The salt is free-flowing, colour-stable and may contain much more iron than known products. The dietary salt may contain 0.2-1.5% of colloidal silicic acid. The white colour is preserved even when adding more than 50 mg iron per 100 g. salt, pref. 200-400 mg. iron, pref. in the form of ferricpyrophosphate. |
