Total vitamin C content in frozen and cooked vegetables measured by HPLC was only 47.5% of that measured by the colorimetric method. Such an overestimation of vitamin C of prepared vegetables by the colorimetric method was due to the color development from other compounds such as 2, 3-diketogulonic acid, seasonings, sugar and starch. Total vitamin C content in cooked vegetables from commercial sources measured by HPLC should be one third to one fifth of that in fresh vegetables."}, pages = {67--76}, title = {"新鮮野菜,冷凍野菜および市販惣菜のビタミンC量 : DNP比色法とHPLC法による定量値の比較"}, volume = {47}, year = {2001} }
