Is it toxic to eat cold black fungus without blanching it?

Fresh black fungus is poisonous. Dried black fungus is not poisonous. Soaked dried black fungus is non-toxic and can be eaten raw, but in terms of health and safety and nutrient absorption rate, it is best to blanch and cook the black fungus before mixing it with cold dishes. Eating black fungus raw cannot fully absorb its nutrients, which puts a heavy burden on our stomach and intestines and is not good for gastrointestinal health.

Blanching can reduce some phototoxic substances. Fresh fungus contains more porphyrin, which is a substance that is very sensitive to light and will decompose and produce some harmful substances under strong light.

During the drying process of fresh fungus, most of the porphyrin substances will be decomposed, so the porphyrin content in dried fungus is very low.

It is recommended to blanch the black fungus before eating it, because high temperature blanching can destroy most of the porphyrins.

What should I do if I soak too much black fungus? How should I preserve it?

If the black fungus is soaked for a long time, you can put it in a fresh-keeping box with water, put it in the refrigerator, keep it at about 5 degrees, and it can be stored for 2-3 days. You can also put the soaked black fungus in the sun until it is completely dry, put it in a fresh-keeping bag, and store it in a cool and dry place. If the soaked black fungus is not handled in time, it is easy to rot and mold.

How to eat fresh fungus safely

Fresh fungus needs to be washed, blanched or exposed to the sun before it can be eaten. Fresh fungus contains porphyrin, a photosensitive substance that reaches the epidermal cells after being eaten by the human body. Symptoms such as solar dermatitis and rashes will occur after exposure to the sun. Porphyrin substances are insoluble in water, but they can be decomposed by themselves after exposure to the sun, so it is recommended to buy dried fungus that has been exposed to the sun.

Wash the fresh black fungus, put it in a pot with water and blanch it for about 1-2 minutes without covering the pot, then rinse it 2-3 times.

Alternatively, you can place fresh wood ear mushrooms in the sun to dissolve the toxic substances, then soak and wash them before using them for cooking.
