The present invention relates to a method for producing traditional adhesives for restoration of cultural properties and recorded materials excellent in preservability, flexibility, color, adhesion and reversibility by optimizing starch through enzyme hydrolysis and electron beam treatment, and a conventional adhesive prepared thereby.The conventional adhesive of the present invention can produce a paste exhibiting constant antimicrobial activity and improve the phenomenon of deterioration due to acidity caused by mold or microbial fermentation and the yellowing phenomenon and drastically shorten the long process by the conventional conventional method By overcoming the difficulties of production standardization due to long process and establishing mass production system of traditional adhesive with certain standard, it is possible to bring about the effects of import substitution as well as foreign currency saving through overseas exports.;
