Food antioxidants usually used in oil and oil-containing foods.

When using phenol antioxidants, adding certain acids such as citric acid and phosphoric acid at the same time, this can significantly improve the antioxidant effect. These acids are called synergists. Generally considered they can chelation with promote oxidation of trace amount of metal ion, so that it plays a role of antioxidant synergistic.
Synthetic antioxidants, such as ascorbic acid and its sodium salts are safe. The antioxidant role of erythorbic acid and its sodium salt is the same with ascorbic acid and its sodium salt.
