几种常见野菜亚硝酸盐含量分析研究

采用盐酸萘乙二胺法测定了4种常见野菜:苣荬菜、萎陵菜、蒲公英、猪毛菜的亚硝酸盐含量。通过不同处理来比较野菜鲜样和漂烫后亚硝酸盐含量的差异。结果表明:这4种野菜的亚硝酸盐含量均低于世界卫生组织和联合国粮农组织规定的亚硝酸盐ADI值,所以可以安全食用。经漂烫处理后,各种野菜的亚硝酸盐含量变化有很大差异,猪毛菜的亚硝酸盐含量有所减少,苣荬菜的亚硝酸盐含量几乎不变,而萎陵菜和蒲公英的亚硝酸盐含量均有所增加。因此,人们在食用时也要注意选用合理的食用方法。

Analysis on Contents of Nitrite in Several Common Wild Vegetables

The way of hydrochloric acid naphthalene ethylene diamine the content of nitrite in wild vegetables was determined.Four kinds common wild vegetables were showed as Sonchus arvensis L.,Potentilla Chirensis Ser,Taraxacum mongolicum Hand.-Mazz,and Salsola collina Pall..By different treating,the nitrite contents were compared betwecn the wild vegetable of flesh type and being burned in hot water.The result indicated that the nitrite contents of these wild vegetables were lower than the nitrite ADI value which w...
