How can you tell if cordyceps sinensis is fresh? Is fresh cordyceps high in nutritional and medicina

1. Look at the "cordyceps shape": it is to see whether the appearance and shape of each cordyceps are complete. The "insect body" has 8 pairs of small feet, the middle of these 4 pairs of small feet, more obvious and prominent, the surface of the insect body is rough, there are 8-10 groups of circular patterns, each group has three patterns;

2. Look at the "Cordyceps color": the color of the real Cordyceps sinensis ranges from earthy yellow to brownish yellow, and some unscrupulous merchants use some other cheap Cordyceps to imitate, they will use sulfur smoked method, the smoked Cordyceps is golden in color, you can smell the smell of sulfur, this kind of Cordyceps can not be bought;

3. Smell the "cordyceps smell": The real cordyceps sinensis is opened after sealing, and it smells like a straw mushroom with a slightly fishy smell.

Professor Shen Nanying, an authoritative expert on Cordyceps sinensis in China, said: "Fresh Cordyceps sinensis maintains the original ecology and retains 100% nutrition, and its nutritional value and medicinal value are much higher than that of dried Cordyceps, 1 root is worth 3 dried Cordyceps." Therefore, "fairy grass" is coming, creating a "fresh" living era of Cordyceps sinensis chewing at room temperature, and the fresh Cordyceps sinensis will be cleaned within 24 hours through advanced technologies such as cleaning, sterilization, low-temperature cryopreservation, and full distribution of cold chain to ensure that the Cordyceps sinensis you taste is 100% preserved with active nutrients; No additives, no broken grass, no fake grass, no deep processing, 100% retain more than 1,000 kinds of fresh ingredients in the original ecology; At present, it has 7 national patents and PICC product quality assurance, rest assured choice, and take care of the health of you and your family throughout the process!

Cordyceps should appear moist and plump, and the color should be bright. Pure hand fighting, please, dear.

Fresh Cordyceps sinensis is just dug up, not affected by drying, air drying, and natural oxidation, retaining all the nutrients, large, full, good taste, with sweetness, but fresh ingredients can generally only survive for 2 3 days.

The dried cordyceps that you usually see is dry, hard, and has lost a lot of moisture, so it can only be stewed and soaked. Fresh Cordyceps should be moist and full than dried Cordyceps, and the color should be very bright.

1. First of all, look at the color, the surface of the "insect" body of the real Cordyceps silver and summer grass is dark yellow to light yellowish brown, and the color of most insects will change to a certain extent at the combination of insects and grasses. The "grass" part is the color of dead branches and has a darker color.

2. Second, looking at the appearance, there are 8 pairs on the ventral surface of the real Cordyceps, and the 4 pairs located in the middle of the insect body are very obvious.

3. Third, look at the section, there are obvious lines after the real Cordyceps sinensis is broken, and there is a black core similar to "V" in the middle of the Cordyceps, and some may also be a black spot, which is actually the digestive line of the insect.

4. Finally, smell the smell, the real cordyceps sinensis is slightly with the fishy smell of dry Fenghe Na's rotten insect body and the aroma of straw mushrooms.

5 whether it is fresh Cordyceps sinensis or dried Cordyceps sinensis should not be taken too much, generally fresh with about 2-3 roots, dry Cordyceps sinensis if it is health care, then use less than 2 grams, if used as medicine, it is recommended to use 3-9 grams, because Cordyceps sinensis contains arsenic, long-term overdose may lead to chronic poisoning, damage to the human immune system, cardiovascular system, respiratory system, etc.

Cordyceps sinensis has the effect of tonifying lung qi, while radish has the effect of diarrhoea, and eating Cordyceps sinensis with radish may affect the medicinal effect of Cordyceps.

Cordyceps sinensis has a strong tonic effect, and eating cordyceps sinensis will aggravate the symptoms of yin deficiency such as dry mouth and throat, five heart irritations, and less red tongue.

