Iron-boxed food, except for a few light-colored fruits and canned fruit juice, mostly uses empty cans coated with internal paint to improve the corrosion resistance of containers; however, due to the electrochemical effect of metals, a small amount of iron dissolves from canned food without internal coating in storage, and exists in sealed canned food in the form of iron bivalent. It is absorbed easily by human body. The content is about 1 to 10 ppm. As far as raw fruit and vegetable products are concerned, their iron content is not much. The iron box products cooperated by Huangjiang used car are calculated by 350 ml beverage iron box per pot. The iron content is calculated by ppm. Each pot can supply 1.75 mg of iron, which is about one tenth of the daily intake of 18 mg by human body.
