Shiitake are local to Japan, China and Korea and
have been developed in every one of the three nations since ancient
times. In Japan, the most established record in regards to the
shiitake mushroom dates to AD 199 at the time of Emperor Chūai. The
principal composed record of shiitake development could be followed
to Wu Sang Kwuang in China, conceived amid the Song Dynasty. Amid the
Ming Dynasty, doctor Wu Juei composed that the mushroom could be
utilized as a sustenance and as a therapeutic mushroom: taken as a
solution for upper respiratory illnesses, poor blood course, liver
inconvenience, fatigue and shortcoming, and to help qi or life
vitality. It was additionally accepted to counteract untimely
maturing.
The Japanese developed the mushroom by cutting shii
trees with tomahawks and putting the logs by trees that were at that
point developing shiitake or contained shiitake spores. Before 1982,
the Japanese mixture of these mushrooms could just be developed in
conventional areas utilizing old techniques. In 1982, Gary F. Leatham
distributed a scholarly paper focused around his examination on the
maturing and development of the Japan Islands mixed bag; the work
helped make business development conceivable in the United States. In
1974, aggregate creation was assessed at around 143 000 tons, with
Japan speaking to 94.5% of the aggregate, China 4.2%, Taiwan 1.1%,
and South Korea 0.2%. In 1997 China's shiitake generation had climbed
from 4.2% to 85.1%.
