Korean fresh elephant -foot (Amorphophalus Konjak K. Koch) and its powder were analyzed and compared with foreign samples for the purpose of investigating the physico -chemical characteristics of Korean konjak. The Korean fresh konjak contains 80.64% of moisture and most of the solid component comprises sugar, protein and trace of fat and fibre. The mannan content of Korean konjak powder is far smaller than those of Japanese and Chinese konjak powder. The analysis of the korean konjak protein tells that 45% of glutamic acid, aspartic acid and argi-nine is included other remaining amino acid is larger with the order of valine, serine, leucine, and gly-cine. The Korean konjak contains a moderate amount of K component and other inorganic component increases with the order of P Na and Ca. The yield of konjak refined powder from dried chip was 61% and 51.5% of korean and chinese re-spectively. The whiteness degree of chinese konjak powder was slightly higher than that of korean product but the difference could not be recognized by the naked eye.
