This study was carried out to compare the change of free amino acid content in the radish Kimchi added with anchovy pickle sauce with that added with 15% NaCl solution during 30 days fermentation. RESULTS : 1. During the fermentation, the pH of both sample A and B showed the highest values of 7.3 and 7.1, respectively, and then both decreased continually to the lowest value of 4.2 at the 30th day. 2.The salinity in the juice of sample A was higher than that of sample B in all the steps during fermentation, accompanied with a slight decrease of the salinity in both cases with time elapsed. 3. The free amino-type nitrogen content of sample A was nearly duplicated in the final step than in the initial one,while that of sample B showed no significant changes in all the processing period. 4. The free amino acids detected in the both samples were aspartic acid, threonine, serine, proline, glutamic acid, glycine, alanine, tyrosine, cysteine, valine, methinonine, isoleucine, leucine, phenylalanine, $\gamma-aminobutyrix acid(\ulcorner), ornithine, lysine, histidine and arginine. 5. The amounts of proline, arginine were the highest in all free amino acids during fermentation, and tasty components of radish Kimchi seemed to relate to glutamic acid, alanine, isoleucine, leucine, phenylalanine, more deliciousness of Kimchi A and B seemed to derive from amino acids of anchovy pickle sauce added to Kimci A, such as alanine, valine, phenylalanine, lysine.
