1 How did the bamboo fungus turn brown without opening the bag

It may be oxidized.

Bamboo fungus contains a lot of polysaccharide components, in the process of placing it is easy to oxidation reaction with the oxygen in the air and discoloration, so normally the bamboo fungus is slightly yellow, and with the prolongation of the placing time, the color will gradually deepen.

However, if the bamboo fungus is sealed in a bag, because of the isolation of the air, the bamboo fungus will not change color so quickly, if the bamboo fungus has not yet opened the bag on the brown, generally because the bag is damaged, resulting in the bamboo fungus and the reaction of oxygen caused by.

2 Can you eat bamboo fungus when it is brown

You can eat it, but it is not recommended.

If the bamboo fungus has turned brown, it proves that it has been placed for a long time. If the color of the bamboo fungus is only slightly deepened, but its texture is still very dry, and there is no abnormal mold or hair on the surface, then you can continue to eat it.

However, because the nutrients contained in bamboo fungus will be lost over time, the nutritional value of eating it is not very high, so it is not recommended to eat it again.

3 Does bamboo fungus need to be soaked

Dried bamboo fungus needs to be soaked.

Bamboo fungus is a kind of edible fungus, for the fresh bamboo fungus, the moisture content is large, so the shelf life is relatively short, usually it is dried and made into dried products for transportation and sale.

The dried bamboo fungus needs to be soaked before cooking. After soaking, the bamboo fungus will absorb water and expand, and the texture will become soft, so that it tastes as crispy and tender as the fresh products, and the taste is also very good, and the nutrition will not be too much loss.

4 How long does it take to soak bamboo fungus best

Cold water for 30 minutes, and lukewarm water for 15 minutes.

Compared to other dry products, the water absorption speed of bamboo fungus is still relatively rapid, it is easy to absorb water and expand, and generally speaking, the longer the soaking time, the nutritional loss is also more, so in order to ensure that the nutrients of the bamboo fungus do not lose too much, soaking time is not too long, generally need to be based on the temperature of the water to decide.

If it is soaked in cold water, it usually takes about 30 minutes; if it is soaked in warm water, it usually takes about 15 minutes.
