摘要:

本实验研究用铝、氧化铝、铁和不锈钢炊具煮沸硝酸盐水溶液及烹调蔬菜过程中,硝酸盐转变成亚硝酸盐的转化率。结果平均转化率最高的为铝炊具:水溶液为2.27%、蔬菜为0.06%;最低的为不锈钢炊具:水溶液为0.06%、蔬菜为0.001%。从防癌的观点,不锈钢炊具为最好。

Abstract:

The trausfomation of nitrate to nitrite was studied. When nitrate solution or vegetables were cooked with utensi1s made of different materials like aluminum, aluminum oxide, iron and stainless-steel respectively. Cooking either nitrate solution or vegetables with utensils made of aluminum, the transfomation rates were the lowest, 0.07% and 0.0028% respectively. Therefore utensil made of stainless-steel was the first choice fur cooking.
