To investigate nutritional and biochemical values of buckwheat, amino acids and minerals in buckwheat harvested from Kangweon-do were analysed. Mixed flour between buckwheat and wheat were made to be used for buckwheat noodle and were also analysed minerals and major nutrients in composite flours. When three different levels of flour mix were compared, major nutrients were about same among those mixes but minerals were higher by adding more buckwheat flour, especially by adding more imported buckwheat flour. From this mixed flour, 9 minerals and 16 amino acids including 9 essential amino acids were analysed. Contents of selenium, sodium and magnessium were very high in buckwheat flour, Therefore, nutritional value of domestic buckwheat was highly evaluated. BAP method was used to determine the change of gelatinization in the noodles prepared by extruder at 8$0^{\circ}C$, and in the noodles during freeze drying and refrigeration. 70% of gelatinization was done during noolding process and retrogradation was severe during refrigeration.
