Abstract

To provide the efficient application scheme of buckwheat dietary fiber and basic information of seed germination, buckwheat(Fagopyrum esculentum Moench) was germinated at 10$^{\circ}C$ for 7 days and the contents and composition of the total dietary fiber(TDF), insoluble dietary fiber(IDF), soluble dietary fiber(SDF) wire examined at 24 hour intervals. The TDF content in ungerminated seeds was 24.86o on dry weight basis. It decreased for the 1st day of germination, but gradually increased for 7 days afterwords. The contents of IDF and SDF in ungerminated seeds were 22.05, 1.42% respectively. The IDF and SDF contents decreased in the initial stage of germination, but then gradually increased. The composition of the IDF and SDF in the TDF during the germination period showed different tendencies. The IDF decreased with germination time until 5 days and then increased. The SDV increased until 5 days and then decreased gradually. The TDF contents obtained by AOAC method were generally higher than those obtained by Prosky method. The TDF contents obtained by the two method, however, were very closely correlated (r=0.9966, p< 0.01) The IDF(X1) and SDF(X2) showed the significant regression equation(p<0.01) with the root length(Y). The equation was Y: -12.6681+0.5089${\times}$ 1 $\div$ 0.6022Xa and R2 was 0.968.
