Disclosed is a porous adhesive for corrugated cardboard, including sticky starch and porous zeolite, in which microscopic holes to be joined with the microscopic holes in zeolite are formed in starch, thereby maintaining the freshness of food products stored in a corrugated cardboard box and efficiently eliminating remaining agricultural chemical components. Also, a method of manufacturing corrugated cardboard using the porous adhesive is provided. The porous adhesive for corrugated cardboard is obtained by blending a mixture, including 68.5.about.79.5 wt % corn starch, 20.about.30 wt % zeolite powder having the same particle size to that of the corn starch, and 0.5.about.2 wt % microorganism-containing yellow soil, caustic soda and a box hardener, with water. The zeolite powder and the corn starch have a particle size of 300.about.350 meshes. The microorganisms contained in yellow soil are selected from the group consisting of Bacillus sp., Acinetobacter sp., Pseudomonas sp., and mixtures thereof.
