Abstract

The change of free amino acids was identified during fermentation of kimchis (Ixeris sonchifoliaH.) added fermented anchovy. The results were summarized as follows; In fresh roots and leaves of Ixeris sonchifolia H., 8 kinds of free amino were determined respectively. Among them, argine, cysteine and glutamic acid were abundant in fresh roots, while arginine, valine, isoleucine and phenylalanine in fresh leaves, especially arginine was dominant in fresh both roots and leaves. The amount of total amino acids in fresh leaves was about 2.5 times of that of roots. After fermentation, 15 kinds of free amino acids were determined in kimchis, and the characteristic favor of in was attributed to such amino acids as threonine, glutamic acid, alanine, leucine and cysteine. The content of total free amino acids in kimchi leaves was increased to about 5 times of that in fresh (9,435,6mg % on dry base), but in kimchi roots, 11 times of that in fresh was contained (7,079,1mg % on dry base) In kimchi'es extract, 16 kinds of free amino acids were determined, and threonine, glutamic acid, alanine, cysteine and leucine were abundant.
