It is now very important that we have to explore the excellency of Korean traditional foods and to hand down the taste of it to the next generations, because the shapes of the foods or the foods themselves are fading out on the ground that the western style of foods are spreading very widely. However, the realistic research about the foods are very slight and the data of the systemic investigation and excavation about the Korean traditional foods are very short. In addition to this, we are need to investigate, excavate, and accumulate the data for the foods when there are persons who has some experience about how to cook and know-how about the actual foods in order to prepare the international reservation for [an agreement of biological diversity], which was signed at Riu, Brazil. The research is done at the province of Chungchung from March to December, 2001. We observed the foods of the province, separating it into Chungchun-namdo and Chungchung-bukto. We collected the kinds of foods by the questionnaire or the field investigation, and we studied the historical evidence for them conferring the books about the foods( for instance, Whang, Hae-Sung and others). And we took the pictures on the process of making foods that the initiate experts are demonstrating. The kinds of traditional foods in Chung-buk were 158 foods, of which main dishes were 42 including Pyogo busutbap, and side dishes are 93 including Guysan-chu-tang, and preferences were 26 including Chik-bu-kku-mi, based on the conference books. However, our excavation and investigation shown that traditional foofs of Chung-buk were 95 kinds, of which main dishes were 18 including Keingsengi-ju, and side dishes were 44 including Jinip-kimchi, and preferences were 33 including Gamtto-gaetteok. However, the questionnaire shown that the kinds of traditional foods of Chung-nam were 342, of which main dishes were 53 including Kukijasun-bibim-bap, and side dishes were 202 including Kkokgeial-teonjang-kuk, and preferences were 90 including Hodu-kawja. However, our excavation and investigation shown that the traditional foods of Chung-nam were 90 kinds, of which main dishes were 8 including Ssuk-bap, and side dishes were 64 kinds including Hobak-geikukji, and preferences were 21 kinds including Yeohyangchia.
