Now I can tell you for sure that it is edible, but the premise is that it has not been eaten! The content of nitrite in the prepared tremella aurantialba soup was close to mg/L at that time, and it was only about .25mg/L after 24 hours and 48 hours of sealed storage, which was much lower than the standard of fresh vegetables (the standard of pollution-free vegetables was lower than 4mg/kg).

2. How long can the tremella soup be stored in the refrigerator at most?

Through the above experiments, you can find that the best storage method is to seal it and refrigerate it in the refrigerator for 1-2 days, which is ok, and it is best not to drink it if it is kept for more than 3 days. It can be seen intuitively in the article that after 48 hours, the nitrite content in tremella aurantialba soup increases obviously, so it is best not to keep it for more than 48 hours.

3. How many tremella can people eat every day?

The normal consumption is not more than 6 grams of dried food, and about 6 grams after rehydration. 6 grams of dried tremella can probably cook 1 catty of thick tremella soup. According to our experimental colorimetric results, the content of nitrite in 1 kg of thick tremella decoction is about .6 mg. The dose of nitrite poisoning in adults is .3～ .5g, which is quoted from the public health management in China, which is equivalent to eating 5 kg of tremella decoction at least once. Even if you eat a bowl of tremella in the morning and evening, the amount of nitrite you eat in your body is not as high as that of a ham sausage!
