What is Lentinula edodes or Shiitake?

Lentinula edodes or shiitake, the Japanese and most common name worldwide, is a delicious and very popular edible and medicinal mushroom. In Japan and China, this mushroom has been regarded for centuries as the “elixir of life” that promotes vitality and energy. Shiitake is a source of several compounds with proven pharmacological properties, including some interesting polysaccharides.

Lentinula edodes has a number of therapeutic properties such as support of the immune system (cell-regulating activity), prevention of cardiovascular diseases and diabetes. It also possesses antioxidant, anti-inflammatory and liver-protective properties, and has a beneficial effect on bronchitis and allergies.


Why choosing Lentinula edodes (Shiitake) through submerged fermentation?

Submerged cultivation is the best technology to manage the identity and purity of medicinal mushrooms without contamination. The bioactive substances of mushrooms are identified not only in the fruit body, but also in the mycelium culture and broth.

The most powerful ß -glucans are found in the mycelium, because the defence of the mushroom is most needed in the substrate. They are the so-called branched ß- 1,3-1,6 glucans.

After long and complex research, it has been possible to make liquid substrates for the different mushrooms where the mycelium can develop under ideal conditions. A sterile and liquid substrate is used where the mycelium is introduced and further develops for several weeks. When the mycelium is fully developed, everything is filtered. The filtration removes the not converted liquid substrate, but also the less active ß -glucans. Low-temperature membrane filtration with a molecular weight cut-off (MWCO) of 5,000 Da produces high-molecular ß-glucans that are highly bioactive. The filtrate containing the excreted beta-glucans, but also the mycelium is then freeze-dried.

This (expensive) technique guarantees optimal preservation of the triple helix structure of the ß -glucans, i.e. a biological activity that is not affected. The triple helix structure in most mushroom powders is largely damaged by heating and extraction using solvents.

Triple helix structure

Because we use a sterile substrate that allows the mycelium to develop in a sterile environment, the final product is also not bacterially contaminated. So extremely safe!

Lentinula edodes mycelium LE12 shows a clear genetic similarity to fruiting bodies that grow naturally. Fermedics’ mushroom powders belong to the top of the world due to the advanced & unique production process in which a high concentration of active substances with an enormous stability and high efficiency is achieved.
