Iron gluconate: why did you want it in there, why do you do it and is it safe for your health? 👀
Hi PatJ, thanks for your question about iron gluconate. Our black olives start out as green olives. We blacken them through a natural oxidation process with atmospheric oxygen. We stabilize them with ferrous gluconate (E 579) to ensure that the beautiful, uniform black color is retained and does not turn greyish-brown. It not only provides the color, but also ensures that the olives remain crisp. Best regards, your M-Infoline team