Cordyceps sinensis has a strong tonic effect, mania, high fever, obstruction of stool, abdominal pain and refusal to press, high voice and thick breath, strong pulse and other people with various empirical evidence eating Cordyceps sinensis not only can not achieve the purpose of health care, but also will lead to nausea, upset, bleeding at the corners of the mouth and other adverse reactions.

Cordyceps sinensis has a tonic effect, and it is not advisable to take tonic when the external fever is felt, otherwise it will cause the evil qi in the body to not go out, resulting in the aggravation of external fever symptoms, and even other uncomfortable reactions such as nausea and vomiting.

Cordyceps sinensis has a certain effect of tonifying the kidney and aphrodisiac, similar to the effect of male hormones, the development of various organs in the body of minors is not yet perfect, and long-term consumption of Cordyceps sinensis may lead to precocious puberty.

Cordyceps sinensis is a precious Chinese medicinal material in China, which has been regarded as a nourishing treasure since ancient times. It has a variety of effects such as regulating immune system function, anti-tumor, and anti-fatigue. Together with ginseng and deer antler velvet, it is listed as one of the top three tonic medicines in China.

As early as the Qing Dynasty, it was recorded in the "Materia Medica". Because of its preciousness, it is known as "**grass", and is also called "soft**" in the folk, and because of its unique nourishing effect, it is called "fairy grass" in Qinghai-Tibet. The following is the nutritional value and preservation method of fresh cordyceps sinensis that I bring to you, welcome to read.

According to the "Dictionary of Traditional Chinese Medicine", Cordyceps supplements deficiency, benefits essence and qi, treats yang spasms, waist and knee pain, and weakness after illness. Cordyceps contains a large amount of protein and amino acids, as well as the key ingredients to ensure the efficacy of Cordyceps, Cordycepin and adenosine, etc., which are easy to volatilize and oxidize during the drying process, and these active ingredients will lose more than 50% during the drying process. Generally, people with weak constitution need to eat 5 or 6 sticks of dried cordyceps a day, while fresh cordyceps only need 2 or 3 sticks.

Our common cordyceps sinensis is made by fresh cordyceps sinensis harvested and then brushed (to remove surface dirt) and dried in the shade. In the process of drying, the water evaporates by 30%-50%, and at the same time as the water evaporates, the nutrients in the Cordyceps body are also lost rapidly with the evaporation of water, which greatly reduces the efficacy of dried Cordyceps.

The fresh Cordyceps harvested in the peak season not only has a full insect body, but also a lush and fat seedling, high quality and efficacy, and is relatively cheap. However, it is necessary to master the correct method of preserving fresh Cordyceps, otherwise fresh Cordyceps is very easy to become moldy, moth-eaten and deteriorate.

1. The freshly purchased cordyceps is mostly black with soil, and will be brushed clean with a medicated toothbrush before being sealed and dried.

2. The preservation principle of fresh Cordyceps sinensis is freezing, vacuum, and drying. If you don't buy a lot of money, it's best to eat it as soon as possible.

3. Fresh Cordyceps can be stored in the freezer compartment of the refrigerator from minus 5 to minus 10 for preservation, and can be taken at any time.

4. Once the frozen cordyceps is thawed, it should be eaten immediately. Because fresh Cordyceps will continue to breathe and grow after thawing, consuming nutrients.

5. Freeze it in the refrigerator for up to 6 months, otherwise the nutritional value will be reduced.

Cordyceps, also known as Cordyceps, is usually identified as follows:

Genuine: It is strip-shaped, composed of two parts connected by the insect body and the bacterium, the total length is about 9-12 cm, the insect body is like a silkworm trunk, about 3-6 cm, about centimeters thick, dark yellow, medium yellowish brown, rough appearance, obvious annular lines, there are 20-30 links, there are 8 pairs of abdomen, 4 pairs are located in the middle of the insect body, the quality is brittle and easy to break, the section is full of heart, and the white is slightly yellow. The bacterial base grows from the head of the worm, curved rod-shaped, the upper part is slightly larger, grayish-brown or black-brown, the section is empty, pinkish-white.

