Shiitake not only contains fat, carbohydrates, protein, but also contains more than 10 kinds of amino acids, including 7 kinds of essential amino acids such as isoleucine, lysine, phenylalanine, methionine, threonine and valine, vitamins B1, B2, PP, mineral salts and crude fiber, etc. However, the key component is polysaccharide called lentinan. Lentinan is a brown-yellow powder extracted from the crushed mycelium of Lentinus edodes, which is rich in polysaccharides and lignin. The mushroom products produced after crushing have many functions by using mycelium that appears before the growth of the top cover and stem of the mushroom.
