Shimeji (Japanese: , or ) is a group of edible mushrooms native to East Asia, but also found in northern Europe. Hon-shimeji (Lyophyllum shimeji) is a mycorrhizal fungus and difficult to cultivate. Other species are saprotrophs, and buna-shimeji (Hypsizygus tessulatus) is now widely cultivated. Shimeji is rich in umami-tasting compounds such as guanylic acid, glutamic acid, and aspartic acid.

Shimeji health benefits

Shimeji mushrooms contain minerals like potassium and phosphorus, magnesium, zinc, and copper. Shimeji mushrooms lower the cholesterol level of the body. This mushroom is rich in glycoprotein (HM-3A), marmorin, beta-(1-3)-glucan, hypsiziprenol, and hypsin therefore is a potential natural anticancer agent. Shimeji mushrooms contain angiotensin I-converting enzyme (ACE) inhibitor which is an oligopeptide that may be helpful in lowering blood pressure and reducing the risk of stroke in persons having hypertension. Also rich in polysaccharides, phenolic compounds, and flavonoids. Therefore, inhibits inflammatory cytokines and oxidative stress and protects from lung failure. These compounds also help in reducing oxidative stress-mediated disease through radical scavenging activity hence these mushrooms are antioxidants also.

Culinary Use

Shimeji should always be cooked: it is not a good mushroom to serve raw due to a somewhat bitter taste, but the bitterness disappears completely upon cooking. The cooked mushroom has a pleasant, firm, slightly crunchy texture and a slightly nutty flavor. Cooking also makes this mushroom easier to digest. It works well in stir-fried foods like stir-fried vegetables, as well as with wild game or seafood. Also, it can be used in soups, stews, and in sauces. When cooked alone, Shimeji mushrooms can be sautéed whole, including the stem or stalk (only the very end cut off), using a higher temperature or they can be slow roasted at a low temperature with a small amount of butter or cooking oil. Shimeji is used in soups, nabe and takikomi gohan.
