Edible fungi are edible mushrooms; Mushrooms refer to higher fungi that can form large fleshy (or gelatinous) fruiting bodies or sclerotia.
Edible fungi are rich in protein and amino acids, the content of which is several times to dozens of times that of ordinary vegetables and fruits. For example, the protein content of fresh mushrooms is 1.5-3.5%, which is 3 times that of Chinese cabbage, 6 times that of radish and 17 times that of apples. 1 kg of dried mushrooms contains protein equivalent to 2 kg of lean meat, 3 kg of eggs or 12 kg of milk. Lysine in edible fungi is very rich, including 18 kinds of amino acids that make up protein and 8 kinds of trace elements necessary for human body. The content of lysine in cereal food is low, and the content in edible fungi is also quite rich. The fat content of edible fungi is very low, accounting for about .2%-3.6% of the weight of dried products, and 74-83% of them are unsaturated fatty acids beneficial to human health. Edible fungi also contain vitamins. Edible fungi are rich in VB1 and V12, which are higher than meat. The Vc content of Volvariella volvacea is 1.2 ~ 2.8 times that of pepper, 2 ~ 5 times that of pomelo and orange, and 17 times that of Lentinus edodes. The original Vd content of Lentinus edodes is as high as 128 international units, which is 8 times that of laver, 7 times that of sweet potato and 21 times that of soybean. VD can be transformed into VD by ultraviolet irradiation, which promotes the absorption of calcium. Edible fungi are also rich in a variety of mineral elements: phosphorus, potassium, sodium, calcium, iron, zinc, magnesium, manganese, and other trace elements. Tremella contains more phosphorus, which helps to restore and improve brain function. Mushrooms and auricularia auricula have high iron content. The potassium in the ash element of shiitake mushroom accounts for 64%, which is a high-grade food in alkaline food and can neutralize the acid produced by meat food. Edible mushrooms are not only delicious, but also nutritious, and are often called healthy foods. For example, mushrooms not only contain various essential amino acids, but also have the functions of lowering blood cholesterol and treating hypertension. In recent years, it has also been found that mushrooms, mushrooms, Flammulina velutipes and Hericium erinaceus contain substances that enhance the anti-cancer ability of human body.
