical Affairs and Food Sanitation Council (hereinafter referred to as “the Committee”) has discussed the adequacy of the designation of ammonium hydrogen sulfite water as a food additive. The conclusion of the Committee is outlined below. Outline of conclusion The Minister should designate ammonium hydrogen sulfite water as a food additive unlikely to cause harm to human health pursuant to Article 12 of the Act and should establish compositional specifications and use standards for this additive pursuant to Article 13 of the Act (see Attachment for the details). Attachment Ammonium Hydrogen Sulfite Water 亜硫酸水素アンモニウム水 Standards for Use (draft) Permitted for use in grape juice used for wine production and grape wine only.

  • Sethness Products Company
    SETHNESS PRODUCTS COMPANY SULFITE IN SETHNESS CARAMEL COLORS Sethness Caramel Colors are 100% Caramel Color. Sethness Caramel Colors do not contain any post manufacturing "sulfiting agents" typically added to food products as oxygen scavengers. These sulfiting agents are used to enhance the stability of the final product. Sulfiting agents used for stabilization are readily determined by both digestive and non- digestive methods. Sethness Caramel Colors do not contain any stabilizing sulfites. The sulfite found in Sethness Caramel Colors comes from one of two sources: 1. When Caramel Color is tested to contain above 50 ppm of sulfite, then sulfite is used as a necessary and allowed process reactant (as defined by 21 CFR 73.85) to assist in the formation of the color bodies generated in the process of manufacturing Caramel Colors. These are Class II (E150b) and Class IV (E150d) Caramel Colors. This sulfite is incorporated into the Caramel Color as a part of the polymer chains. When a Sethness Caramel Color is analyzed for free sulfite using a non-digestive method, the result is nil. 2. When Caramel Color is tested to contain less than 50 ppm of sulfite, then t h e sulfite result is assumed to be from residual levels in the carbohydrate source. Also, the test for sulfite is such that it will not give a result that is conclusively free of sulfites. Therefore, we have set our sulfite limits to be within the limit of detection and accuracy of the test and possible residual sulfites from the carbohydrate source. These are Class I (E150a) and Class III (E150c) Caramel Colors.
