This study was performed to investigate the natural contents of sulfite in vegetables and fruits. Experimental subjects included 351 cases of vegetables and 59 fruits collected in 4 areas-Jeonbuk, Kyungnam, Chungcheung and Kangwon-from October to December in 1987. Sulfite of the subjects were determined by ion chromatography rapidly and precisely. Mean value of sulfite contents in leaf-vegetables, green onion was the highest value, 13.23±1.39 ppm. Garlic was the highest value, 134.07±9.65 ppm in root-vegetables. Green pepper in fruit-vegetables was the highest value, 1.16±0.12 ppm. In the fruits, persimmon was the highest, 2.74±0.45 ppm. There were some differences among the areas. The mean value of sulfite contents in vegetables and fruits collected in the Chungcheung areas were higher than that in other places.
