Wash vegetables bubble difficult a long time residues of pesticides Increase the carcinogenic probability of inferior nitrate instead
A lot of people washed the vegetables, liked putting in the fresh water and soaked for some time, thought it cleaner like this, taste of high quality. Vegetables soak, wash and then for a long time, can not clean the residues of pesticides in fact, will even make inferior nitrate of carcinogen increase.
It will make the content of inferior nitrate increase to soak the vegetables for a long time. The intersection of Anhui and agricultural finding of university, soak after the 20 minute with fresh water, inferior the intersection of nitrate and content in the vegetables higher than, spend, wash clean to wash while being precise, then rinse the clean vegetables. The research has suggested, there is not oxygen state to it is one to soak, help to improve the activity of reductase nitric acid, reduce the activity of inferior nitrate reductase, thus improve the content in the vegetables of inferior nitrate. Finally, long-time soaking may also enable the blade damage of the vegetables, increase nutrition losses.
A lot of experts warn, inferior nitrate in the vegetables will probably remain more harmful than pesticide. Because excessively use the nitrogen, the content of nitrate in the vegetables is often a bit high, after transforming into inferior nitrate, may become the carcinogenic hidden danger.
