- the internal structure of the corn cob pulverized product is porous and has a cocoon-cam structure (honeycomb shape), and has many small holes on the partition walls forming pores (Kiyo Ishigooka). Based on the 39th Annual Meeting of the Japan Society for Experimental Animal Engineers), it is presumed that harmful substances are adsorbed in these small holes. In other words, the ability of corn cob pulverized products to remove harmful substances appears to be due to its own internal structure.
- the particle size of the corn cobs pulverized product can be mixed in a filter rod made of a fiber filter material, or a harmful substance removing material can be formed between a plurality of filter rods made of the fiber filter material. It is possible to intervene as a layer and have effective ability to remove harmful substances, and to select as appropriate so that the flavor of tobacco and the good air permeability of tobacco filters can be maintained. And If the particle size is too large, the total surface area of the pulverized product becomes relatively small, and there may occur a situation in which the target amount of the double-stranded DNA cannot be adhered, and in terms of the ability to remove harmful substances.
