How to distinguish the quality of Cordyceps sinensis?
1, specification: Cordyceps sinensis is 3 ~ 5m long and 0.3 ~ 0.8m in diameter, which looks like a three-sleeping old silkworm. Of course, in this range, the longer and thicker the Cordyceps sinensis, the better the quality.
2. Look at the color: the genuine insect body is dark yellow to light yellow brown, the "grass" part is dead branch color, and the color is dark, and the "eyes" of Cordyceps are brown or reddish brown.
3, the number of feet: the authentic Cordyceps sinensis has 8 pairs of feet on the ventral surface, and 4 pairs in the middle of the worm are very obvious. The stroma emerges from the worm's head, and the upper part is slightly enlarged. The length can reach 4-7 cm and the diameter can reach 0.3 cm.
4, look at the shape: 8 pairs of authentic gastropods, 4 pairs of worms in the middle are very obvious.
5. Look at the section: the genuine Cordyceps sinensis has obvious lines after opening, and there is a black core similar to a "V" shape in the middle of the Cordyceps sinensis, and some may also be black spots. This black core is actually the digestive line of insects. Smelling the smell, there is little fishy smell and the aroma of straw mushroom, which is genuine and unique.
Method for identify true and false Cordyceps sinensis
1. Soak Cordyceps sinensis in boiling water. After the Cordyceps sinensis was soaked in boiling water, the worm became swollen and soft, and the color of the worm remained basically unchanged. The color of the fungus seat turns dark brown, and the insect body and fungus seat do not fall off. The water quality is clear and turbid, and the color of the water is pale yellow. Usually, there is no sediment in the water, and even if there is, only a small amount of soil and sawdust will fall off from Cordyceps sinensis. After soaking in boiling water for 10 minutes, the false Cordyceps sinensis will begin to show its original shape. It turns out that the yellow outside the worm will start to fall off. If it is fake, the bacteria will also start to fall off and separate from the worm. Insects may turn into plant roots, ground silkworms and dead silkworms, the dark brown of the bacteria will gradually fade, the color of the water will be abnormal, the water quality may become turbid, and there may be more sediments in the water.
2. Break the worm part of Cordyceps sinensis (preferably from the middle) to see if the cross section is white, if there is a V-shaped black core (black or deep or shallow), and the black core is linear (thick or thin lines). The cross section of Cordyceps sinensis is white, and there is nothing except a V-shaped black core, otherwise it is fake Cordyceps sinensis.
Four steps to distinguish true and false Cordyceps sinensis
1, look at the shape
The head and grass head system of Cordyceps sinensis grow naturally, and the joints are well matched without obvious adhesion marks, which can often be seen by false careful observation; The worm body of Cordyceps sinensis has ring patterns, which are arranged in groups of three rings. The ring pattern near the head is thin, but the fake Cordyceps sinensis is a symmetrical bulge on one side and a stripe with equal parallel gaps on the other side, which is usually cast by mold. According to the number of insect feet, all the true cordyceps are 8 pairs of feet, of which 4 pairs are obvious, and the number of false cordyceps is not fixed, some are 8 pairs, and some are more or less than 8 pairs; Looking at the cross section, we can see that true Cordyceps sinensis is white with obvious lines and a small V-shaped black core in the middle, while false Cordyceps sinensis is likely to have abnormal cross section color or no lines and black core.
Step 2 smell it
The packaged Cordyceps sinensis has a strong smell at the meeting or smells like straw mushrooms and mushrooms. A few cordyceps sinensis can smell this smell when put close, but it is weak. False Cordyceps generally has no smell, and even if it does, it is not this fragrant smell, but it will have fishy smell, inferior perfume smell or chemical raw material smell.
3, try to feel gently grab a handful of real Cordyceps, sprinkle it on your hands, feel the weight, there is a crisp hay feeling, and fake Cordyceps has a heavy feeling in your hands. Rub the insect body and the base of Cordyceps sinensis back and forth on your hands respectively, so that your hands will not be stained or stick to other powdery substances except sand and grass clippings, and vice versa.
Step 4 taste
Cordyceps sinensis is put into the mouth, and the mouth is broken like green beans. The more fragrant it is, the sweeter it is like mushrooms. False cordyceps sinensis is put in the mouth, and the teeth on it are hard to break. After the mouth is soaked, it is full of mud powder, which is not resistant to the mouth and has no meat smell, and the mud smell is strong.
