Yamabushitake mushroom (Hericium erinaceus) is a popular edible mushroom in East Asia.  It is utilized as a traditional Chinese medicinal mushroom.  Kawagishi et al. reported that hericenons and erinacines, components of the fruiting body of Yamabushitake mushroom, can promote nerve growth factor synthesis in cultured astrocytes.  Grape King Bio can manufacture fermented mycelium to produce the erinacine A.

Grape King Bio is a manufacture of functional ingredients for the food, beverage, medical food and pharmaceutical industries.  We can use the fermentation technology to produce many kind of mushroom mycelium such as Antrodia camphorata, Ganoderma lucidum, Cordyceps, Coriolus versicolor, Phellinus linteus, Grifola frondosa, Hericium erinaceum, Lignosus rhinocerus and Armillaria mellea.  These kinds of extracts are mycelium products; they can be food additives and functional ingredients.  For the Hericium erinaceus mycelia, it is brown powder containing at less 8% active polysaccharide.
