AL Chemistry Project No. 9
The Use of EDTA
in
Food Industry and Chelation Therapy
Group members:

EDTA
Ethylenediaminetetraacetic acid Chelating agent Mostly synthesized from
1,2-diaminoethane, formaldehyde,
water and sodium cyanide
Uses of EDTA
Food industry Personal care Oil production Dairy and beverage indu
stry Flue gas cleaning Chelation therapy
Industrial cleaning Detergents Photography Pulp and paper industry Textile industry Agrochemicals Hydroponics
Food Industry
Added as preservativeApproved to use in packaged foods, vitami
ns, 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
Food Industry
Soft drinksContain ascorbic acid and sodium benzoate
To alleviate formation of benzene (a carcinogen)
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
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
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
