EDTA Calcium Disodium

EDTA Calcium Disodium or CaNa2EDTA, a salt of EDTA, is a versatile food additive commonly used as a preservative, chelating agent, antioxidant, flavor enhancer, and color stabilizer in canned foods. EDTA Calcium can bind with free metal ions (such as zinc, iron, copper, magnesium, and manganese) often present in foods and beverages, thereby preventing these ions from reacting with the food and thus preserving its color, flavor, and aroma.

In canned foods, EDTA Calcium Disodium is typically employed as a chelating agent, preservative, and antioxidant (to prevent oxidative degradation via chelation). It stabilizes food by binding free polyvalent metal cations.

Canned foods are processed through canning, sealing, heating, and sterilization to extend shelf life. Common additives in canned foods primarily include preservatives, antioxidants, sweeteners, and synthetic colorants.

EDTA Calcium Disodium helps promote flavor retention and reduces discoloration and turbidity in soft drinks. In vitamin C-fortified beverages, EDTA Calcium Disodium prevents reactions caused by uncontrolled metal ions that can spoil and shorten the shelf life of vitamin drinks. It also aids in preserving antioxidants in vitamins A, B, D, and E.
