Additives Twelve Major Groups Definition A substance added to a food to cause a Additives desired positive change in the characteristic of a food. Added to food at any point during processing/production. USDA and FDA both regulate the use of additives. Two classifications of additives Intentional Incidental B-4.01 -- Additives 2 Classification of Additives Intentional Added on purpose Functions of Food Additives Gives foods specific characteristics or prevents spoilage. Examples – Vitamin D in milk, acetic acid in dressing Incidental Get into foods unintentionally Enter anytime during processing/production Examples -- wax in milk from wax-coated carton B-4.01 Additives 3 Two Functions Twelve Major Groups Additives legally allowed when benefits Preservatives Buffers, Acids, outweigh risks. Antioxidants Alkalies Food Colors Two functions of intentional additives are: Sequestrants Food Substitutes Maintain/improve nutritional quality.

    FIVE KEYS TO SAFER FOOD MANUAL DEPARTMENT OF FOOD SAFETY, ZOONOSES AND FOODBORNE DISEASES FIVE KEYS TO SAFER FOOD MANUAL DEPARTMENT OF FOOD SAFETY, ZOONOSES AND FOODBORNE DISEASES INTRODUCTION Food safety is a significant public health issue nsafe food has been a human health problem since history was first recorded, and many food safety Uproblems encountered today are not new. Although governments all over the world are doing their best to improve the safety of the food supply, the occurrence of foodborne disease remains a significant health issue in both developed and developing countries. It has been estimated that each year 1.8 million people die as a result of diarrhoeal diseases and most of these cases can be attributed to contaminated food or water. Proper food preparation can prevent most foodborne diseases. More than 200 known diseases are transmitted through food.1 The World Health Organization (WHO) has long been aware of the need to educate food handlers about their responsibilities for food safety. In the early 1990s, WHO developed the Ten Golden Rules for Safe Food Preparation, which were widely translated and reproduced. However, it became obvious that something simpler and more generally applicable was needed. After nearly a year of consultation with food safety expertsandriskcommunicators, WHOintroducedtheFive KeystoSaferFoodposterin2001.TheFive Keys toSaferFoodposterincorporatesallthemessagesoftheTen Golden Rules for Safe Food Preparation under simpler headings that are more easily remembered and also provides more details on the reasoning behind the suggested measures. The Five Keys to Safer Food Poster The core messages of the Five Keys to Safer Food are: (1) keep clean; (2) separate raw and cooked; (3) cook thoroughly; (4) keep food at safe temperatures; and (5) use safe water and raw materials.

  • 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.

Received 22 September, 2020; Accepted 27 October, 2020 Food additives Azo dyes are synthetic compounds added to foods to impart color and improve their properties. Some azo dyes have been banned as food additives due to toxic, mutagenic, and carcinogenic side effects. Long exposure to foods containing azo dye leads to chronic toxicity. Some microorganisms are capable to degrade these dyes and convert them to aromatic amines. In human body, microbiota can play a vital role in biodegradation of azo dyes by producing azo reductase. Aromatic amines are toxic, water-soluble and well absorbed via human intestine. In the current study, the role of microorganisms in biodegradation of six dyes related to azo group was discussed. These dyes are: Tartrazine E102, Sunset Yellow E110, Ponceau E124, Azorubine E122, Amaranth E123, and Allura Red E129 which are classified as the most harmful food additive dyes. Key word: Food additive, azo dyes, microorganisms, azo reductase, aromatic amines. INTRODUCTION Food additives are synthetic compounds added to food In the USA and European countries, some azo dyes have for many proposes such as maintaining the product from been banned as food additives due to toxic, mutagenic, deterioration or improving its safety, freshness, taste, and carcinogenic side effects (Chung, 2000).

  • What Are Food Additives?
    What are Food Additives? The pursuit of happiness through the enjoyment of food is a centuries old human endeavor. Taste, texture, freshness and eye appeal are major contributors to such enjoyment, made possible in our modern lifestyle through the use of highly specialized ingredients known as food additives. The broadest practical definition of a food additive is any substance that becomes part of a food product either directly or indirectly during some phase of processing, storage or packaging. Direct food additives, which are discussed in this publication, are those that have intentionally been included for a functional purpose by the food processor, whereas indirect additives are those migrating into food products in very small quantities as a result of growing, processing or packaging. Food additives afford us the convenience and enjoyment of a wide variety of appetizing, nutritious, fresh, and palatable foods. Their quantities in food are small, yet their impact is great. Without additives, we would be unfortunately lacking in the abundant and varied foods that we enjoy today. Food Additives – Ingredients with a Purpose Direct food additives serve four major purposes in our foods: 1. To provide nutrition – to improve or maintain the nutritional quality of food. For example, the addition of iodine to salt has contributed to the virtual elimination of simple goiter. The addition of Vitamin D to milk and other dairy products has accomplished the same thing with respect to rickets. Niacin in bread, cornmeal and cereals has helped eliminate pellagra, a disease characterized by central nervous system and skin disorders. Other nutritional food additives (such as thiamine and iron) are used for further fortification in the diet and as a result, diseases due to nutritional deficiencies, common in lesser developed countries, are now very rare in the United States.

Lars Noah* Abstract Under the longstanding FDA policy, the use of genetic engineering in the production of food products generally does not require disclosure in labeling, though sellers would have to reveal if the process introduced any special risks or other material changes. Commentators who criticize this policy often point to the agency's purportedly contrary "precedent" in requiring disclosure whenever foods undergo irradiation. That old FDA rule deserves much of the blame, however, for the fact that irradiation remains seriously underutilized as an effective tool for guarding against foodborne pathogens. If routine GMO food labeling ever became mandatory under either federal or state law, then a similar fate might well befall this newer technology, which is precisely what opponents who involve a "right to know" hope to accomplish. * Professor of Law, University of Florida. GMOs undoubtedly were harmed in the preparation of this Article.
