Coming from Asia (mainly Japan and China), the shiitake is currently the most cultivated mushroom in the world and is recognized as a species of pleasant taste and attractive aroma, qualities that have favored its wide commercial distribution. The sensory qualities of shiitake have allowed it to quickly become incorporated from Asian cuisine into world gastronomy. Nowadays it is frequent to find different dishes based on shiitake and it has more and more presence in the markets of America and Europe in very different forms.

The popularity of the shiitake has increased in good part by its exotic flavor, but also by its well-known nutritional and medicinal properties. Shiitake is a good source of vitamins among which the B complex stands out, mainly vitamins B1 (thiamine), B2 (riboflavin), B3 (niacin), and B12 (cobalamin), folic acid, as well as vitamins C and D. It also provides significant amounts of minerals such as calcium, phosphorus, iron, sodium, magnesium, zinc, and potassium. Shiitake contains almost all the essential amino acids for good nutrition of the human body with especially abundant amounts of alanine, arginine lysine, and leucine, while methionine, histidine, and phenylalanine are less abundant.

These mushrooms are also a good source of dietary fiber (6.7% in dry weight), which gives them important properties in the prevention of constipation, diabetes, obesity, hypertension, colon cancer, and arteriosclerosis, as well as lowering cholesterol levels. Shiitake is accepted worldwide, not only because of its excellent aroma, taste, and nutritional characteristics, but also because of its medicinal properties. These are mainly attributed to the presence of structural polysaccharides and heteropolysaccharides, as well as terpenoids, among others.

The mushroom contains vitamin C and high amounts of ergosterol, a provitamin which in the presence of sunlight is converted to vitamin D, as well as niacin, thiamine, and riboflavin. Vitamin D is necessary for the absorption of calcium and phosphorus and has positive effects on the treatment of colon cancer. Shiitake also contains protein, carbohydrates, fiber, vitamins, minerals, and lipids. The amount of protein fluctuates from 13 to 35% of the dry weight. It has between 67 and 79% carbohydrates. The fat content in the mushroom is low, 0.5-5%, which represents an advantage from the health point of view. The lipids present are oleic and linoleic acid, which make up 73-77% of the total fat.

The daily consumption of only 90 g of fresh shiitake during seven days induces the reduction of up to 12% of the cholesterol in the blood.

Currently, there is solid scientific evidence based on chemical analysis and the use of in vitro, animal, and human models. This fungus has a beneficial effect against high blood pressure, liver diseases, among others; this makes it a product of great interest in public health. Shiitake not only represents a source of nutrients for consumers, but has also been used as a medicinal tonic for over two millennia. In the last decades, many of its properties attributed by the Asian traditional medicine have been scientifically demonstrated. The bioactivities of shiitake such as antiviral, antimutagenic, antinociceptive, anti-inflammatory, cytostatic, anticancer, and immunomodulating, have been widely studied.

Shiitake mushrooms have the peculiarity of presenting a very exquisite flavor, although somewhat strong for the palates that are not used to its consumption. Especially in the dehydrated product, its sensory characteristics are increased, so it is recommended to consume them in small portions and to increase its tasting gradually, until its flavor is enjoyed to the maximum. If the mushrooms are fresh, they should be cleaned with a dry cloth to remove any foreign particles, such as residues from the growing substrate. If it is necessary to wash them, place them preferably at the tap, avoiding leaving them submerged so that they do not absorb excess water. If the mushrooms are dehydrated, they should be left to soak for 30 minutes in warm water so that they recover their natural appearance.
