Abstract

A research was made to investigate the effect of chlorine (Cl) on the Vitamin C (AA) content and on the taste of the chopped cabbage when it was soaksd in Cl containing water. The chopped cabbage was soaked in water containing 0.0, 0.1, 0.5, 1.0 and 1.5 ppm, respectively, from 10 to 30 min. arid the results were as follows : 1) The higher the concentration of Cl and the longer the soaking period, the lower the AA con-tent in samples was. 2) The sample soaked in water for 10 min. was graded as the best taste, and the AA contents were 88. 85. 78. 74 and 72%, respectively, following the increase of Cl in water from 0.0 to 1.5 ppm, as compared with the content of non-soaking. 3) The taste and the smell of top water (Cl content : 0.5 ppm), water filtered through clarifier (0.1 ppm) and distilled water were organoleptically judged, and from this judge, it became clear that the presence of Cl in water significantly affect the taste of water. 4) As to smell, the presence of over 0.1 ppm Cl in water could organoleptically distigushable, but this concentration would not always affect the taste of drinking water or chopped cabbage soaked in this water.
