Most edible fungi grow naturally and are collected manually. Edible fungi can be made into all kinds of delicious food after careful cooking. Some edible fungi also have the effects of anti-cancer and treating many diseases, so they are generally welcomed by people. Among the traditional dishes in China, edible fungi is a rare "delicious food" and a popular healthy food. At present, there are more than 2,000 kinds of known edible fungi in the world. China has a vast territory, which is composed of cold regions, temperate regions, subtropics and tropics, and has bred a large number of wild edible fungi with rare protection value and economic value. About 98 1 species have been reported, belonging to 48 families 136 genera. At present, more than 70 species can be cultivated artificially, and more than 20 species can be commercialized and industrialized on a large scale. At present, there are more than 50 kinds of precious wild edible fungi with high economic value and delicious taste. There are dozens of wild edible fungi that can be exported in large quantities, such as Tricholoma matsutake, Lentinus edodes, Boletus edulis, chicken termites, chanterelles, truffles, dictyophora and so on. Wild edible fungi resources are very rich.

Truffles, Tricholoma matsutake, Carapax Trionycis, Morchella esculenta and Boletus deliciosa, which are known as the top five bacteria kings in the world, cannot be commercialized at present. Can only be obtained from nature.

China domesticated and cultivated Lentinus edodes, Auricularia auricula, Auricularia auricula, Tremella fuciformis, Volvariella volvacea, Flammulina velutipes, Hericium erinaceus and Dictyophora dictyopteris for the first time in the world, and now domesticated Tricholoma mongolica. Wild edible fungi such as Boletus edulis, Morchella esculenta, Pleurotus ostreatus and so on can also be collected and supplied to domestic and foreign markets in large quantities.

So what's the difference between wild mushrooms and artificially cultivated edible mushrooms in health care function? What should consumers pay attention to when buying?

Shi Mubiao, an associate professor in the Department of Food Science of South China Agricultural University, pointed out: Generally speaking, due to the influence of natural conditions such as temperature, sunshine, topography and cycle, wild mushrooms are rich in amino acids, protein and other effective components, as well as trace elements such as copper and zinc. Different kinds of wild mushrooms contain different elements, such as russula. Wild russula has high iron content and good blood-enriching effect. Long-term consumption can not only strengthen the body, but also help beauty beauty. So far, it is impossible to cultivate the same effect of Russula by artificial means. Wild fungi often have trace elements that artificial cultivation does not have. For example, wild Cordyceps contains not only polysaccharides, but also elements such as cordycepic acid and cordycepin. These elements contain (super oxidase), which can eliminate free radicals, improve human immunity and play a significant role in the prevention and treatment of cancer.

Does artificially cultivated edible fungi have health care function? According to the enrichment effect, if the growth conditions of wild fungi are simulated in the planting process, copper, zinc, strontium and other elements can be added appropriately, which can also play a certain health care role. Because wild mushrooms have their unique growth conditions, edible mushrooms that can be artificially cultivated by simulating the growth conditions of wild mushrooms are also very different from wild mushrooms in health care function. What's more, it is an edible fungus cultivated under artificial conditions.

Take Ganoderma lucidum as an example: the growth period of artificially cultivated Ganoderma lucidum is very short, the same strain is inoculated many times, pesticides are widely used, and the base material changes, so that the artificially cultivated Ganoderma lucidum often has its own shape but nothing. For example, the most important component of Ganoderma lucidum's anti-tumor and anti-aging immunity is organic germanium, which is not contained in cultivated Ganoderma lucidum, and the polysaccharide content is only about 1/3. The content of ganoderic acid with strong pharmacological activity is very low, and there are great differences in various trace elements, and the activities of various effective components are extremely low. Whether wild ganoderma lucidum is better or cultivated artificially, we don't need to explain which is right or wrong. You can judge for yourself. Of course, some experts and scholars will stand up and say whether Ganoderma lucidum is good or artificial. It can only be said that from a commercial point of view, he will have various reasons to fully explain that artificial ganoderma lucidum is good, and the so-called wild is poisonous. If he really wants to collect such treasures on the mountain, he will be willing to give up. If you can pick wild ones, will you throw them away? Natural selection, a gift from nature, is "what can be met but not sought"
