What is disodium EDTA used for?
It’s a popular food additive, used as a preservative and flavoring agent. Calcium disodium EDTA works as a chelating agent. This means it binds to metals and prevents them from participating in chemical reactions that might cause discoloration or flavor loss.
Why is disodium salt of EDTA is preferred to EDTA?
The disodium salt of EDTA is preferred in hardness estimation mainly because it is more soluble in aqueous solutions which allows release of the EDTA ligand into solution to react.

Ethylenediamine tetraacetic acid
Ethylenediamine tetraacetic acid (EDTA) is a polyprotic acid containing four carboxylic acid groups and two amine groups with lone-pair electrons that chelate calcium and several other metal ions. Specific data on the behavior of EDTA as an anticoagulant in hematology, including possible pitfalls, are presented.
What is EDTA used for in food?

How do you make EDTA?
EDTA Solution Preparation and Recipe
- Prepare 800 mL of distilled water in a suitable container.
- Add 11.7 g of EDTA to the solution.
- Slowly adjust the pH to 8.0 with 2 M NaOH. (Unless using the salt, EDTA often requires extended time and basic pH conditions to completely dissolve.) Store for up to 3 mo at 4°C.
How bad is EDTA?
EDTA can cause abdominal cramps, nausea, vomiting, diarrhea, headache, low blood pressure, skin problems, and fever. It is UNSAFE to use more than 3 grams of EDTA per day, or to take it longer than 5 to 7 days. Too much can cause kidney damage, dangerously low calcium levels, and death.
