On the Internet on the "hair good fungus overnight can not be eaten" a popular saying is that the nitrate in the fungus will be reduced to nitrite, and nitrite is a toxic substance, there is a great risk of cancer.

In order to prove that the reporter from the market randomly purchased a bag of silver fungus, from which to take out two copies, one soaked and placed for 12 hours, another soaked and placed for 24 hours. Subsequently, the reporter will send two samples of silver fungus to the Beijing Physical and Chemical Analysis and Testing Center for nitrite testing, so the silver fungus overnight will really produce a lot of nitrite?

4 days later, the reporter got the test report, according to the provisions of the national food nitrite limit standards, vegetable foods in the nitrite content shall not exceed 4mg per kilogram, and the reporter got the test data show that, whether it is hair after 12 hours or hair after 24 hours of the silver fungus, the content of nitrite is less than 1mg per kilogram, are in line with safety standards.

And the inspector told reporters that according to industry standards, less than 1mg per kilogram can be regarded as not detected. Capital Medical University Affiliated Anzhen Hospital clinical dietitian Wu Xiaoling told reporters silver fungus does contain nitrates, hair after placing for a long time will indeed produce nitrites.

So why did the reporter send a sample, the detected nitrite content is small to almost no? In this regard, China Agricultural University food science Dr. Fan Zhihong explained that, because of the silver fungus in the soaking process, nitrate will be diluted by water, so even if it will produce nitrite, the content is also very small, it will not cause harm to our bodies.

Experts reminded that although the hair of the silver ear after overnight should not be eaten is not correct, but the hair of the silver ear if placed too long, easy to breed bacteria, it is recommended to cook and then eat.
