Where can I purchase calcium disodium edta preservative? - Young couple selecting food in market

I'm trying to make homemade mayonnaise with a longer shelf life. I see all the commercial brands list calcium disodium edta as a preservative so I was wondering where I could find this ingredient.

I see it being sold as a supplement on bulksupplements.com but I get the feeling that this isn't what I'm looking for.



Best Answer

Calcium disodium edta is added to food items as a preservative and flavoring agent. However, don't assume that "preservative" means an ingredient keeps your food safer longer. This particular preservative is probably added to maintain color and flavor, rather than to extend shelf life. Homemade mayonnaise is a product with a fairly short shelf life...generally only a few days in the fridge, even if you are making an egg-less version. There are online recipes for lacto-fermented mayonnaise, which could extend that life for up to a month. Maybe try that route....or make less mayo more frequently.
