There are all kinds of fungus on the market, how do you distinguish and choose fungus?

Step Method.

Take - the fake fungus has something hanging on it in order to gain weight, such as starch, and the real fungus is very light.

Look - some experts use language to describe the color, take the fungus as an example, such as: "The fungus is jet black, adulterated is black gray", friends, can you tell what is jet black and what is black gray? Single.

Color can be, variegated is equal to nothing, if all the problems can be solved, what do you need your eyes for! This is a bad black fungus, everyone can see it at a glance (of course, there are differences in cameras, just for reference).

Break - the fungus itself is thinner, easy to break, and accompanied by a crisp sound, high-quality autumn fungus and mountain fungus due to its thicker, not easy to break, the sound is slightly heavy, if it is a fake fungus, the means of counterfeiting are mostly hanging glue, and mixed with starch in it, tear that is.

Smell - holding a handful of fungus, close to smell, and did not find some experts said "light fragrance", put your head into the bag containing 10 kilograms of high-quality autumn fungus to smell, the smell is minimal, and did not find "light and clear."

incense", during the tasting process, only mountain fungus was found, with a slight smell of bark. Most of us buy fungus in supermarkets and markets, because the smell is mixed and disturbed, and the smell of the fungus itself is minimal, so we think that it has not.

Chemically treated real fungus does not smell any smell, and everyone who has a smell should be cautious to buy, and the statement of "light fragrance" is very irresponsible, which provides a method basis for unscrupulous traders to counterfeit.

Precautions. I suggest that everyone buy less for the first time, and it's never too late to buy more when you're done, and don't buy a lot because of **.
