Applications
1. Food Antioxidant And Preservative: As E385 and INS 385 it stops metal ions from catalysing discolouration and off flavours in mayonnaise, sauces, margarines, canned vegetables, legumes and seafood, and it works as a stabiliser plus a colour and flavour retention aid.
2. Anti-Gushing Agent For Fermented Malt Beverages: In brewing it is used as an antigushing agent for fermented malt beverages, one of the specific permitted uses listed for calcium disodium EDTA in the US food additive regulation for the additive.
3. Chelant That Spares Calcium: The ligand arrives already complexed with calcium, so it captures trace iron and copper without stripping calcium out of the product, which is why it is chosen where calcium depletion has to be avoided.
4. Chelating Agent For Cosmetic And Personal Care: It appears among the cosmetic ingredients found safe as used in the CIR review, and its chelating function is comparable to disodium EDTA, so formulators can use it as the calcium complexed alternative.
