  1. AL Chemistry Project No. 9 The Use of EDTA in Food Industry and Chelation Therapy Group members: Leung Hoi Yan 7S (18) Ling Wing Yee 7S (21)

  2. EDTA • Ethylenediaminetetraacetic acid • Chelating agent • Mostly synthesized from 1,2-diaminoethane, formaldehyde, water and sodium cyanide

  3. Uses of EDTA • Industrial cleaning • Detergents • Photography • Pulp and paper industry • Textile industry • Agrochemicals • Hydroponics • Food industry • Personal care • Oil production • Dairy and beverage industry • Flue gas cleaning • Chelation therapy

  4. Food Industry • Added as preservative • Approved to use in packaged foods, vitamins, and baby food • To prevent catalytic oxidation by metal ions or stabilizer and for iron fortification • Deactivates enzymes by removing the metal ions from them and forming stable chelates with them

  5. Food Industry • Soft drinks • Contain ascorbic acid and sodium benzoate • To alleviate formation of benzene (a carcinogen)

  6. Chelating Agent • A substance whose molecules can form several bonds to a single metal ion • The most common and most widely used chelating agents are those that coordinate to metal ions through oxygen or nitrogen donor atoms, or through both Metal-EDTA chelate

  7. Chelation Therapy • Chelation involves the two nitrogen atoms and two oxygen atoms in separate carboxyl (-COO¯) groups • Administration of chelating agents to remove heavy metals from the body • For treating acute heavy metal poisoning

  8. Chelation Therapy • Convert toxic metal agents to a chemically inert form that can be excreted without further interaction with the body • Administered intravenously, intramuscularly or orally • Combined with chromium to evaluate kidney function • Used as anticoagulant for blood samples
