As a rare and precious medicinal material, wild Ganoderma lucidum has limited resources and generally higher price, while cultivated Ganoderma lucidum is much cheaper. At present, there are only two kinds of Ganoderma lucidum that can be cultivated on a large scale in China, and other varieties can not be cultivated yet. So, how to judge whether the bought Ganoderma lucidum is wild or cultivated?
The following introduces the identification of wild ganoderma lucidum and cultivated ganoderma lucidum. The simple identification method is to use hands and eyes:
Use your hands. Directly pressing the surface of Ganoderma lucidum, if it can be easily pressed in, is artificial cultivation of Ganoderma lucidum. Due to the short growth period of cultivated Ganoderma lucidum, the texture of fruiting body is relatively loose; Wild ganoderma lucidum grows in the wild for a long time, and its texture is very hard, so it can't be pressed in by hand. The stems of wild Ganoderma lucidum are smooth and feel as smooth as glossy oil. False ganoderma lucidum, that is, cultivated ganoderma lucidum, has thick stems and eyes. Wild ganoderma lucidum grows in different environments in the wild, so each ganoderma lucidum is very different, its surface is not smooth and it looks black and old. The cultivated Ganoderma lucidum grows in the same environment, and each Ganoderma lucidum looks similar and has a bright surface, so it is called the "flower" cultivated in greenhouse. The stems of wild Ganoderma lucidum with a diameter of 8 cm are generally about 4 inches long, and the stems of cultivated Ganoderma lucidum are relatively short (these need to be known by experienced people). The roots of wild Ganoderma lucidum are often stained with soil or black rot wood roots. Wild Ganoderma lucidum (floret) below 8 cm, the edge of the fungus surface is generally yellow circle (that is because it was picked before the growth period), and the middle is black and shiny; Wild Ganoderma lucidum over 8 cm, the whole mushroom surface is black (because it is old enough). The roots of planted Ganoderma lucidum are not stained with mud or rotten wood, and vendors often cut off the roots. Because the planted Ganoderma lucidum is to cut a hole in the fallen wild wood and then plant the seeds of Ganoderma lucidum in it, the grown Ganoderma lucidum is not stained with mud or rotten wood (of course, some people often cut off the roots of wild Ganoderma lucidum for neatness and beauty). In addition, cultivated Ganoderma lucidum, more than 8 cm, often has a yellow edge (black in the middle), while wild Ganoderma lucidum does not have this phenomenon.
In addition, the wild ganoderma lucidum stew is delicious, sweet and delicious. Other places say that Ganoderma lucidum can't stew chicken, which will be very bitter, but there is no such phenomenon in Jinxiu Dayaoshan Ganoderma lucidum, which shows that Ganoderma lucidum is fake and poor. Some unscrupulous traders often steam wild ganoderma lucidum once or twice before selling it. Such ganoderma lucidum is greatly reduced in nutrition and even has no nutrition. The difference between steamed ganoderma lucidum and non-steamed ganoderma lucidum: the surface of steamed wild ganoderma lucidum looks the same as that of ordinary wild ganoderma lucidum, but careful observation will reveal that its stem or mushroom surface is greasy, with a feeling of "touching" with fingers, a little oily. Furthermore, the surface of steamed ganoderma lucidum is relatively clean, old and dull, while the surface of wild ganoderma lucidum without steaming is usually stained with dirt and dust, shiny, smooth to the touch and not sticky.
Due to continuous picking, the number of wild ganoderma lucidum is decreasing year by year, but the number of wild ganoderma lucidum is very small, and most of them are planted in the market. Wild ganoderma lucidum is actually very different from growing ganoderma lucidum. According to the current level of agricultural science and technology, the cultivation of Ganoderma lucidum is scientific and safe in terms of strain selection, control of growth environment conditions, and optimal harvest time. Don't deify ganoderma lucidum.
(2) Generally, the fruiting bodies of Ganoderma lucidum can be judged from the shape, color, thickness and specific gravity. Good log Ganoderma lucidum has round or kidney-shaped fruiting body, short stalk and thick meat. The back or bottom of its hat, that is, the part where the pores can be seen with a magnifying glass, is generally light yellow or golden yellow, followed by white and grayish white, and the one with larger pores is the worst. This ganoderma lucidum sporophore sprayed with spore powder, that is, the nutrition is transformed into spore powder and sprayed out, and the effect is also poor.
(3) There are three main ways to distinguish bag-planted Ganoderma lucidum from log Ganoderma lucidum. First, the specific gravity of bagged Ganoderma lucidum is light; second, the stalk of bagged Ganoderma lucidum is long; third, the back of the mushroom cap of bagged Ganoderma lucidum is light in color, generally white, and rarely golden in color.
(4) Wild Ganoderma lucidum was eaten by insects when it was young, and many other polypores were mixed in it. It is not only nutritious, but also harmful, so we should pay attention to eliminating it.
