Lentinula edodes Fruiting Body Identity & Part
The botanical entity is Lentinula edodes (Berk.) Pegler, a wood-decay fungus of the family Omphalotaceae that is cultivated on hardwood logs or sawdust blocks. The part used is the fruiting body, the mushroom itself. Mycelium and the growing substrate are not added to this shiitake mushroom extract.
The fruiting body can be dried whole, as caps or as stems, and each carries a different texture and fiber content, so a specification should name the fraction. Shiitake contains beta-glucan polysaccharides including lentinan, together with proteins, ergosterol and the nucleotide guanylate, which contributes to its savory, umami taste. Water extraction concentrates the soluble polysaccharide and flavor fraction.
