Abstract: Acorn can be found in many parts of our country in great quantity. Tannic substance is one of the major components of acorn, which can produce sediment with Pb2+ and cause adsorption to other forms of heavy metals. This paper aimed at the research on the lead-resistance function of the tannic substance that was rich in acorn. By means of such methods as of physical, chemical or animals experiment, to study the reliable theoretical basis for the new technology of removing or preventing lead- poison in this sense for further research on the health care food-acorn, this paper would be of some initiative value both in theoretical research and in practical use.

Key words: acorn, health care food, lead removing