The taste is sweet and slightly bitter, with a slightly fishy smell.

Fake: mostly the dried rhizomes of the Lamiaceae plant grass stone silkworm (also known as the ground silkworm), the shape is like a spindle, the surface is pale yellow to gray-yellow, the links are obviously less than the real product, only 2-11, the abdomen has no feet, the shape is like a larva, there is no child seat, the texture is brittle, easy to break, the section is white, powdery, the taste is sticky without the fragrance of straw mushrooms, and the taste is slightly sweet. In addition, there are fake Cordyceps made of starch, flour, corn flour, a little gum, pigment, and pressing, and some inferior Cordyceps with metal wires inserted into the insect body, etc., which are not suitable for purchase.

Cordyceps flowers are also called Cordyceps militaris, Cordyceps militaris, etc., the market is mixed, because ** is not high, so there are not many fakes, just the difference in quality. So how to choose high-quality Cordyceps?

1. Look at the color: high-quality new Cordyceps flowers are natural golden yellow, and the color is black and dark, which is defective, and it is cheap; The whitish color is either improperly stored, and it turns white when stored in the sun for a day or two (carotenoid characteristics), which has little effect on the quality; Either it's too old and not very fresh.

2. Smell the smell: high-quality cordyceps flowers have a grass fragrance, and the bad ones have a strong musty smell and are easier to distinguish.

3. Thickness: The quality of Cordyceps flowers is not proportional to the thickness, and the branches in Cordyceps flowers are complete and have good toughness.

Look at the feet: There are eight pairs of real cordyceps, which are very clearly arranged under the abdomen; And the fake ones are either not in the right quantity, or they are not clear and have a blurry shape.

Look at the back pattern: The pattern of Cordyceps is three narrow and one wide, and it is very regularly distributed, and it is clear. The fake grass is not so regular or unnoticeable.

Look at the eyes: The eyes of the real grass are small and distributed on both sides of the insect body; And the eyes of the false grass are bright and large, which is very obvious.

1. Shape: 3-5cm long, 20-30 rings, 8 pairs of feet, 4 pairs in the middle are clear and obvious.

2. Color: yellow or yellow-brown appearance, pale yellowish-white gastropod, reddish-brown head.

3. Section: white, with a black tube running through the full length of the insect-shaped sclerotia in the middle, which is the digestive tube of the larvae of Cordyceps bat moth. The section does not have a black pipe as a fake. (The section is yellow, it may be soaked in heavy metals, or Cordyceps sinensis has been decocted).

4. The head of the grass (sub-seat) grows out, and the insect part and the sub-seat are tightly pulled continuously. It is not cordyceps sinensis that can be easily pulled off.

5. Smell: slightly fishy.

How to eat: 3-9 grams of cordyceps, broken and stewed duck (chicken, pig, fish, sheep, beef). Take it twice in the morning and evening, and it is best to eat it together with Cordyceps. It can be taken continuously for 30-180 days to have an effective conditioning effect.

Cordyceps is not a miracle medicine, Cordyceps sinensis is mainly used to nourish the lungs and kidneys and improve immunity. Traditional Chinese medicine has long determined that Cordyceps sinensis is warm, so it is not suitable for people with all physiques, especially for hot constitutions, please use it under the guidance of a doctor. Ordinary people can use cold water to wash and then soak in water instead of tea, or add a little ginseng or chrysanthemum, peaceful and hot, repeatedly soaked and drunk and finally chewed, in fact, no matter which way of taking:

Stewed soup, soaking water, powdering in fact, it doesn't matter, being able to eat the effect is the key, since it is a traditional medicine to follow the tradition, now there are too many online sales products, it is good to have a discernment, and take it purposefully under the guidance of a doctor, otherwise it will be a waste of money not to say, but to harm the body.

