Abstract
|
|
|
|
A total of 550 samples were analysed for nitrate contents using HPLC-UV. Nitrate contents of leaf vegetables were higher than those of root vegetables and fruit vegetables. The average nitrate content of the radish leaves (4875.8 ㎎/㎏) was the highest, followed by marsh mallow (4711.7 ㎎/㎏), crown daisy (4546.9 ㎎/㎏) and vitamins (4239.5 ㎎/㎏). The nitrate content in fruits of strawberry and banana averaged at 24.0 ㎎/㎏ and 438.5 ㎎/㎏, respectively. Nitrate was not detected in other fruits. In fruiting vegetables nitrate contents were less than 1000 ㎎/㎏. In onion, lotus root and radish, nitrate contents were 253.7㎎/㎏, 352.4㎎/㎏ and 2849.0 ㎎/㎏, respectively, with no detection in garlic. Nitrate contents in mushrooms were less than 100 ㎎/㎏.
