Abstract
This study was to investigate physicochemical properties of Shinan seomcho growing in Jeollanamdo. The samples used were Shinan seomcho(Josaeng, Mansaeng varieties), Pohangcho(Josaeng, Mansaeng varieties), Namhaecho (Josaeng, Mansaeng varieties) and greenhouse spinach(Josaeng varieties). The results were as follows ; The thickness of spinach leaves were contained in order of Shinan seomcho > Pohangcho > Namhaecho > greenhouse spinach, and the hardness of those were contained in order of Pohangcho > Namhaecho > Shinan seomcho > greenhouse spinach. In Hunter's color value, L, a, b value in greenhouse spinach was lower than those of the others. Among the spinach varieties, Josaeng-jong(3.39~5.38 mg%) had the highest level of total dietary fiber contents than that of Mansaeng-jong(2.94~3.91 mg%). By regional groups, total dietary fiber were contained in order of Pohangcho > Namhaecho > Shinan seomcho > greenhouse spinach. The free sugar contents in the sample group, Shinan seomcho(4 varieties), Pohangcho(1 variety) and Namhaecho(2 varieties) were higher than those of other spinach varieties. The total sugar contents in the sample group, Shinan seomcho(3 varieties), Pohangcho(1 variety) and Namhaecho(2 varieties) were higher than those of other spinach varieties. Total flavonoid contents of Shinan seomcho(Josaeng-jong) and Namhaecho(Josaeng-jong) were lower than 130 mg%, but the other spinach had more than 130 mg% of total flavonoid contents. Germanium contents were detected in the following order ; Shinan seomcho(47.46 ${\mu}g$/kg) > Namhaecho(30.13 ${\mu}g$/kg) > Pohangcho(26.39 ${\mu}g$/kg) > greenhouse spinach(25.32 ${\mu}g$/kg).