Cordyceps sinensis must have both "grass and insects" when it is used in medicine, and the medicinal properties are good, if one is missing, the efficacy is incomplete. In the case of incomplete Cordyceps, there is only a worm body without a sub-seat, or only a sub-seat without a sub-body; They are all defective, and this is the most important point, so don't forget it. When buying medicinal Cordyceps, you should choose one with normal color, good development, no diseases and pests, no defects, no deformities, good texture and dryness.

These well-known domestic brands of Cordyceps brands, such as Fulinmen and Tongrentang's Cordyceps, all have the above characteristics. FLM is more affordable for household customers, while Tong Ren Tang is for business gifts, and the price is higher than the former.

Identification methods are, traits.

Complex, microscopic system, physical and chemical identification.

Let me talk about the traits, because microscopic and physicochemical methods are identified by instruments.

Cordyceps sinensis is made by connecting the body of the insect to the seed seat of the fungus growing from the head of the insect body. The body of the insect is like a silkworm, 3 5 cm long, diameter; The appearance is earthy yellow to yellowish brown, occasionally brown, rough, with obvious rings, a total of 20 30 rings, and the rings near the head are finer; There are 8 pairs of feet on the whole body, 3 pairs near the head, 4 pairs near the middle, 1 pair near the tail, with the 4 pairs in the middle being the most obvious; The head is reddish-brown and the tail is like a silkworm's tail. Brittle, easy to break, slightly flat section, light yellowish white.

The subtraction is dark brown to tan, elongated, cylindrical, generally longer than the body, 4 7 cm long, about 3 mm in diameter; There are fine longitudinal wrinkles on the surface, and the upper part is slightly enlarged. Flexible, fibrous on the fracture surface, off-white. The smell is slightly fishy and the taste is slightly bitter.

It is better to be complete, the body of the insect is plump and fat, the outer color is yellow and bright, the internal color is white, and the sub-seat is short.

Counterfeits are, 1Cordyceps sub-fragrant. It is a cordyceps hawkes.

2.Pupa. Yunnan, the main production of Guangxi. Cordyceps sinensis fungus isolated for artificial culture is synthesized artificially. Make substitutes.

In winter, the larvae of the bat moth sting in the soil, and after being infected with the Cordyceps fungus, the body is gradually filled with hyphae and dies back, and in the summer the hyphae develop from the host.

The head of the answer is protruding from the ground, like a baseball bat, and is composed of many hyphae; The head is slightly enlarged, except for the tip small, densely packed with many ascomycetes, and the tip of the oval ascomycete shell is convex on the surface of the subbase. The insect body of dried medicinal herbs resembles an old silkworm, earthy yellow to yellowish brown, a few brown, with 20 30 obvious annular lines, 8 pairs of feet, and 4 pairs in the middle are more obvious; A small yellowish-red head visible at the base of the subbase; Brittle, easy to break, slightly flat section, white and slightly yellow, dark brown "V" pattern can be seen in the middle. The subtraction is solitary, dark brown to tan, slender and rod-like and curved, with longitudinal fine wrinkles on the surface; The tip of the ascomycete shell of the head is collapsed and the surface is uneven; infertility is pronounced at the apex; It is flexible and not easy to break, and the longitudinal tear surface is white fibrous.

The smell is slightly fishy and the taste is light. Cordyceps sinensis has a complete insect body, plump and hypertrophied, yellow and bright on the outside, and pink and white on the inside; The sub-seat is stout and flexible, and the color is bright brown. A small color is dark, followed by a dense body; Cordyceps fragmentation should be seen poorly.

If it is stored for too long, the insect body is dry and hard, the internal and external colors are dark, and the quality is inferior. Generally, the Tibetan Cordyceps is strong, the color is yellow and bright, and the Cordyceps vulgaris is weak, and the color is darker. This is related to the regional climate, soil and other growth environments, but it is also affected by the microecological environment.
