Shimeji

Shimeji (Japanese: シメジ, 占地 or 湿地) is a group of edible mushrooms native to East Asia, but also found in northern Europe.[1] 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.[2]

Species

Several species are sold as shimeji mushrooms. All are saprotrophic except Lyophyllum shimeji.

Mycorrhizal
The cultivation methods have been patented by several groups, such as Takara Bio[3] and Yamasa,[4] and the cultivated hon-shimeji is available from several manufacturers in Japan.[5][6][7]

Saprotrophic
  • Buna-shimeji (ブナシメジ, lit. beech shimeji), Hypsizygus tessulatus, also known in English as the brown beech or brown clamshell mushroom.
    Hypsizygus marmoreus is a synonym of Hypsizygus tessulatus. Cultivation of Buna-shimeji was first patented by Takara Shuzo Co., Ltd. in 1972 as hon-shimeji and the production started in 1973 in Japan.[8] Now, several breeds are widely cultivated and sold fresh in markets.
  • Bunapi-shimeji (ブナピー), known in English as the white beech or white clamshell mushroom.
    Bunapi was selected from UV-irradiated buna-shimeji ('hokuto #8' x 'hokuto #12') and the breed was registered as 'hokuto shiro #1' by Hokuto Corporation.[9][10]
  • Hatake-shimeji (ハタケシメジ), Lyophyllum decastes.
  • Shirotamogidake (シロタモギダケ), Hypsizygus ulmarius.
    These two species had been also sold as hon-shimeji.
  • Velvet pioppino (alias velvet pioppini, black poplar mushroom, Chinese: 茶樹菇/茶树菇), Agrocybe aegerita.

Shimeji health benefits

Shimeji mushrooms contain minerals like potassium and phosphorus, magnesium, zinc, and copper. Shimeji mushrooms lower the cholesterol level of the body.[11] This mushroom is rich in glycoprotein (HM-3A), marmorin, beta-(1-3)-glucan, hypsiziprenol, and hypsin therefore is a potential natural anticancer agent.[12][13] 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.[14] Also rich in polysaccharides, phenolic compounds, and flavonoids. Therefore, inhibits inflammatory cytokines and oxidative stress and protects from lung failure.[15] These compounds also help in reducing oxidative stress-mediated disease through radical scavenging activity hence these mushrooms are antioxidants also.[16]

Cooking

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.[17] 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.
